Development of CNC processing industry in 2021

2021 is destined to be an extraordinary year. At present, the domestic epidemic situation has been stable, while the foreign epidemic situation is still rising. For the machinery manufacturing CNC processing industry, the business impact on the foreign trade market is very large. Where is the development direction in the second half of 2021? Let’s take a look at the following points:

  1. The foreign market has a huge impact: many of them have not returned to work, and the demand for CNC processing is almost zero. But we can not give up the market, take the initiative to contact customers, and at the same time open up new markets.
  2. Large domestic demand, seize the opportunity: it can be said that the domestic epidemic has been completely controlled, the demand of all walks of life is rising, especially the precision CNC processing customers, such as electronic optics, mobile communication, medical equipment and other industries, need CNC processing outsourcing cooperation. As long as we do a good job in quality and service to customers, orders will grow slowly.
  3. Independent innovation, R & D of products: for the mechanical processing industry, R & D of products is a very difficult thing. We need technology without technology, market without market, and talents without talents, unless we have abundant funds, talents or market demand.

Introduction of computer gong machine tool

1) Casting, which is the most important part of the computer gong, directly affects the accuracy, stability, wear resistance of the computer gong and the service life of the machine tool. After the casting is finished, it is not immediately used in the production. The good casting is that it is after wind and rain, sun exposure, natural weathering, and some of them are soaked in sea water. After the casting does not change, it is taken to the processing. The machine tool made in this way is not easy to change, and can maintain the stability and accuracy of the machine tool for a long time.

2) Spindle, the spindle is used to directly face the workpiece, it is driven by the motor to work, high-speed rotation, the spindle is equipped with a tool handle, it can chip the workpiece, meet various production needs, the quality of the spindle will directly affect the processing accuracy, if the internal bearing is worn, it is easy to cause the swing of the spindle, the accuracy of the processed things naturally has a few deviations . At present, the rotation speed of the main shaft is generally about 8000 rpm, and the high-speed machine can achieve more than 20000 rpm, and each machine has only one main shaft.

3) The screw rod is also a part of the fuselage. It is driven by a servo motor and drives the displacement of the worktable through the copper sleeve of the screw rod to meet the processing needs. If there is a gap in the screw rod, it is also directly reflected in the processing accuracy and finish.

4) There are two kinds of motors: servo motor and frequency conversion motor. The servo motor has good stability, high power of spindle drive motor and low coordination rate of three-axis drive motor.

5) The coupling is installed between the screw rod and the motor, which is just a linkage function.

6) The lubrication cooling system consists of an automatic oil pump, a spindle oil cooler and a chip liquid circulation system. When the machine tool is working, the oil can be pumped once every few minutes, and the oil pipe is connected to every corner, such as screw rod, guide rail, etc. if the oil circuit is blocked, the guide rail will be easily worn and the accuracy will be affected. Spindle oil cooling is a circulating cooling system added to cool the spindle. It is necessary or not for the spindle with 8000 revolutions, and it must be equipped for the spindle with more than 8000 revolutions. In the chip liquid circulation system, the oil in the oil tank is pumped up by the oil pumping motor and flushed to the workpiece being processed.

7) Sheet metal, sheet metal requirements are not too high, as long as there is no oil leakage on the line, but also involves the appearance of beautiful, image problems.

In order to improve the service life of stamping die or plastic die (including injection die, extrusion die, blow mold, etc.), the relevant parts of die cavity are generally made of high-strength wear-resistant materials (such as various grades of alloy structural steel, alloy tool steel and stainless steel, etc.), which have high hardness after heat treatment and are difficult to be machined by conventional machining Methods to process. For decades, the best way to deal with this kind of difficult to machine materials is to use special machining.

Discussion on precision mold processing technology

Since its invention in Europe in 1920s, fine blanking technology has experienced more than 80 years. It is one of the most important precision plastic forming methods in the field of thick plate manufacturing. It is a method with high technical content and good economic benefits for the economic production of large quantities, high quality, multi-functional ferrous and non-ferrous metal parts. Fine blanking press completes a stamping process, through the processing of special fine blanking die, one or more high precision forming parts can be produced, which can be directly used for assembly. It has been widely used in the fields of electronics, computer, electric power, home appliances, automobile and aviation. According to incomplete statistics, there are about 4500 fine blanking machines and 10000 parts produced in 40 countries in the world. For example, there are nearly 100 kinds of fine blanking parts in a car (car), including gearbox fork, seat and seat belt angle adjuster, planetary gear, brake shoe and steel back.

China’s fine blanking die technology has made great progress in the Eleventh Five Year Plan period, and has made a series of scientific research achievements in fine blanking process, materials, fine blanking press, die base, die and lubrication. As of the end of 2008, nearly 20 provinces and cities in China have professional fine blanking production equipment, with more than 80 fine blanking presses (excluding hydraulic mold base), more than 5000 fine blanking employees, producing about 2000 kinds of fine blanking parts, and a number of independent fine blanking mold development demonstration bases have been formed. Metal materials are expanded from non-ferrous metal blanking to ferrous metal blanking. The blanking thickness of low carbon steel, low alloy steel and stainless steel can reach 12mm; the blanking thickness of non-ferrous metals such as aluminum alloy and copper alloy can reach 18mm; with the progress of die materials and treatment methods, as well as the spheroidization process of the punched plate Some hard high carbon steel, high alloy steel and other low toughness materials such as nickel base or cobalt base alloy materials are also used in the production of fine blanking parts. In addition, the proportion of self-developed progressive compound fine blanking die, transfer die and modular die in domestic fine blanking die has increased significantly, especially the progressive compound fine blanking die for complex parts of automobile transmission system has basically realized localization.

The research, development and application of finite element numerical simulation technology, structure optimization technology of fine blanking die, intelligent design and knowledge base technology of fine blanking die improve and enrich the technical connotation of fine blanking die in China. However, at present, the fine blanking enterprises are generally small in scale, scattered in resources, low in production efficiency, shortage of talents and incomplete in supporting. Although in the fine blanking die development has a certain development ability.

CNC computer gong programming matters needing attention

  1. The speed of white steel knife should not be too fast.
  2. Copper workers use less white steel knives and more flying knives or alloy knives.
  3. When the workpiece is too high, it should be roughened by layers with knives of different lengths.
  4. After roughening with a big knife, use a small knife to remove the remaining material to ensure that the remaining material is consistent.
  5. The plane should be processed with flat bottomed cutter and less ball cutter to reduce the processing time.
  6. When cleaning the corner, check the size of R on the corner first, and then determine the size of the ball knife.
  7. The four corners of the calibration plane should be level.
  8. Where the slope is an integer, the slope cutter shall be used for processing, such as pipe position.
  9. Before each process, think about the remaining allowance after the previous process,

In order to avoid the blank tool or too much processing and knife.

  1. Try to use simple cutting path, such as shape, trenching, single side, less walking around and so on.
  2. When walking wcut, those who can walk finish should not walk rough.
  3. When the shape of the knife is smooth, rough first and then fine. When the workpiece is too high, smooth the edge first and then the bottom.
  4. Set reasonable tolerance to balance machining accuracy and computer calculation time. The tolerance is set to 1 / 5 of the allowance for roughening and 0.01 for smooth cutting.
  5. Do more process to reduce the time of empty tool.

Do more thinking and reduce the chance of mistakes.

Do more auxiliary lines and auxiliary surfaces to improve the processing condition.

  1. Establish a sense of responsibility and carefully check each parameter to avoid rework.
  2. Be diligent in learning, good at thinking and make continuous progress.

17 milling non planar, more ball cutter, less end cutter, do not be afraid of the knife;

18 small knife clear angle, big knife refined;

Don’t be afraid of patching, proper patching can improve the processing speed and beautify the processing effect

20 high hardness of blank material: reverse milling is better, low hardness of blank material: forward milling is better

Good accuracy, good rigidity and finishing: it is more suitable for forward milling, otherwise it is more suitable for reverse milling

It is strongly recommended to use forward milling for finishing the inner corner of parts.

Rough machining: reverse milling is better, finish machining: forward milling is better

Tool material toughness is good, low hardness: more suitable for rough machining (large cutting amount processing)

Poor toughness and high hardness of tool material: suitable for finish machining (small cutting amount machining)

Is Internet marketing the way out for computer gong processing

In recent years, the machining center is becoming more and more powerful. Among all kinds of imported CNC metal cutting machine tools, the machining center has become the most important import product, and its quantity and amount account for one third of the imported CNC metal cutting machine tools. Its rapid growth rate reflects the great demand for this product in our country.

The situation that most of the domestic demand processing centers depend on foreign imports has not fundamentally changed, and the domestic market share is still low, about 27%. The main reason for the low market share of domestic products is that there are many gaps in product level, delivery time, quality and reliability compared with foreign similar products. So the products we import mainly come from Japan, South Korea and Taiwan. In the face of these foreign countries, we use CNC machine tools, flexible manufacturing cells and flexible manufacturing systems to achieve large-scale production. Relatively speaking, foreign products have shorter delivery time and better quality stability. Due to the small production scale of domestic popular vertical machining center, the annual output of most enterprises is about hundreds, and individual enterprises can reach about 500. There is a gap between domestic and foreign similar products in terms of delivery time and quality, and the price advantage is not big, so they lose the market in the competition.

The Internet is closely related to our life now. We will use the Internet for many things, especially now that many young people are staying at home and almost do not go out. We call this kind of people “otaku men and otaku women”. From the perspective of the general quadrant of society, we know that the Internet has almost completely occupied our life. Now that the Internet has become the mainstream of our life, we can see that the Internet has become the mainstream of our life Network is so popular, so many of our enterprises think of doing business on the Internet, which is what we call network marketing. Many enterprise owners will do network marketing now, so as to eliminate the traditional way of sales. Network marketing can make you worry and labor-saving, and also earn an apology. Why not? So if our machining center wants to develop better, the network must be a breakthrough.

Machining center machine can be said to be the mechanical equipment used in numerical control, and this equipment is really the same as the name of this equipment. It is the application center control system of mechanical equipment, which plays a great role in the application of mechanical equipment, and we also play a great role in the application of this equipment.

Now many enterprises are doing this processing center, the market competitiveness is very strong, and generally are small and medium-sized enterprises to do, their products and this approach are roughly the same, so the competitiveness between peers will be more powerful, so many manufacturers change to price this piece of sales, peers have reduced the price, but for a long time this is not the case What kind of sales method is still not good, we still need to change the sales method. In the current situation, e-commerce is the only way out for enterprises. Compared with the cost of traditional exhibitions, magazines, newspapers and TV promotion, the cost of e-commerce is nothing.

New energy development

In China, the amount of conventional energy resources is only 60% of the world average level. In order to meet the growing energy demand, it is necessary to accelerate the development and utilization of new energy. At present, the 9% share of new energy in the energy structure is relatively low compared with the developed countries in the world, and there is still a lot of room for development.

Although the latest statistics of 2008 have not been released yet, the proportion of China’s new energy production in the overall energy structure will exceed 9% based on the data from various aspects, especially the growth rate of China’s new energy production and consumption in the past 10 years.

2008 is an extraordinary year for China’s energy work. Affected by the changes of the world macro-economic situation and natural disasters, the supply and demand of energy has experienced a roller coaster like operation from “tight supply” at the beginning of the year to “demand slowing down” at the end of the year. Authoritative experts pointed out that the easing of the tense situation of energy supply and demand does not mean that China’s energy demand has dropped significantly, nor does it mean that China’s energy supply can achieve absolute self-sufficiency. Therefore, the task of developing new energy is still urgent. Compared with the level of developed countries, 9% of new energy in China is still at a relatively low level.

In 2007, China produced 2.35 billion tons of standard coal, of which coal accounted for 76.6%, oil accounted for 11.3%, natural gas accounted for 3.9%, and other unconventional energy accounted for 8.2%; while the total energy consumption in this year was 2.66 billion tons of standard coal, including 69.5% of coal, 19.7% of oil, 3.5% of natural gas and 7.3% of unconventional energy. In terms of total amount, there is still a gap in energy consumption in China. From the structural analysis, in China’s energy structure, the dominant position of coal has not changed. Although the development speed of new energy is fast, its proportion is still too small.

China has a long way to go in developing new energy, whether in terms of structure or total demand. First of all, the development of new energy is an effective guarantee to maintain rapid economic growth. From 2003 to 2008, the average annual growth rate of China’s GDP is close to 10%. In order to maintain the stable and sustainable development of economy, we must have strong energy guarantee. Throughout China’s resource reserves, the total amount is large and the per capita share is small, so it is difficult to form a sustainable support only relying on traditional energy.

Secondly, the development of new energy is an effective way to alleviate environmental pressure. Compared with traditional energy, new energy has the characteristics of less pollution and high efficiency. Vigorously developing new energy will help to reduce economic losses caused by environmental damage and achieve the goals set in the eleventh five year plan.

Third, the development of new energy is an effective means to ensure the safe supply of energy. Energy security is an important part of a country’s economic security and an important barrier to ensure the independent and healthy development of a country’s economy. At present, China has to import a part of its oil every year, and its dependence on foreign countries is relatively high. To ensure the safe supply of energy, we must adhere to the diversified strategy, and vigorously developing new energy is the concrete embodiment of this strategy.

Fourth, the development of new energy is a powerful weapon to solve the dilemma of unbalanced regional development in China. There is a big gap among regions in China, which is unfavorable to the sustainable development of economy and society. The development of new energy in the vast western regions and remote rural areas not only improves people’s livelihood, but also promotes economic development.

Fifth, it is feasible to develop new energy. With the improvement of technical level, the cost of new energy development has dropped sharply, and the cost of some new energy has been close to or even lower than that of conventional energy.

The reporter interviewed the national energy administration and relevant people in the industry. The unanimous judgment is that the development trend of China’s new energy will, on the whole, maintain a sustained and rapid development momentum and have a bright future.

From the perspective of policy environment, the recently concluded energy work conference has determined the work direction with the theme of structural transformation, which indicates the arrival of a new era of new energy industry. Both the promulgation of new energy and renewable energy planning and the implementation of the new energy law in the future have brought unprecedented opportunities for the development of new energy.

From the perspective of investment, international capital is optimistic. Even in the context of the international financial crisis, investment in the field of new energy will still become the hot spot of capital pursuit. Under the influence of policy guidance, domestic capital will follow suit one after another. The continuous rise of new energy sector in A-share market is sufficient evidence.

From the perspective of the internal structure of new energy, the priority development direction in the future is still wind energy, solar energy and nuclear energy with high technology maturity and economic feasibility. Economic feasibility is an important bottleneck restricting the development of new energy, which will be solved gradually with the improvement of China’s technical level.

Processing automobile parts with computer gong

With the development of society, gold casting technology has been greatly improved. In the production process, it also reduces the environmental pollution, improves the working environment, improves the production technology and level, which is of great help to the development of the casting industry, so as to promote the development of the automobile industry. The domestic and international markets have more and more stringent requirements on the quality and cost price of automobile forgings, such as draft angle, weight tolerance, size, machining allowance, etc., and the price is not ideal, but the batch is large. In order to meet the needs of the market, this paper analyzes the process and repeated practice, and finds an ideal process, which is of great significance to the production of similar products.

Introduction of products and determination of process plan

The arm body is a part used on the brake pump of a heavy vehicle, and the structure is shown in Fig. 1. There are several difficulties in forging: (1) the draft angle is small, only 3 ° outside and 5 ° inside, while the ejection device only has one place in the ∮ 62 hole; (2) the machining allowance is small, only boring and broaching are used for ∮ 62 and square groove of 23.2mm; (3) 10 – ∮ 6.2 * 5 these 10 nails are difficult to fill, and the location requirements are high, and the root fillet of the nails is r0.2, which makes the die wear faster and easy to bump and cause deformation in the production process.

Determination of process plan

In order to adapt to mass production and improve efficiency, we have determined the following processes: (intermediate frequency furnace) heating / (cross wedge rolling) / (25000kN hot die forging press) bending / pre forging / final forging / (3150kN double point press) punching / trimming / normalizing / shot peening / precision pressing. In the technological process, two pieces at a time are used for heating billet, the handle of the part is long and thin, and the blank making efficiency of single piece by free forging is low. The cross wedge rolling billet (as shown in Fig. 2) is adopted and cut into two pieces on the rolling mill at the same time. Because the cross section of the parts changes greatly, it takes two wedges to complete from ∮ 55 to ∮ 23, so it is difficult to process and repair the rolling die.

In addition to ensuring the size of the head and shank, it is more important to correct the position of the 10 nails, the fillet of the root and the bending of the handle. Therefore, two standard platens with 5 holes are used to ensure the position of nails and the root fillet, and improve the service life of forging die.

Key points of mould design and manufacture

Generally, the bending die design only considers that the shape of the extruded blank is consistent with that of the forging. Due to the large difference in the thickness between the big end and the handle of the arm body, the handle of the bending billet will be suspended when it is put into the pre forging die. During the pre forging, the transition between the handle and the big head will be folded. Due to the suspension of the handle of the bending billet, the metal flow in this part is too large.

Advantages of CNC machine tools over ordinary machine tools

The advantages of CNC machine tools are as follows:

  1. Processing efficiency, saving processing time.
  2. Work intensity. After the workers have finished programming, they can go to drink tea after the first piece is qualified.
  3. Reduce the number of waste products. As long as the first piece is qualified, the processed parts will generally be qualified.
  4. High safety, the farther the workers are from the processing equipment, the lower the probability of accidents.

For effective metal cutting, machining materials, cutting tools and cutting conditions are the three main factors. These determine the processing time, tool life and machining quality. Cutting conditions must be selected reasonably for economical and efficient processing methods.

The three elements of cutting conditions: cutting speed, feed and cutting depth directly cause damage. With the increase of cutting speed, the point temperature will rise, resulting in mechanical, chemical and thermal wear. If the cutting speed is increased by 20%, the tool life will be reduced by 1 / 2.

Back feed conditions and tool wear are kept to a minimum. But feeding behind, cutting temperature rise, wear. It is less than the effect of cutting speed. Cutting depth has no effect on cutting speed and feed, small cutting depth, but cutting material in hardened layer will also affect tool life.

According to the user’s processing material, hardness, cutting conditions, material selection, feed and cutting depth, the cutting speed is used.

Based on the selection of the most suitable process conditions, these factors are selected. Regular life and stable wear are the most ideal conditions.

However, in practice, the selection of tool life and tool wear, through machining size, surface quality, noise reduction, heat and so on. Under certain processing conditions, it is necessary to study CNC machining according to the actual situation. Difficult to machine materials such as stainless steel, heat-resistant alloy, can use coolant or choose a good rigid blade.

Reasonable selection of cutting tools

1。 Rough rotation, should choose high strength, good durability knife, in order to meet the large car turning, feedback.

2。 The essence of automobile is to select high precision, durable and good cutting tools to ensure the machining accuracy.

3。 Reduce the conversion time and knife convenience, should try to use machine knife and machine clip blade.

Select fixture

1。 General fixture should be selected to clamp workpiece as much as possible, and special fixture should be avoided;

2。 The coincidence of parts positioning datum reduces the positioning error.

Determine the processing route

Machining path is the part of tool path and direction relative to each other in the process of exponential control.

1。 It should be able to meet the requirements of machining accuracy and surface roughness;

2。 Shorten the processing route as far as possible and reduce the idle travel time of the tool.

Intelligent fault playback and fault simulation technology

Adaptive control technology of machining process: through monitoring the cutting force, power, current, voltage and other information of the spindle and feed motor in the process of machining, the traditional or modern algorithm is used to identify the force, wear and damage status of the cutting tool and the stability state of the machine tool, and adjust the processing parameters (spindle speed, feed speed) in real time according to these states In order to improve the machining accuracy, reduce the surface roughness and improve the safety of the equipment operation, the equipment is in the best operation state;

(2) Intelligent optimization and selection of processing parameters: the experience of process experts or technicians and the general and special laws of parts processing are used to construct the intelligent optimization and selector of processing parameters based on expert system or model. The optimized processing parameters can be obtained by using it, so as to improve the programming efficiency and processing level, and shorten the production preparation The purpose of time;

(3) Intelligent fault self diagnosis and self repair technology: according to the existing fault information, the application of modern intelligent methods to achieve rapid and accurate fault location;

(4) Intelligent fault playback and fault simulation technology: it can record all kinds of information of the system, replay and simulate all kinds of errors and accidents of CNC machine tools, so as to determine the causes of errors, find out solutions to problems, and accumulate production experience;

(5) Intelligent AC servo drive device: it can automatically identify the load and automatically adjust the parameters of the intelligent servo system, including intelligent Spindle AC drive device and intelligent feed servo device. The driving device can automatically identify the moment of inertia of the motor and load, and automatically optimize and adjust the parameters of the control system, so that the drive system can get the best operation;

(6) Intelligent 4m numerical control system: in the manufacturing process, the integration of processing and testing is an effective way to realize rapid manufacturing, rapid detection and rapid response. Measurement, modeling, manufacturing and machine operation (namely 4m) are integrated into one system to realize information sharing and promote measurement, modeling and addition Integration of tooling, clamping and operation.

  1. Open system

(1) Open to the future technology: because the software and hardware interfaces follow the recognized standard protocol, only a small amount of redesign and adjustment is needed, the new generation of general software and hardware resources may be adopted, absorbed and compatible by the existing system, which means that the development cost of the system will be greatly reduced, and the system performance and reliability will be continuously improved and will be in a long life cycle;

(2) Open to users’ special requirements: update products, expand functions, provide various combinations of hardware and software products to meet special application requirements;

(3) Establishment of numerical control standard: a new CNC system standard iso14649 (STEP-NC) is being researched and formulated internationally to provide a neutral mechanism independent of specific system, which can describe the unified data model of the whole product life cycle, so as to realize the standardization of product information in the whole manufacturing process and even in various industrial fields. The standardized programming language is not only convenient for users to use, but also reduces the labor consumption directly related to operation efficiency.

6-drive parallelization

Parallel motion machine tool overcomes the inherent defects of traditional machine tool series mechanism, such as high mass of moving parts, low system stiffness, tool can only feed along fixed guide rail, low degree of freedom of operation, and insufficient flexibility and mobility of equipment processing The length of the rod enables the platform supported by the bar system to obtain the corresponding degree of freedom movement, which can realize multi coordinate linkage NC machining, assembly and measurement functions, and can meet the processing of complex special parts. It has the advantages of high modularity, light weight and fast speed of modern robot.

As a new type of processing equipment, parallel machine tool has become an important research direction of current machine tool technology. It has been highly valued by the international machine tool industry. It is considered as “the most significant progress in the machine tool industry since the invention of numerical control technology” and “a new algebraic control processing equipment in the 21st century”.

  1. Extreme (large scale and miniaturization)

The development of national defense, aviation and aerospace and the large-scale of energy and other basic industrial equipment need the support of large-scale and good performance CNC machine tools. Ultra precision machining technology and micro nano technology are strategic technologies in the 21st century, and new manufacturing processes and equipment that can adapt to micro size and micro nano machining accuracy need to be developed. Therefore, the demand for micro machine tools, including micro cutting (turning, milling, grinding) machines, micro electro machining machines, micro laser machining machines and micro presses, is gradually increasing.

  1. Information exchange networking

For the enterprises facing fierce competition, it is very important to make CNC machine tools have bidirectional and high-speed network communication function, so as to ensure the smooth flow of information among various departments in the workshop. It can not only realize the sharing of network resources, but also realize the remote monitoring, control, training, teaching and management of CNC machine tools, but also realize the digital service of CNC equipment (remote diagnosis and maintenance of CNC machine tools, etc.). For example, Japan’s Mazak company has launched a new generation of processing center equipped with an external device called e-tower, including computers, mobile phones, external and internal cameras, which can realize the communication failure alarm of voice, graphics, video and text
