CNC NC machine tool is a kind of high and new technology which combines the advanced technology such as computer technology, automatic control technology, automatic detection technology and precision mechanical design and manufacture. It is a typical mechanical and electrical integration product with high technology density and high automation.
Compared with ordinary machine tools, NC machine tool not only has the characteristics of high precision of parts processing, high production efficiency and high automation of product quality, but also can complete the parts processing of complex surface which is difficult to complete or cannot be machined by ordinary machine tools. Therefore, the position of digital control machine tool in the machinery manufacturing industry appears to appear. It is becoming more and more important. We can even say this: in the machinery manufacturing industry, the grade and quantity of CNC machine tools is an important symbol to reflect the manufacturing capability of an enterprise. In enterprise production, CNC machine tools can achieve the goal of high processing precision, stable product quality and higher production efficiency. This not only depends on the accuracy and performance of the machine tool itself, but also to a large extent, it is closely related to the operator in the production of CNC machine tools in the maintenance and use of the machine. At the same time, we should also notice that the concept of the maintenance of CNC machine tools can not simply understand that the mechanical parts and other parts of the CNC system or the CNC machine tools are only dependent on the maintenance personnel how to remove the faults and repair them in time, so that the CNC machine bed can be put into use as soon as possible. This should include proper use and routine maintenance. In the two aspects, only by insisting on the daily maintenance of the machine tools can we prolong the service life of the components, prolong the wear cycle of the mechanical parts, prevent the occurrence of accidental malpractice, and strive for the long and stable work of the machine tools, and make full use of the machining advantages of the machine tools to achieve the numerical control machine. The technical performance of the bed ensures the normal work of the CNC machine tools. Therefore, it is very important to maintain and maintain the CNC machine tool for the operator of the CNC machine tool or the maintenance personnel of the CNC machine tools. We must pay great attention to it.

Machining center has high machining accuracy and stable machining quality.
It can carry out multi coordinate linkage and process complex parts.
When machining parts change, it is generally necessary to change the NC program and save production preparation time.
The machine tool itself has high accuracy and rigidity, and can choose the favorable processing amount and high productivity (usually 3~5 times of ordinary machine tools).
The machine is highly automated and can reduce labor intensity.
The requirements for the quality of the operators are high, and the technical requirements for the maintenance personnel are even higher.

Machining center is a highly automated multi-function CNC machine tool with tool magazine and automatic tool changer. After one clip is installed on the machining center, the workpiece can be processed on more than two surfaces, and there are many kinds of knife changing or cutting tool function, thus the production efficiency is greatly improved.
Machining centers are divided into two categories: boring, milling and turning according to their processing procedures. According to the number of control axes, machining centers can be divided into three axis, four axis and five axis machining centers.

For the general machine tool CNC machining center, the NC machine has high machining accuracy, good dimensional stability, low labor intensity, and convenient for modern management. However, because of improper operation or programming errors, the tool or tool holder is easily hit on the workpiece or machine tool. The light person will break the tool and the machined parts. The heavy person will damage the machine parts, so that the machining accuracy of the machine tool will be lost and even the personal accident will be caused. Therefore, from the point of view of maintaining accuracy, it is not allowed to collide with the machine tool or workpiece in the use of NC machine tools. The following causes of the collision knife are summarized and analyzed.
As the CNC machining center is locked by software, when the automatic operation button is pressed, it is not intuitively locked in the simulation interface when the automatic operation button is pressed. In simulation, there is no tool setting. If the machine is not locked, it is easy to hit the knife. So before the simulation processing, we should confirm whether the machine is locked or not. Forget to turn off the empty operation switch when processing. In the process of program simulation, the idle operation switch is often opened to save time. Empty operation refers to the movement of all moving axes of machine tools at G00 speed. If the switch is not turned off in the processing time and space, the machine tool ignores the given feed speed and runs at G00 speed, resulting in an accident of cutting and hitting the machine tool. There is no return to the test point after the air operation simulation. When the program is checked, the machine tool is locked, and the tool relative to the workpiece is processed in the simulated operation (the absolute coordinates and the relative coordinates are changed). The coordinates of the machine are not in conformity with the actual position, and the method of returning the reference point should be used to ensure the zero point coordinates of the machine and the absolute and relative coordinates. If the problem is not found after checking the program, the machining operation will result in the collision of the tool. The direction of the override is not right.
When the machine tool overruns, it should hold down the over lift button and move it in the opposite direction by manual or manual way, that is, it can be eliminated. However, if the direction of release is reversed, it will cause damage to the machine tool. Because the overshoot protection of the machine will not work when the overload is lifted, and the travel switch of the override protection is at the end of the journey. At this time, it is possible to cause the worktable to continue to move in the direction of overshoot, eventually leading to failure of the lead screw, resulting in damage to the machine tool. The specified line running time mark position is unsuitable. When a specified row is running, it often starts down from the cursor position. For the lathe, it is necessary to call the tool bias of the tool used. If the tool is not called, the tool in the running section may not be the tool required, and it is very likely to cause the tool accident because of the different tool. Of course, in the machining center and CNC milling machine, we must first invoke the coordinate system, such as G54 and the length compensation value of the knife. Because each knife’s length compensation value is different, if not invoked, it may cause collision knife.
1.CNC machining center CNC machine tool, as a high precision machine tool, is very necessary to prevent collision. It requires the operator to develop the habit of careful careful and careful, to operate the machine tool in the correct way, and to reduce the phenomenon of machine tool crashing. With the development of technology, the advanced technologies such as tool damage detection, machine tool collision detection and machine tool adaptive processing have appeared in the process of processing, which can better protect CNC machine tools.

The important role of the tool point in NC machining and the way to determine the tool setting point. The starting point of the program is the movement of the tool relative to the workpiece during NC machining. In NC programming, the following points should be considered when choosing tool points.
1. The non program programming is simple.
2, the error caused by the processing is minimal.
3. It is easy to check in the process of processing.
4, the tool point is easy to find on the CNC machine tool.
5, it is easy to calculate the coordinate value of the knife point.
6, try to make the process of cutting or retracting the shortest path, and easy to change the knife.
7, try to coincide with the design datum or positioning datum of parts. For example, the location of holes with holes is better as the center hole of the hole, so the positioning error can be reduced. The tool point can be located on the machined parts, and can also be located on the auxiliary datum of the fixture, but it must have a certain dimension relationship with the positioning datum of the parts, so as to ensure the relationship between the machine tool coordinate system and the workpiece coordinate system.

From the overall installation structure of CNC CNC system, there are two kinds of integral structure and split structure.

The so-called monolithic structure is the CRT and MDI panel, operation panel and function module board composed of circuit boards installed in the same box. The advantage of this method is that it is compact and easy to install, but sometimes it may cause some signal connections to be too long. The split structure usually makes the CRT and the MDI panel, the operation panel and so on as a component, and the circuit board composed of the functional modules is installed in a chassis, which is connected by a wire or fiber. Many CNC machine tools take the operating panel as a single part, which is due to the different requirements of the machine tool, the operation panel should be changed accordingly, and the composition and body style is beneficial to the replacement and installation.

The installation of CNC operation panel on machine tools includes hanging type, bedside type, control cabinet type, control desk type and so on.

From the structural characteristics of the CNC circuit board, there are two common structures, that is, large panel structure and modular structure. The characteristic of big board structure is that a system usually has a big board, it is called the motherboard. The main board is equipped with a master CPU and a position control circuit for each shaft. Other related sub boards, such as ROM board, part program memory board and PLC board, are inserted directly on the main board to form the core part of the CNC system. It can be seen that the large plate has compact structure, small size, high reliability, low price, high performance / price ratio, and easy to integrate design of machine tools. Although the large plate structure has the above advantages, its hardware function is not easy to change and is not conducive to the organization of production.

Another high flexible structure is the open system structure of bus modularization. Its characteristic is to make CPU, memory, input and output control into plug-in board (called hardware module), and even CPU, memory, input and output control to form an independent microcomputer level hardware module, and the corresponding software is also a module knot. Structure, solidified in the hardware module. Hardware and software modules form a specific functional unit, which is called function module. Functional modules have well-defined interfaces, interfaces are fixed, become factory standards or industrial standards, and they can exchange information with each other. Therefore, the CNC system can be made up of building blocks, which makes the design simple, with good adaptability and expansibility, short trial production period, convenient adjustment and maintenance, and high efficiency.

According to the CPU and structure used in CNC system, the hardware structure of CNC system is generally divided into two categories: single CPU and multi CPU structure. The initial CNC system and some current economic CNC systems use a single CPU structure, and the multi CPU structure can meet the requirements of high speed, high machining precision and many complex functions of CNC machine tools. It also adapts to the need of integration into FMS and CIMS operation, thus getting the rapid development. It reflects the new water of the CNC system today. Flat.

Joint bearing connecting rod

The joint bearing can bear a large load. According to its different type and structure, it can bear the combined load of radial load, axial load or radial and axial coexistence. Since the composite material is embedded on the outer spherical surface of the inner ring, the bearing can produce self lubrication in operation. It is generally used for low speed swinging motion and low speed rotation. It can also be tilted in a certain angle range. When the abutment axis and the axle housing hole are not concentric, they can still work normally. Self lubricating joint bearings are used in water conservancy, professional machinery and other industries.

Joint bearings are widely used in engineering hydraulic cylinders, forging machine tools, construction machinery, automation equipment, automotive shock absorber, water conservancy machinery and other industries. Spherical plain bearings are spherical bearings. The basic type consists of inner and outer rings with spherical sliding spherical contact surfaces. According to its structure and type, it can bear radial load, axial load, or radial load.
Because the spherical sliding contact area of the joint bearing is large and the inclined angle is large, but also because most joint bearings have taken special processing methods, such as surface phosphating, galvanizing, chromium plating or outer sliding surface lining, padding, spraying and so on, so it has great load capacity and impact resistance, and has corrosion resistance and wear resistance. Loss, self aligning, lubrication, or self lubrication, no dirt contamination, even if misplaced. Therefore, the joint bearings are widely used in low speed swing motion, tilt motion and rotation motion.
