How to correct with cutting fluid in CNC machining

There are two kinds of cutting fluids for CNC machining of product parts: Oil-based cutting fluid and water-based cutting fluid. Precision parts processing is a kind of accessories widely used in automobile, communication, medical treatment, clocks, mobile phones, computers and other industries. Different from ordinary parts, precision parts are more precise and more suitable for some industries with high requirements for precision. Micropore processing less than 2 nm is called micropore. The pore size of some catalysts is usually described. Micropore processing is difficult, especially for micropores with a diameter of less than 1mm. However, many mechanical products have this microporous structure. CNC machining feed machining route refers to the turning tool from the tool setting point (or the fixed origin of the machine tool) starts to move until it returns to this point and ends the processing program, including the cutting path and non cutting empty stroke paths such as tool cut in and cut out. The cutting fluid used for CNC processing of product parts can be divided into cutting oil, emulsion, semi synthetic fluid and synthetic fluid, cutting oil, emulsion (sometimes referred to as soapy water) and synthetic fluid (commonly known as environment-friendly fluid), synthetic fluid may be commonly used, but little is known about how to select cutting fluid in the machining process. Let’s look at the advantages and disadvantages of each cutting fluid.

  1. Cutting oil for CNC machining of product parts. Very high physical lubrication B is suitable for low speed, less cutting allowance C surface finish and provides excellent service.
  2. CNC processing emulsion is used for product parts: advantages: multi metals have good safety and good lubricity. The advantages of this method are: good rust prevention, easy sewage treatment, disadvantages: increase the dosage; emulsify the sewage oil at the same time. The odor is not well controlled. The equipment is very dirty. The stability of hard water is very poor. The filtration is poor and the mixing is poor
  3. Semi synthetic liquid is used for CNC processing of product parts: advantages

1。 Cooling effect is better than emulsification effect.

2。 Better rust prevention

3。 Cleaner than emulsion.

4。 Better filtration performance

5。 More suitable for hard water and dirty oil. More suitable for hard water and dirty oil. The antibacterial effect is better than emulsion. Disadvantages:

1。 Blisters easily in soft water.

2。 Oil resistance is worse than synthetic liquid.

3。 At high concentrations, there may be a tendency to skin allergy

4。 Synthetic fluid used in CNC processing of product parts: advantages:

1。 Very clean.

2。 It doesn’t smell.

3。 Senior operator acceptance

4。 Low consumption (12-20 weeks)

5。 Excellent cooling performance. Figure 6. Completely refuse to spill oil. Low bubble 8. Long service life. Very good filtration / rapid sedimentation performance, disadvantages:

1。 Low physical lubrication

2。 Sewage treatment is difficult. A sticky residue, especially in hard water. Incompatible with emulsion. React with polycarbonate. It may damage the paint surface of the machine. Through the description of the cutting fluid used for CNC machining of the above various product parts, we can better understand them and be more clear about what kind of cutting fluid to choose.


Machining accuracy of CNC computer gong

In the machining industry, there are often high-precision machining of mechanical parts, which should be completed by selecting suitable machine tools and equipment. Let’s take a look at the machining accuracy of high-speed CNC computer gongs?

CNC computer gong is actually CNC machining center, which is an automatic machine tool controlled by program. The control system can logically process the program with control code or other symbolic instructions, decode it through the computer, so as to enable the machine tool to perform the specified action, and process the raw materials into semi-finished products or finished mechanical parts through tool cutting. CNC machining is completely controlled by computer and completed by process programming according to the drawing of mechanical parts. CNC machine tool itself has high precision. Generally, the spindle speed is 8000 / r.p.m, the spindle of high-speed machine can reach 10000-15000 / r.p.m, the part plane precision can reach 0.002-0.005mm, and the hole precision can be controlled between 0.003-0.005mm. In case of complex machining of mechanical parts, different process methods are selected to complete the machining accuracy.

The above is about the machining accuracy of CNC computer gongs. Thank you for sharing!


What tools are used for CNC processing aluminum

In the machining process of mechanical parts, the appropriate selection of cutting tools can be directly related to production efficiency and ultra-high machining cost! Therefore, it is also a skill in the machining industry to choose what materials to process and what tools to use. Let’s take a look at what kind of cutting tools are used for metal and aluminum processing?

Aluminum, also known as aluminum alloy in the machining industry, is one of the most common and important metal materials. In the mechanical equipment manufacturing industry, almost 60% of the mechanical equipment spare parts are processed with aluminum, especially in lithium battery equipment, laser equipment, non-standard automation equipment, optical industry and electronic technology. More than 80% of the spare parts of this equipment are replaced with aluminum. In machining aluminum is also the most contact!

For aluminum processing, many people may say that it is OK to use ordinary white steel tools. It is also applicable if the cost is not high, which is really good. However, our production efficiency can’t be improved. It’s easy to wear when processing with white steel tools, and the tools will often break, especially small ones. This is not cost-effective. The tool we want to say is not two edge or four edge. It is a three edge tool. Aluminum cutting has unique advantages. Compared with ordinary tools, it continuously improves the working efficiency, is not easy to wear and break, and the dimensional accuracy control is also guaranteed. In the machining industry, it is called aluminum special tool, which is the best choice for aluminum processing!

The above is a brief description of what kind of cutting tools are used for machining aluminum. Thank you for your attention!
