6. Maximum machining size:

The maximum machining size is purchased according to your needs. At present, most machine tools can meet your needs, except for some single-axis or double-axis machine tools for samples or test fixtures.

7. Operating system and control system:

At present, many machine tools use the general windows operating system, which has a very friendly interface. Some also use Chinese, which is easier to learn and operate. However, its disadvantages are that the stability of computer viruses is slightly poor and management is difficult. Some use industrial systems or UNIX systems. The advantages of this system are good stability, not easy to fail, and convenient management. But the operation interface is in English, and the operation is a little slow. The latter is recommended from the perspective of process and equipment maintenance.

8. Tool management system:

In the past, there were few machine tools, some of which had only eight tool holders. Now, most of the NC machine tools can be placed with hundreds of drill bits, and some systems also have automatic detection of broken drill bits and diameter detection length, and radial runout systems. When selecting the type, it should be noted that most of the drill bits of the NC machine are placed in the front of the table, which has a disadvantage, If the circuit board processed during work jumps out due to fixing problems, it is easy to break all drill bits, including drill bit clamps. Some drill bit fixtures are designed above the machine tool, such as some machine tools produced in Switzerland, which will not cause this problem. The sensitivity of the detection mechanism is too high and too low, which is not good for the machine tool. Generally, it is better to be a little lower.

9. Purchase of light ruler system:

At present, most of the measurement systems of CNC machine tools use a light ruler as the position and accuracy measurement feedback system, and some also use a magnetic ruler. The system stability and resolution of using a light ruler are high. Because the reading head of the light ruler has no contact friction with the ruler body, it has a long service life, but at ordinary times, it is necessary to keep the equipment clean and minimize dust pollution.

10. Dust collection system:

If the company does not have a central dust collection system and uses an ordinary industrial dust collector as a supporting device, it should pay attention that the power of the dust collector should be large, preferably 30-50% higher than the power required by the original design, because the power will drop a lot due to the blockage of the filter in the actual use process. Secondly, the powder bag of the dust collector should have sufficient capacity. If the capacity is too small, workers will often stop working to deal with the dust, which will affect the production efficiency.

11. Protection system:

It refers to the protection system designed to prevent accidental injury accidents and accidents on the equipment software and equipment itself, such as grating protection, infrared protection, air switch, etc. for example, infrared protection, etc. should be designed reasonably, and some protection designs are not very convenient for maintenance. So we should make a comprehensive balance.
