How to improve the reliability of CNC machine tools

It is well known that the reliability of CNC machine tools can be greatly improved by using high performance and high reliability NUMERICAL control system, servo drive device and high quality supporting components in machine tool design. Because of the same type of CNC machine tool is also the same type of CNC system, so domestic machine tools in precision and performance compared with imported CNC machine tools, the gap is not too big, but also has a certain advantage in after-sales service and price, but both in the mind of users in the credibility is not the same. Here is how to improve the reliability of CNC machine tools.

1. Demonstrate the feasibility of product design scheme through process test

On the basis of in-depth understanding of user needs, first of all, the key technology involved in user needs - "deep hole processing technology" process test, through the process test to demonstrate the feasibility of product design scheme, to ensure that the designed products can meet user needs.

2. Adopt modular components with mature technology

The structure design of multi-station CNC combined machine tool adopts modular components verified by mass production of our company, such as CNC slide table using linear rolling guide rail, small drilling power head, high precision CNC turntable, etc.

3. Carefully designed logic control program to enhance diagnostic function

Attach importance to the design of nc machine tool logic control program, in addition to carefully design the necessary logical control program, safety interlock function, but also the application of PLC information function, alarm function, design necessary operation tips and diagnostic information, enhance the diagnostic function of NC machine tool, easy to guide the user operation and maintenance.

4. Use the functions of the NUMERICAL control system correctly

High performance NUMERICAL control system in the application, because of incorrect parameter setting, unreasonable logic control program often make numerical control machine tools with problems out of the factory, in the user use only found the existence of problems, affecting the reputation of the product. For example, when the pitch error compensation function of the system is used to correct the positioning accuracy of CNC turntable, the incorrect parameter setting will make the turntable rotate in the same direction, but bring more and more errors; Incorrect setting of acceleration and deceleration time constant will cause impact on the transmission mechanism of machine tools.

5. Sum up experience and lessons

Analyze the quality information from previous production of modular machine tools and after-sales service feedback, and put forward improvement requirements for protection, wiring and appearance of machine tools.
