How to control the accuracy of special material processing?

To control the accuracy of special material processing, it is necessary to do a good job in process selection, equipment accuracy guarantee, tool and abrasive fitting, real-time monitoring and adjustment, and personnel skills and experience

Process selection

The appropriate processing technology should be selected according to the characteristics of special materials. For example, for ceramic materials with high hardness, using special processing technologies such as EDM and laser processing may be easier to ensure accuracy than traditional cutting, because it can remove materials in a non-contact or micro contact manner, reducing the impact of material cracking on accuracy.

Equipment accuracy assurance

It is very important to use high-precision processing equipment. High precision CNC machine tools and grinding machines have accurate motion control systems and high positioning accuracy. Like some nano precision machining centers, they can control the dimensional error in a very small range when processing special materials, laying the foundation for ensuring accuracy.

Tool and abrasive fitting

Special materials often have strict requirements for cutting tools and abrasives. For example, when machining titanium alloy, it is necessary to select tools made of cemented carbide, ceramics and other materials, and to ensure the sharpness and wear resistance of the cutting edge. A suitable tool can stably remove the material in the cutting process, so as to avoid the accuracy deviation caused by rapid tool wear.

Real time monitoring and adjustment

In the process of processing, coordinate measuring instruments and other precision detection equipment are used for real-time monitoring, and the accuracy indicators such as size and shape are detected at regular intervals or process nodes. Once deviations are found, the processing parameters are adjusted in time to ensure that the processing accuracy is always within the controllable range.

Personnel skills and experience

The operator shall be familiar with the processing characteristics of special materials, have rich processing experience, and be able to flexibly adjust the process parameters, feed amount, etc. according to the actual performance of materials in processing, so as to ensure the processing accuracy to the greatest extent.
