How to deal with precision machining?

In order to ensure the precision of precision machining. Many workpieces are subjected to cutting force, high clamping force, and high calorific value, so rough machining and finishing should be carried out separately. Because of rough machining. It is very easy to cause the surface layer to harden, and there is a great internal stress inside the workpiece. If the finishing and roughing are continuous finishing, the precision of the fine parts will be spread again with the ground stress, and it will quickly be lost. For some parts with high machining accuracy. After rough machining and before finishing machining, ultra-low temperature quenching or aging treatment should be carried out to remove internal stress.

　　The main process of roughing is to cut off most of the machining allowance, and the roughing CNC lathe only needs high-power, low-precision production and processing. Finishing requires a finer CNC lathe. For rough and finishing machining on different CNC lathes, higher machining accuracy is not specified. thus. It can not only make full use of the characteristics of machinery and equipment, but also increase the service life of precision machinery.
　　 Heat treatment is often required during machining. The distribution of the heat treatment process is as follows: in order to improve the cutting performance of the metal. It is usually carried out before machining. In order to remove the internal stress, such as quenching, quenching, heat treatment and so on. Such as aging treatment and quenching and tempering treatment, etc., generally after rough machining, before finishing. In order to improve the physical properties of the parts, nitriding, heat treatment, quenching, etc. are generally carried out after mechanical processing. If there is deformation after heat treatment, the final production process must be allocated.
　　 The above explained is the processing method of precision machining, I hope it will be helpful to you after reading it. If you want to know more about precision machining related information, welcome to consult and we will be happy to help you Provide quality service!
