What is the order of precision CNC machining?

  1. The measuring tool can detect the drawing requirements required by the customer, and is used to detect and process the data of the workpiece. Our inspection tools are divided into measurement and quality inspection during precision machining. If you need to measure whether a workpiece meet the accuracy requirements of the process during machining, you need to wait until the workpiece is completely stopped and measured. To avoid the vibration and wear of the workpiece, the measuring surface of the measuring tool is generally operated by specialized QA personnel, and there is no need to describe the use of the measuring tool too much.

  2. The arrangement of the heat treatment process is to upgrade the cutting performance of the metal, which is usually carried out before machining. The time to eliminate internal stress is generally after rough machining and before finishing. In order to improve the mechanical properties of parts. Carburizing, quenching, tempering, etc., are generally carried out after mechanical processing.

  3. The measure to ensure the precision of precision machining is to carry out rough machining and finishing respectively. Due to rough machining, a large number of workpieces are subjected to cutting force, clamping force, and heat generation. It is easy to cause the problem of surface hardening and large internal stress in the workpiece. Therefore, for parts with high machining accuracy, low temperature annealing or aging treatment should be carried out after rough machining and before finishing to eliminate internal stress. Roughing and finishing on different machine tools can not only give full play to the performance of the equipment, but also extend the service life of precision machine tools.

  4. The previous process of precision machining cannot affect the positioning and clamping of the next process. It also requires comprehensive thinking if there are general fine parts processing procedures in the middle. For the multiple processes that stop in the same device, the process should first be arranged with less damage to the rigidity of the workpiece. The tool centralized sorting method is to divide the processes according to the tools used, and use the same tool to machine all the parts that can be realized on the part. Use the second and third knives to realize other parts that can be achieved. This can reduce the number of tool changes, shorten the idle time, and reduce positioning errors.

To sum up, so professional, LJZ CNC machining can be your best choice!
