as a big manufacturing country, the processing of machinery and equipment has become an important process, whether it is a precision part or a large machine, it is necessary to process tools such as knife cutting, CNC boring machine and other tools to get the desired finished product.

    Hangzhou Yu Chen Machinery Co., Ltd. undertake all kinds of mechanical processing, whether it is fourth axis, fifth weeks, five sides, auto parts and spare parts can find us. A five - face machining center, after years of work, may often have zero drift in the machining coordinate system, which seriously affects the processing quality and stability of the workpiece.

    the reason for analysis may be that the geometric accuracy of the machine tool needs to be compensated. However, the geometric accuracy of the machine tool is up to the standard by the laser detector. Further analysis of the cause may be caused by temperature and environment. After field verification, the size error, position error and shape error of the workpiece finished when the workpiece is processed, the workpiece processing begins to stabilize after the machine is open about 1H. This fully shows that the machine is in the state of the refrigerator, and the temperature of the oil does not reach the normal state. The thermal expansion of the machine is not fully released, which affects the accuracy of the workpiece and the stability of the machining.

    solution:

(1) explain to the operator why the machine is preheated before working every day. Only when it is fully preheated can the quality of machine tool be guaranteed and the production efficiency can be improved.

(2) compiling the hot machine macro program for the machine tool. Daily heat engine 0.5h, and the handling procedures. This will greatly help improve production efficiency and ensure product quality.
