What does machining include?

Machining refers to a process in which the shape and size of the workpiece are changed mainly by connecting and unloading. According to different conditions, machining is divided into many kinds. In general, we divide mechanical processing into cold processing and hot processing in accordance with the temperature state of the processed workpiece.


Cold working is processing that does not cause chemical reactions or changes in the image of the workpiece under normal temperature conditions. The thermal processing is processing at higher or lower than normal temperature, causing chemical or phase changes of the workpiece.


The development of machining


With the development of science and technology, companies engaged in machining today tend to be more high-precision, multi-variety, small-batch, low-cost, short-cycle and complex machining, and machinery and equipment are also thinking about the development of numerical control. Compound machining is an important technological development direction of CNC machine tools. The composite function enables the CNC machine tool to significantly increase the production speed of the finished workpiece, which can greatly eliminate the transportation, clamping and waiting time during the hashing process, greatly shorten the processing cycle and reduce the number of products in the processing workshop. The workpiece is only clamped and positioned once on the machine tool, which not only reduces the processing auxiliary time, but also improves the processing accuracy of the workpiece.
