What is mechanical precision machining
Publisher: Webmaster | release time:2013/8/16 |read:2898Times
    Mechanical precision machining also known as Precision machining, it is different from ordinary machining, and requires higher precision than ordinary mechanical machining He mainly uses processing machinery to change the external dimensions of the workpiece. According to the temperature state of the workpiece to be processed, it can be divided into two types, cold processing and hot processing. When processing at room temperature without causing chemical and physical changes to the workpiece, this is called cold working. Processing at a temperature above or below room temperature will cause chemical or physical changes to the workpiece. This is called hot working. According to the difference in processing methods, cold working can be divided into cutting and pressure processing. This type of processing requires higher equipment used in processing, and even requires auxiliary oil. This type mainly produces some small workpieces. The common heat processing is mainly heat treatment, forging, casting and welding, etc., this type mainly does some large workpieces.
