What is mechanical precision machining?

- Aug 01, 2017-

Mechanical precision machining, also known as precision machining, he is different from ordinary mechanical processing, to be more accurate than ordinary mechanical processing requirements, he is mainly using processing machinery to change the shape of the workpiece.

According to the processed workpiece temperature state can be divided into two kinds, cold processing and hot processing: processing at room temperature but not causing the chemical and physical changes of the workpiece when this is called cold processing, in the higher or lower than normal temperature conditions of processing, but also cause the workpiece chemical or physical changes, which is called hot processing.

Cold processing in accordance with the different processing methods can be divided into cutting and pressure processing, this type of processing for processing equipment used in high requirements, even need to auxiliary oil, such as the main production of some small pieces of work more, and hot processing is commonly used mainly heat treatment, forging, casting and welding, and so on, this kind of main do some large workpiece more.
