At the same time, the parts processed by high-precision lathes are divided into cold processing and hot processing according to their temperature conditions. Generally, it is processed at room temperature, and it does not cause chemical or phase transformation of the workpiece, which is called cold processing. Generally, processing higher than or lower than room temperature will cause chemical or phase transformation of the workpiece, which is called thermal processing. According to the...

CNC machining is an extremely common processing method used in the production of industrial equipment, and has been widely used in many companies. In the whole process of processing, the production is generally carried out according to the actual stainless steel plate parts, so in the production process, do you know the whole process of CNC machining? Here is a simple analysis for you, mainly divided into six processes. 1. Product positioning Before producing and machining parts, companies...

, Precision hardware parts processing In order to better ensure the processing accuracy of machine parts, the processing of rough and fine mechanical parts is better carried out separately. Due to the large amount of drilling during the processing of rough mechanical parts, the cutting speed and clamping force of the product workpiece are large, and the calorific value is large, and the machining surface of its mechanical parts has a relatively obvious processing hardening condition, and the...

Precision hardware parts processing effectively uses machinery and equipment. The machining of rough machine equipment parts is mainly to remove most of the machining capacity, and does not require high machining accuracy of mechanical parts. Therefore, rough machining should be carried out on equipment with relatively high output power and low precision, while the finishing process is It needs to be processed with a higher precision CNC lathe. Roughing and finishing are processed on different...

Precision hardware parts processing In the processing style of machine equipment parts, there is often a heat treatment process. The arrangement of the process parts of the heat treatment process is as follows: In order to improve the drilling processing characteristics of metal materials, such as quenching, quenching, heat treatment, etc., it is generally arranged before the machining of mechanical parts. In order to remove thermal stress, such as quenching and tempering treatment, quenching...

1. The purpose of precision machining is to remove the thermal stress formed during the production and manufacture of the blank, and to prepare for the final heat treatment process. Generally, it is arranged before processing, which can improve the turning production and processing characteristics of the material and is beneficial to remove residual thermal stress.2. The final heat treatment process should generally be arranged before and after the initial processing and finishing. For example,...
