Decomposition of machining accuracy and heat treatment technology of Shenzhen automatic lathe

        Shenzhen automatic lathe processing can also be called mechanical processing knowledge. Shenzhen Huazheng Precision Co., Ltd. has more than 10 years of experience in the hardware industry. Here is a brief introduction. You may have heard of many different things, but there will always be something lost. Therefore, it is necessary to compensate and update knowledge, so that we can grasp more updated knowledge in time, so that we can fully and carefully understand this aspect of mechanical lathe processing.

       Preparatory heat treatment: Its purpose is to improve mechanical properties and eliminate internal stress in order to prepare for final heat treatment, generally including annealing, normalizing, quenching and tempering and aging treatment. Preliminary heat treatment is generally performed after rough machining. After all, heat treatment: its purpose is to improve the hardness and wear resistance of parts, including quenching, carburizing, nitriding and other skills, which are generally carried out after semi-finishing and before finishing.

The precision of mechanical automatic lathe processing

      The accuracy of machining is mainly reflected in the following aspects, which are standard accuracy, geometric shape accuracy and mutual orientation accuracy, among which geometric shape accuracy includes roundness, straightness and flatness, etc., mutual orientation accuracy includes parallelism, perpendicularity degree and coaxiality.

What are the methods to obtain machining accuracy?

      Standard accuracy: There are mainly trial cutting method, adjustment method, standard method and automatic control method.

Geometric accuracy: There are mainly orbital method, forming method and generation method.

Mutual orientation accuracy: There are mainly direct installation method, alignment installation method and fixture installation method.
