What are the machining requirements for precision parts?

(1) Generally speaking, due to the different roughness and accuracy of the parts due to the cutting volume, heating and cutting force of the parts, in order to ensure the machining accuracy of the parts, rough parts and precision mechanical parts must be processed separately. If the initial machining and precision machining continue, the precision of the precision machined parts will be lost due to different stresses.

(2) Rationalization of equipment selection. The processing of rough parts does not require high machining accuracy, but it is mainly to reduce the machining allowance, so precision machining must be a very high-precision machine tool. The heat treatment process is usually organized on the processing road of precision parts. The direction of the heat treatment process is as follows: In order to ensure the cutting characteristics of the metal, such as annealing, quenching, quality adjustment, etc., it is generally carried out before processing.

(3) Generally speaking, all precision parts have heat treatment methods, which can improve the cutting characteristics of metals. The processing and manufacturing of precision parts not only require the accuracy and stability of machine tools and the accuracy of tools and fixtures, but also require precision measuring instruments for correction and measurement. Some in the process, some after testing.

The process of mass hot forging and temperature calcination of two forgings is a process that directly changes the appearance of the raw material to a semi-specific product or a different product. This process is called the technological process, and it is also the standard of the parts processing process. The production process of precision parts is more complicated. The processing technology specification of precision parts can be divided into forging, forging, stamping, welding, heat treatment, processing, installation, etc. The production process of precision parts refers to the general term of the entire parts of the CNC machining and machine installation process. Other processes such as cleaning, inspection, equipment maintenance, oil seals, etc. change the surface characteristics of raw materials or semi-finished products. This process is called CNC machining. The corresponding tool middle orbit has different conversion methods, and the precision part system has linear and circular interpolation functions.
