What are the processing requirements for precision parts

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

(2) Rationalization of equipment selection. The machining of rough parts does not require high machining accuracy, but mainly to reduce machining allowance, so precision machining must be a very high-precision machine tool. The heat treatment process is usually organized on the processing path 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 that can improve the cutting characteristics of the metal. The processing and manufacturing of precision parts not only require the accuracy and stability of machine tools, as well as the accuracy of tools and fixtures, but also require precision measuring instruments for calibration and measurement. Some are during processing, while others are after testing

The mass hot forging forming and temperature calcination process of two forgings is the process of directly changing the appearance of raw materials into semi specific products or different products. This process is called a process and is also the standard for part processing. The production process of precision parts is more complex. The processing process specifications for precision parts can be divided into forging, forging, stamping, welding, heat treatment, processing, installation, etc. The production process of precision parts refers to the overall process of CNC machining and machine installation of the entire part. 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 intermediate tracks have different conversion methods, and the precision part system has linear and circular interpolation functions
