What are the machining requirements for precision parts?
(1) In general, due to the different roughness and accuracy of the parts due to the cutting amount, heating and cutting force of the parts, in order to ensure the processing 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 mainly to reduce the processing allowance, so precision machining must be a very high-precision machine tool. The heat treatment process is usually organized on the machining 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) In general, all precision parts have heat treatment methods that can improve the cutting characteristics of the metal. The machining and manufacturing of precision parts not only requires the accuracy and stability of the machine tool and the accuracy of its tools and fixtures, but also requires precision measuring instruments for correction and measurement. Some during processing, some after testing.
Mass hot forging The mass hot forging forming and temperature calcination process of two forgings is the process of directly changing the appearance of the raw material to a semi-specific product or a different product. This process is called the process and is also the standard for parts processing. The production process of precision parts is more complex. Precision parts processing specifications can be divided into forging, forging, stamping, welding, heat treatment, processing, installation, etc. The production process of precision parts refers to the general term for the CNC machining and machine installation process of the entire part, and other processes such as cleaning, inspection, equipment maintenance, and oil seals change the surface characteristics of raw materials or semi-finished products. This process is called numerical control machining. The corresponding tool intermediate track has different conversion modes, and the precision parts system has linear and circular interpolation functions.
