How to ensure the processing quality of precision parts?
Precision parts machining is a process of using machining machinery to change the overall dimensions or performance of precision parts.
In the process of precision parts processing, the factory should not only ensure the quality, but also carefully maintain the external beauty and magnanimity. In order to better ensure that the precision parts are not corroded by sweat, gas and other components, they are always in the factory state and extend the service life. When parts are packaged after release, a separate sealed packaging method must be used. At the same time, gasoline or ethanol must be used for scrubbing. Gloves must be worn for work and drying, and then cotton wool shall be used for protection.
In the processing of various mechanical parts, due to the deep groove, small overall width, small size tolerance range, the balance screw is difficult to process, difficult to process, easy to produce scratches, and difficult to process. To ensure the size. From the perspective of traditional processing technology, combined with the current measuring tools, the mold shell can be polished and grooved before processing; The balance screw and the die sleeve are processed at the same time, and there is a small gap between the die sleeve and the product workpiece, which not only improves the stiffness of the slotting, reduces the probability of deformation, but also makes the precision of the balance screw higher
This standard refers to the points, lines and faces used to clarify the geometric correlation between the geometric factors of the manufacturing target. For machining of mechanical parts, the standard is to specify the points, lines and surfaces on which other points, lines and surfaces on the parts are based. In the design scheme and production process of equipment parts, the selection of points, lines and surfaces according to different provisions is one of the key factors that directly affect the machining performance of parts, the specifications between surfaces and the precision of parts. According to different functions and use places, standards can be divided into design scheme standards and processing technology standards.
