Mechanical spare parts processing refers to the parts or components of the installation mold; it can also refer to the mold parts or components that are re-installed on after damage. Precision molds usually consist of many parts, which can be divided into two categories: process parts and structural parts. Process parts can directly affect the quality of the forming product, and the decisive quality of the process parts are finished by finishing techniques in the current precision mold parts.
Mechanical spare parts processing progress is related to each other to the service life of precision mold and forming products, in the precision mold parts production and processing of finishing stage in addition to the choice of slow wire cutting, EDM forming and other technological practices, the other method is selected after the semi-finishing process, heat treatment based on grinding processing. Then in the precision mold parts production processing grinding processing stage need to control the deformation of the parts, internal stress, shape public service and scale accuracy and many other technical parameters.
In the complete production practice, the actual operation is more difficult, but in the hold Chuang 15 years of personal experience in precision processing can be summarized and analyzed to be able to learn the method: from the mold finishing progress adjustment precision mold parts production processing, we can specifically for different mold parts, different materials, different shapes and different technical requirements for adaptive production processing, supply selective program.
After the adjustment of the production and processing progress, to achieve a better production and processing role and economy is the key to most precision mold parts processing enterprises attach great importance to. The process progress of production and processing of precision mold parts is usually as follows: rough machining - semi-finishing machining - (quenching, tempering) - precision grinding - electric machining - clamping trimming - assembly production processing.
