Grinding affect the service life of mould research

摘要

In the process of modern mould manufacturing, grinding work still account for 25%～45% of the total manufacturing time mould. Mould manufacturing quality of the finished product is closely related to the precision of mould manufacturing, particularly with the mould cavity surface accuracy and surface roughness has a close relationship. In the manufacturing of mould to make grinding micro cracks and residual stress is reduced to a minimum, full attention, grinding process in order to improve the service life of mould. So research to improve grinding processing quality, improve the service life of the mold, to extend the time of service, has the positive significance.
