Hardware industry-pure copper valve

Article Source:Haizhou | Author: | Time:2020-06-24

Processed products: hardware industry-pure copper valve


Problems and difficulties:

1. The production and processing are fast-paced, and the tool adopts the fast-in and fast-out processing method.


2. After processing, some products have obvious lines on the surface, which need to be reworked and reprocessed, and occupy a large proportion.


3. Tool wear is too fast, the number of tool changes is too frequent, and processing efficiency is low.


Advantage:

Designed to quickly adjust the knife block, designed to be wavy on the bottom of the installation, to increase the axial support force. Single-blade PCD+single-blade tungsten steel combined processing can perfectly ensure that all products have a bright surface after processing, and the special PCD material can greatly improve the life.
