IMPROVE PRODUCTIVIY and TOOL LIFE
In drilling stainless-steel valve connector components, the existing tool provided poor chip evacuation, making it difficult to improve cutting conditions and tool life.
By applying a DMM head designed for stainless-steel machining, improvements in both tooling performance and machining efficiency were achieved.
