Satisfied Customers

“We were originally running parts with solid carbide tools and were having issues going through excessive amounts of tooling, along with long cycle times, since coolant wasn’t an option. […] Being our first step into PCD tooling, we didn’t know what to expect, but Lach Diamond did a fantastic job and helped us utilize the PCD tools to their full potential. The parts that used to take nearly 6 hours per cycle, have been reduced to only 35 minutes. Tool wear has greatly gone down as well, partially due to the PCD material, but also the tool pathing changes we could make due to the custom tooling they designed.”
