The customer manufactures hydraulic rams and cylinders, and they are machining a body relief valve made from 4140 alloy steel. They are using a Nakamura TW-10 lathe running with synthetic thru-tool coolant.
Unsatisfied with their current production process, the customer needed a solution to increase tool life.
The ALVAN® Reamer helped the customer in multiple areas: it increased tool life, decreased cycle time, and improved the surface finish.
