UBURR · CNC Application Case Study

Rear-Hole Deburring of 17-4 PH Medical Drills.

Automate rear-hole deburring on Swiss-type production. On a Star SR-20 JII, a UBURR™ UB2500 tool-holder with a UB2022 blade deburred the back of Ø2.73 mm pilot holes in 17-4 PH stainless steel in 5 seconds instead of 1 minute by hand, leaving 0.17×45° chamfers. Spend $79 a month on tooling, save $3,250 a month.
