UBURR · CNC Application Case Study

Front & Rear Deburring of 17-4 PH Arthroscopy Drills.

Remove front and rear burrs from arthroscopy scissor joint bores automatically. Two UBURR™ tool-holder sets deburred Ø2.5 and Ø3.0 mm pilot holes in 17-4 PH stainless steel at 2,000 RPM, leaving 0.2×45° chamfers and saving the customer roughly 20 hours of manual work per month.

Stainless steel arthroscopy scissors, the reusable instrument whose joint bores were deburred with NOGA UBURR — Arthroscopy scissors: the finished instrument.

Pilot holes: Ø2.5 / 3.0 mm
Spindle speed: 2,000 RPM
Chamfer: 0.2×45°
Manual work saved: ~20 h/month

01 / The application

Precision bores in a reusable instrument.

The task

Remove burrs from the front and rear of machined drill holes for arthroscopy scissors.

The arthroscopy scissor joint is a reusable system that combines quality, durability and precise tactility in each instrument, providing an optimal solution for every angle.
