Technology Newsletters

Our Technology Newsletters present you with the latest information on key topics and solutions to challenging problems from the world of surface engineering. Always brief and to the point and based on practical experience in matters of deburring, grinding, smoothing and polishing.

January 2012: Precise, even and fast finishing of taps and carbide drills in the SF machine

Obtaining an even finish when deburring taps and rounding cutting edges remains a major challenge, since protrusions such as the tooth crests of thread-cutting taps and the dead centers of twist drills, are considerably more rounded than the more deeply recessed areas. OTEC's process development department has carried out extensive tests using the new SF machines.
