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.

This new development of the company OTEC grinds and polishes work pieces especially well in areas, where conventional techniques like e.g. robots fail. Through the tremendous speeds of the grinding or polishing medium (up to 16 m/s), this machine is particularly suitable for processing of corners, recesses, grooves, etc..

Bone plates of various sizes were with finished using a variety of ceramic media and then separated in the Unisepa separating unit. Previously, separation had been carried out by hand in a time-consuming process. The key design specification for this Unisepa unit was a separation rate of 95% for bone plates.

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.
