Over many years, OTEC Präzisionsfinish GmbH has developed special process parameters for drag grinding, streamfinishing and disk centrifugal processes to enable fast and economical surface processing in consistently high quality. Successfully used by well-known customers worldwide, workpieces with different shapes and weights are precisely deburred, ground, smoothed or polished in a short time.

Whether prostheses, implants or medical equipment, OTEC provides you with process reliability and individually applicable know-how. OTEC offers its machines in various sizes, from benchtop machines for cost-effective small-batch production to large-scale industrial production - as needed.

This makes OTEC machines ideal for numerous medical and dental applications, such as surgical implants (bone plates, bone screws and joint implants), dental implants, teeth, dental tools and orthodontic appliances, but also for earmolds and stents in vascular surgery.

In addition to the machines, OTEC also supplies the right polishing and grinding media for optimum results.


application areas

Surgical implants

For high-strength implant materials made from high-alloy stainless steels and alloys, but also from ceramics and plastics. Our machines produce perfect surfaces with the smallest roughness depths in a system-safe and economical way according to the requirements of modern surgery. Perfect, highly polished surfaces, not the smallest scratches and roughness depths of 0.1 μm with absolute process reliability, even with very complex free-form surfaces. This is what characterizes the OTEC process. Video Knee burrs deburr, smooth, polish

Dental medicine

For the different materials of dental medicine as well as very small workpieces from soft to hard. OTEC machines are perfectly matched to the requirements of dental medicine.


For precise contour grinding of extremely rough surfaces as well as for the production of very fine surfaces of plastics
