With 25 years of experience in mass finishing, OTEC is proud to provide custom processes for the unique requirements of the medical and pharmaceutical industries.Our well-established machine designs ensure rapid, cost-efficient surface processing in consistently high quality. Be it deburring, grinding, smoothing or polishing, OTEC delivers precision surface processing for workpieces of different sizes, weights and materials.

Homogeneous, smooth implant surfaces are essential for securing an accurate fit and extending lifespan. OTEC machines remove material evenly when grinding and polishing to ensure that implants can be inserted and disinfected easily.
To fit securely, the implant edges must be burr-free but not rounded. OTEC machines process complex surface geometries and hard-to-reach areas.

OTEC’s defined processes and suitable machine designs ensure our mass finishing machines can perform custom surface processing.

Medical instruments and tools must have sharp, burr-free edges to prevent bone-cell damage and to stop metal residues from entering wounds. At the same time, the surface must be smooth enough to ensure no tissue or blood adheres to it.

OTEC’s processing machines ensure consistent surface quality. They can carry out custom processing using methods matched specifically to the workpiece. They smooth surfaces and remove burrs without creating noticeably rounded edges.

Earmoulds are manufactured using additive or cutting processes which result in rough surfaces. During smoothing, the shape must be maintained in order to ensure an accurate and comfortable fit.
Surface processing with OTEC’s disc finishing machines enables mechanised pre-grinding, fine grinding and polishing. Manual pre- or post-processing is minimised, greatly reducing per-unit production costs.
