Stainless steel, titanium or ceramics - high-precision finishing of all materials

Over a period of several years, OTEC Präzisionsfinish GmbH has developed special parameters for the drag finishing and disc finishing processes in order to ensure fast and cost-effective surfacce finishing and consistently high quality. Whether for finishing prosthetic items, implants or medical equipment, OTEC is on hand to ensure that you benefit from reliable results and expert customization.

KNee joints

A perfect surface extends the life of replacement joints. Especially when treating the complex surface geometry of a knee joint, it is important for the material to be removed evenly during grinding and polishing, in order to ensure a perfect fit. The contact surfaces of knee implants must be homogeneous, precise and very smooth. With drag finishing machines Ra values of 0.01 μm can be achieved.moreDrag finishing machines

Best results for bulk items processed in CF disc finishing machines from OTEC. In order to obtain a good fit, unrounded but bur-free edges are required as far as possible. A smooth, polished surface is conducive to easy insertion and removal. Furthermore, the smooth surface simplifies the process of disinfection immediately before use. OTEC has developed a way to fulfil all three requirements in a single process. By using a disc finishing machine it is possible to create a smooth, highly polished surface without any significant edge rounding. After this single-stage process the workpieces are light in colour, have a pristine finish and exhibit a much higher quality. In this process Ra values of 0.03 µm can be attained. In contrast to this, bone plates usually require a considerable degree of edge rounding and the surface should be as smooth and homogeneous as possible. Here, too, a disc finishing machine is used, albeit with different process parameters. This enables all traces of stamping and chip removal operations to be removed in a very short time and produces a smooth, high-quality surface.moreDisc finishing machines

Ear moulds

The manufacturing process of ear moulds creates a rough surface which does not provide the accurate fit and comfort required for insertion into the human ear. In order to maximize comfort, these items must have a very smooth surface. In disc finishing machines ear moulds can be ground and smoothed in a short time. The special design of the machine gives a very high-quality smooth surface finish in a process that is gentle on the material. That sensitive workpieces can be processed reliably without fear of damage.ECO Maxi

Tabletting tools

Polish and efficient finish of the pressing surfaces. A very smooth contact surface is essential in order to reduce friction and thereby resistance, which in many cases enables the press to be operated much more efficiently. Furthermore, this reduces the tendency of tablets to adhere to the tools, which in turn gives a smoother tableting process. The end result is a considerable cost saving for pharmaceutical companies. Tableting tools can be polished perfectly in a fully automatic process.DF Pharma SF Automation
