Universal drag finishing machines

Visit our website at to find out more. We offer a wide range of drag finishing services using professional machinery.

Our drag finishing machines are often used in tool manufacturing for rounding cutting edges and polishing flutes on hard metal tools. They are also used to polish and smoothen shaping dies.

The pharmaceuticals sector uses drag finishing machines for polishing the pressing surfaces of tabletting punches. They are also used in motor racing for smoothing and polishing gears, valves and rocker arms, as well as in the watch industry for grinding and high-gloss polishing of gold, ceramic and stainless steel watch cases.

In medical engineering, drag finishing machines are used for grinding and high-gloss polishing of knee implants, while the metal industry uses them to smooth high-speed spindles, for example.

For us at OTEC, making sure our customers are happy is our biggest priority. Rest assured that we spare no effort when it comes to your workpieces. Drag finishing is ideal for sensitive and high-quality workpieces that must be smoothed or polished without contact.

In drag finishing, a rotating carousel with up to twelve rotating spindles immerses the workpieces into the medium.

The rotation of the carousel and spindles ensures that the workpieces are processed evenly. It is also possible to adjust the speed and immersion depth of the rotation, meaning that these machines can remove up to 40 times more material compared to conventional mass finishing.

We combine outstanding quality with full service. Whatever components or workpieces you need processing, we are the right partner for you. We offer unbeatable value for money, combining high quality with reasonable prices.

OTEC is the market leader for mass and drag finishing for implants, tools and jewellery, as well as stamped, turned and milled parts made from a range of materials. We offer a wide range of versatile and custom solutions.
