Processing is carried out in an open drum (the process container) with a base plate in the form of turntable or disc. The workpieces, together with a suitable polishing or grinding granulate, are set in motion by the rotation of the disc to create a toroidal stream inside the stationary drum. The contact between the workpieces and the medium generates a very intense finishing effect which is up to 20 times more efficient than can be achieved with systems such as conventional vibrators. Only we at OTEC have the relevant know-how to finish very fine workpieces (< 0.4 mm) using our zero-gap drum system. This makes these models especially suitable for the deburring, edge rounding and polishing of delicate and intrate workpieces.

The innovative combination of Electro Finishing Technology with established mass finishing technology from OTEC delivers high-gloss perfection for workpieces with complex geometries in diverse sectors. This enables maximum gloss even in the smallest of corners and surface polishing without micro-scratches for large parts as well. Reliable, precise and efficient, this technology sets new standards for surface quality and cost-effectiveness.

Disc finishing machines from OTEC rapidly smooth additive surfaces. Depending on their dimensions and volume, workpieces can be homogenised as bulk goods in a single post-processing step. Our machines reduce manual rework to the absolute minimum if not to zero, as well as cutting series production unit costs. Our ergonomic machine design enables simple, flexible handling for operators and straightforward integration into existing process chains. The OTEC CF-Series is the perfect solution for everything from small runs to volume production.
