Sensitive workpieces can be efficiently deburred, rounded and polished using the drag finishing / drag grinding process. In the drag finishing process (or similar stream finishing or pulse finishing for Otec systems and Surf finishing for Rösler systems), each workpiece is individually clamped into the machine and subsequently dragged through grinding or polishing media. Depending on the desired processing result (from deburring to rounding to high gloss polishing in hand polishing quality) different grinding and polishing media can be used.
With drag finishing, a wide variety of components can be deburred, rounded and polished: We can process metal parts (aluminium, stainless steel, brass, HSS etc.), ceramic and titanium parts. Small parts and large parts up to 20kg. Turned and milled parts, sintered parts, additive manufactured components such as sintered parts and 3D printing components as well as cast parts can be machined.

Workpieces from different manufacturing processes
Drag finishing allows different processing results to be achieved:
Deburring / rounding: Burrs or stuck flakes can be removed completely. Sharp edges (e.g. of cutting edges) can be rounded up to a precisely defined radius.
Polishing / Smoothing: The roughness of components can be reduced, the surface can be polished to a high gloss.
Descaling / Cleaning: Oxide layers such as rust or annealing colours can be removed from the hardening process.
