DRAG FINISHING UNITS DF SERIES PERFECT SURFACES WORLDWIDE

2 | THE DRAG FINISHING PROCESS OTEC: WE MAKE THE DIFFERENCE Polishing, deburring, rounding or smoothing: We build drag finishing systems to finish any surface quickly and affordably. From small series production to large-scale industrial manufacturing. DF knee joint Video about finishing knee joints The OTEC drag finishing process is predestined for the finishing of large or heavy workpieces which cannot be finished in bulk. The workpieces are clamped in rotating holders and dragged through the process media at high speed. The high contact pressure and relative velocity between the workpiece...

WE GET YOU TO THE FINISH WITH μ PRECISION OTEC-optimized surfaces ensure that workpieces fulfil the high requirements of our customers. The focus here is on the finish or properties of the surface. In series produc tion, reliably repetitive results and costeffectiveness deliver a real competitive edge. Residual burring and swarf from the manufacturing process on the edges and surfaces impair the quality of a workpiece. By choosing the right media and the right process, these blemishes can be removed to give trouble-free downstream finishing and better handling. Edges are generally rounded in...
