Stream Finishing Machines Offering Fully Automated Surface Finishing

Performance Superfinishing with Automatic Loading and Unloading

Exclusively available in the UK from Fintek, OTEC Präzisionsfinish stream finishing machines offer deburring, rounding and smoothing in a single, short processing cycle that does not compromise the dimensions or contours of the workpiece.

Workpieces, clamped in a holder are lowered into a rotating container of media. Path-controlled motion allows precise areas of a workpiece to be processed. Even difficult to reach regions such as small chip flutes can be targeted. Holders can be customised to meet any requirement.

SF machines achieve surface smoothness to Ra 0.01µm making them a true superfinishing system.

Fully automated loading systems are available to meet in-line production needs in automotive, aerospace and other precision industries. 

Pulse Finishing

OTEC’s patented pulse drive technology can be specified for SF units. Developed specifically for automotive and toolmaking customers, pulse finishing produces rapid relative motion between the media and workpiece by quickly changing the direction of rotation of the heads. High speed acceleration and deceleration increases the finishing forces exerted on the workpiece making it possible to deburr, round and smooth surfaces from Rpk 0.2µm to 0.1µm in under a minute.
