OVERVIEW FINISHING MACHINES

Product catalog summary
Overview of Mass Finishing Processes

Disc Finishing: Utilizes a rotating base plate to move workpieces and granulate in a toroidal stream, offering efficiency up to 20 times greater than conventional vibrators. Best for small parts and large quantities.

Drag Finishing: Involves clamping and dragging workpieces through a drum with granulate, providing quick, high-quality results similar to manual polishing. Suitable for large, heavy workpieces.

Stream Finishing: Both the workpiece holder and process drum rotate, creating powerful forces for quick finishing. Ideal for deburring, polishing, and edge rounding.

Pulse Finishing: A variation of stream finishing with workpieces accelerated to over 2,000 rpm, suitable for large series production.

Company Background: OTEC Präzisionsfinish GmbH, established in 1996, specializes in innovative finishing machines tailored to industry needs.

Expert Advice and Services: OTEC offers free expert advice and sample finishing services, developing customized processing concepts.

Media and Applications: The choice of machine, media, and process is crucial for achieving perfect surfaces, with applications in polishing, edge rounding, and deburring.

Machine Types and Features: Details on machine series like SF, ECO, DF, and PULSFINISH®, highlighting applications in tool, gearbox, automotive, and turbine manufacturing.

Overview of Machine Series

SF Series: Features models like SF 3/105 with three workpiece holders for high precision in deburring and smoothing, suitable for automotive and toolmaking industries.

OVERVIEW FINISHING MACHINES-2

Disc finishing Mass finishing process, in which a rotating base plate sets workpieces and granulate in motion in a toroidal stream. The very intense finishing effect is up to 20 times more efficient than conventional vibrators. Especially suitable for: small parts, large quantities of bulk goods Drag finishing In the drag finishing process, the workpieces are clamped in holders and dragged at high speed in a circular motion through a process drum containing grinding or polishing granulate. This generates contact pressure between the workpiece and the media, which produces perfect results in a...
