SF PULSFINISH machine
The SF PULSFINISH with the newly developed pulse drive was specially developed for the requirements of the automotive sector and the modern toolmaking industry. The PULSE FINISHING process enables the extreme requirements of large-scale series production to be consistently met in terms of process reliability, speed and finishing quality. For example, it is possible to deburr, round and smooth surfaces from Rpk 0.2 μm to Rpk 0.1μm in less than a minute and in a single processing stage. This achieved without adversely affecting the contours of the workpiece.

Drag finishing units
In the drag finishing process, high-quality workpieces are clamped in so-called drag finishing machines and describe a planetary motion through an abrasive medium. For this process, OTEC has developed special techniques to fulfil a wide variety of customer requirements. The use of a dual drive system with two electric motors enables workpieces, including the cutting edges of carbide drills, to be rounded uniformly, giving a considerable increase in tool life. By positioning the holders at an angle, the quality of polishing on the face of the workpiece, e.g. in the case of forming tools, can be improved considerably.

Drag finishing machines from OTEC are available for both wet and dry processing.

The drag finishing process is especially suitable for applications in:
the toolmaking industry (e.g. for rounding cutting edges and polishing the chip flutes of carbide tools to a high shine)
forming tools (for smoothing and polishing the pressing and forming surfaces)
  • Easy changeover of workpieces
