POLINOX PNK compact grinding wheels produce matte surfaces. POLINOX PNK compact grinding wheels are spiral-wound and foamed abrasive fleece around a Kern. The foam supports the fleece and influences its service life and grinding characteristics. This special bond produces non-woven wheels with an excellent surface finish, high ablation power and a long service life. These properties are particularly evident in the deburring, adjustment, finishing and polishing of soft metals, alloyed and high-alloy steels as well as titanium alloys.;The wheels can be used on stationary machines and grinding blocks, as well as with portable tool drives such as straight grinders. The wheels can also be adapted to the geometry of a special workpiece by means of dressing. Soft design with excellent grinding performance on contours. Very good for leveling surfaces.
Technical data
- Max. RPM 5100 RPM
- RPM, opt.: 2500 RPM
- Design: W (soft)
- Metric width: 50 mm
- Ø hole: 25.4 mm
- Abrasives: Corundum A
- ø Outer metric: 150 mm
- Grain size: Coarse
Benefits:
- High economy due to high grinding performance and service life.
- Achieving very good surface qualities.
- Optimal contour adjustment, since freely profiled.
Application recommendations:
- When machining poorly heat-conducting materials, e.g. titanium and stainless steel, reduce the cutting speed significantly.
- For best performance at a recommended cutting speed of 20 m/s. An ideal compromise is achieved between removal power, surface quality, thermal load of the workpiece and tool wear.

Processing tasks:
- Clean
- Deburr
- Step-by-step fine grinding
- Roughing
- Structuring (matting, line matting and satinating)
- Surface treatment
Drive types:
- Grinding block
- Flexible shaft drive
- Straight grinder
Safety Instructions:
- For safety reasons, the specified maximum permissible speed must never be exceeded.
- The wound structure of the tool requires that the marked direction of rotation is strictly adhered to. Non-observance of the direction of rotation leads to destruction of the tool and carries an increased risk of accident.
HORSE GONOMICS:
- PFERDERGONOMICS recommends POLINOX PNK compact grinding wheels to reduce the development of vibrations, noise and dust during use and to improve the working comfort.
