Description

POLINOX convolute wheels PNK produce matt surface finishes.

POLINOX convolute wheels PNK consist of spiral-shaped, non-woven abrasive which is wound around a core and foamed up. The foam supports the non-woven component and positively impacts its tool life and abrasive performance. This particular bond results in non-woven wheels with a very good surface finish, high stock removal rate and long tool life. These properties are particularly apparent when deburring, blending, finishing and polishing soft metals, alloyed and high-alloy steels, in addition to titanium alloys. The wheels can be used on stationary machines and bench grinders, in addition to portable tool drives such as straight grinders. By dressing the wheels, they can also be adapted to the geometry of special workpieces.

Medium-soft version with increased flexibility and tool life for coarse blending applications and for light deburring and polishing work. Well-suited for working on edges.

Advantages

High economic efficiency due to high abrasive performance and long tool life.
Produces very good surface quality.
Can be profiled as desired, enabling optimal adjustment to the contour.

Recommendations for use

Considerably reduce cutting speed for work on materials with poor heat-conducting properties, e.g. titanium and stainless steel.
For the best results, use at a recommended cutting speed of 20 m/s. This provides an ideal compromise between stock removal rate, surface quality, thermal load on the workpiece and tool wear.

Safety notes

For safety reasons, the maximum permitted rotational speed indicated must never be exceeded.
The wound construction of the tool requires that the indicated running direction is strictly observed. Non-compliance with the running direction will lead to destruction of the tool and carries an increased risk of accidents.
