POLINOX® Convolute Wheel, 8 x 1", fine Grit, EH (extra-hard)

Technical information

8 x 1", fine Grit, EH (extra-hard)

POLINOX® convolute wheels produce matte surface finishes. POLINOX® convolute wheels are made 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 service life and abrasive performance. This particular bond results in non-woven wheels with a very good surface finish, high stock removal rate and long service 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, as well as portable power tools like straight grinders. Dressing the wheels allows them to adapt to different workpiece geometries. Extra-hard version with excellent edge strength for demanding deburring work.

Special features

• Cost-effective due to high abrasive performance and durability.
• Produces very good surface quality.
• Can be profiled as desired, enabling optimal adjustment to the contour.

Applications

• Cleaning
• Deburring
• Step-by-step fine grinding
• Roughening
• Structuring (matt finishing, brush matting and satin finishing)
• Surface work

Materials that can be worked

• Stainless steel (INOX)
• Steel materials with a hardness > 54 HRC
• Steels up to 370 HV (< 38 HRC)
• Thermoplastics
• Titanium
• Titanium alloys
• Zinc
• Aluminum
• Brass
• Bronze
• Cast steel
• Cobalt-based alloys
• Copper
• Fibre-reinforced thermosetting plastics (GRP, CRP)
• Hardened, heat-treated steels over 370 HV (38 HRC)
• Nickel-based alloys (e.g. Inconell and Hastelloy)

Recommendations for use

• Considerably reduce peripheral speed for work on materials with poor heat-conducting properties, e.g. titanium and stainless steel.
• For the best performance, use with a recommended peripheral speed of 4,000 SFPM. This provides an ideal compromise between stock removal rate, surface quality, thermal load on the workpiece and tool wear.

Safety

• For safety reasons, the maximum permitted rotational speed indicated must never be exceeded.
• The spiral-wound construction requires that these wheels only be run in a single indicated direction. Failure to do so will lead to destruction of the wheel and increased risk of accidents.
