PFERD 47912 - Unitized Mounted Point, Cylindrical Shape, 2" x 1, W242, 6AF (MH), 1/4" Shank
Multiple heavily compressed, non-woven layers, which are bonded together by a special grain/resin system. The aluminum oxide A version is ideal for general-purpose applications on steel and non-ferrous metals. The cylindrical shape is ideal for grinding bores, radii and contours.
Applications
- Cleaning
- Deburring
- Step-by-step fine grinding
- Roughening
- Structuring (matt finishing, brush matting and satin finishing)
- Surface work
- Work on weld seams
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.
Materials
| Aluminum | Copper | Steel materials with a hardness > 54 HRC |
| Brass | Fibre-reinforced thermosetting plastics (GRP, CRP) | Steels up to 370 HV (< 38 HRC) |
| Bronze | Hardened, heat-treated steels over 370 HV (38 HRC) | Thermoplastics |
| Cast steel | Nickel-based alloys (e.g. Inconell and Hastelloy) | Titanium |
| Cobalt-based alloys | Stainless steel (INOX) | Titanium alloys |
Recommendations
- For the best performance, use with a recommended peripheral speed of 2,000-4,000 SFPM. This provides an ideal compromise between stock removal rate, surface quality, thermal load on the workpiece and flap wheel/cross buff wear.
- Considerably reduce peripheral speed for work on materials with poor heat-conducting properties, e.g. titanium and stainless steel.
