Fan Grinders Aluminium Oxide - 3mm Shank

PFERD provides mounted flap wheels / Fan Grinders with various
  • grit sizes,
  • abrasives and
  • dimensions.
PFERD mounted flap wheels are supplied with the standard shank length of 40 mm. The coated abrasive flaps are arranged radially around the tool axis in a fan-type configuration. Due to their flexibility, they adapt ideally to the contours of the workpiece. The abrasive grit is embedded in a resinoid bond on the strong, flexible backing cloth. PFERD mounted flap wheels are designated "Flap Wheels with Shaft" according to ISO 3919.

Advantages:
  • High flexibility
  • High stock removal due to the aggressive coated abrasive
  • Carrier material wears off uniformly and without residue on the workpiece surface, meaning that sharp abrasive grit is exposed at all times
  • Due to the flat cast core construction, the face of the mounted flap wheels can be used to work very close to edges and in corners
Application examples:
  • Fine grinding on radii in tool and mould construction
  • Machining of small and hard-to-reach areas in apparatus engineering and tank construction
  • Machining of fittings made out of nonferrous and light metals
  • Grinding of turbine blades in aircraft engine construction and repair
Recommendations for use:
  • Mounted flap wheels achieve their best performance at a recommended cutting speed of 15Ð20 m/s. This provides an ideal compromise between stock removal, surface quality, thermal load on the workpiece and tool wear.
  • Flexible shafts, electric and air-powered straight grinders can be used as tool drives
  • Use grinding oil that is suitable for the material in order to significantly increase the tool life and the abrasive performance of the tools. 
Factors influencing the work result:
  • Tool wear and thermal load: The reduction of the contact pressure and the peripheral speed, together with the addition of grinding oil, reduce tool wear and the thermal load on the workpiece.
  • Stock removal: An increase in stock removal should be attained by using a coarser grit size rather
  • than by increasing the contact pressure in order to prevent unnecessary tool wear and thermal load on the workpiece.
  • Surface roughness: The increase in cutting speed results in a slightly finer surface. By increasing the
  • contact pressure, the surface becomes slightly rougher. The softer the material to be worked, the rougher the surface (if the same grit size is used).
Safety notes:
  • For safety reasons, it is imperative to remain within the stated maximum permitted rotational
  • speed at all times
  • Safety is only guaranteed if:
  • The clamping depth is at least 15 mm
  • The specified maximum rotational speed for unsupported shank lengths is not exceeded
