Wurth Emery Wheel - K120 - 60x30X6m

672010631

Flap wheels achieve optimal performance at a recommended cutting speed of 15–20 m/s. An ideal compromise between the removal rate, surface quality and temperature load of the work piece and the service life of the flap wheel. The maximum permissible rotation speed (min-1) must never be exceeded for safety reasons. Flexible shafts, electric and pneumatic straight grinders can be used as tool drives.

Service life and heat development:

The low contact pressure and circumferential speed increase the service life of the flap wheel and minimise the temperate load on the work piece.

Material removal:

Increasing the removal rate should be achieved by switching to a rougher grain rather than increasing the contact pressure.

Surface quality:

High cutting speeds with low contact pressure produce fine roughness. Increasing the contact pressure with low cutting speed increases the depth of roughness. The softer the material to be machined, the greater the depth of roughness (when using the same grain size).
