Optimum result in belt grinding can only be achieved, when grinding belts and contact wheels are matched for the specific process.

Only the correct choice of contact wheel enables the belt to unfold all its potential, in respect of stock removal, flexibility and life time. For fine grinding with fine grit, soft contact wheels are used. For rough applications, a sturdy, medium hard to hard contact wheel is the correct choice.

Grooves on the contact wheel support the grit for better impact and stock removal. At the same time, they can help to clean the belt from grinding dust.

For very fine applications, smooth contact wheels with a flat surface are the right choice.
