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

EP-ONE WAY Contact Wheels
All contact wheels with aluminium core can also be supplied with a synthetic core. Main advantage of the synthetic core is,
the cost savings compared to that of an aluminium core. This makes it particularly suitable, if an aluminium core will not be
re-used due to high shipment costs to the re-covering company. Also, due to the one way system, tedious collection and
administration of old cores can be avoided. These special contact wheels are only available in standard sizes.
Please ask for your specific requirements.

– EP-Type A77/K
– EP-Type A8/K
– EP-Type A11/K
