This diagram should help you ...

• To select the correct brush or disk diameter,
• To work at the correct rotation speed and
• To run the most economical peripheral speed.

Finding the right product is not easy. The following summary of the general standard cut speeds will help you with this:

Grinding		Polishing
Metals – general	30 to 40 m/sec	Steel	30 to 35 m/sec
Stainless steel	20 to 30 m/sec	Non-ferrous metals	30 to 50 m/sec
Hard metals	10 to 15 m/sec	Light metals	40 to 45 m/sec
Thermoplastics	8 to 15 m/sec	Thermoplastics	5 to 15 m/sec
Thermosetting plastics	10 to 25 m/sec	Thermosetting plastics	25 to 30 m/sec
Acrylic glass	3 to 8 m/sec	Polyester paints	15 to 30 m/sec

On request, we treat our disks and rings with a special impregnation. This changes the lifetime and aggressive effect so other surfaces effects can be achieved. Impregnation is mainly for sisal products although it is also possible with cloth polishing rings.
