Tool Holding
Because Circular knives vary significantly as to diameter, bore, bevel angle, and general configuration, Knife holding flanges are quoted at request. Generally Clamping Flanges run from $200 to $800. Standard machine Shaft is 16mm.
Customers who are currently grinding circular knives on another machine, commonly find that they can use the clamping devices they already own.
