The chasing operation requires a very skilled lathe operator and the machine should be extremely sturdy as, at any given time, several teeth of a chasing tool are cutting into the roller, resulting in a heavy load being placed on the various components (the tool holder, saddle, cross slide, etc.).
For resharpening one pair of 304 grade stainless steel CTC rollers, the chasing tool and the milling cutter require resharpening twice.
