Dec 08, 2016· Roundness depends on angles. However, with a wheel width of 6" ( mm) or 8" ( mm), that same angle may generate too much pressure toward the grinding wheel and cause chatter. Changing the angle to 20º or 25º will reduce the pressure and eliminate the chatter on the part.
Or we could do that part on a multiaxis machine that has a rotary Baxis and twin spindles for two Caxes, plus X, Y and Z. There's also a lower turret that gives you a second X and Z. So it gives you more axes, but the part itself is the same geometry," Anderson explained. So how many axes do you need?
