Are you using straight shank mills assembled into side lock end mill holders? Time-saving solution : Traditional side lock end mill holders are inexpensive but can be costly in terms of efficiency. With a TIR of .001”, poor vibration damping and weak gripping power, this traditional toolholding method should be restricted to roughing operations at low speeds. There are, of course, faster alternatives. Integral shank indexable end mills perform 3x faster than straight shank mills assembled into side lock end mill holders; anytime you remove a joint, performance—and, in turn, efficiency—will improve.
Estimated time savings: 25-50% decrease in rough milling time
