A basic tenet of metalcutting is shorter tools are more rigid than longer tools and generally deliver better cutting results. Closer proximity of a cutting edge to a machining center spindle or turning center turret translates into higher feeds and speeds with better surface finish and less chatter.
Productivity is up by 15 percent, tool life is up 20 percent and part cost is down 20 percent for face milling, drilling and boring operations at Engel Machinery Inc., York, Pennsylvania.
Fast CNC processing and high-pressure coolant contribute to removing metal at dramatic rates. But what should a shop know about cutting tools in high speed machining?
