Consequently an advancedmachinetool design can justify the higher cost of a more capable and complex spindle package in fact a fast and accuratemachinetool will demand a reliable highspeed spindle system this paper will give a brief overview of the major components required to comprise a high speedmillingspindle design
This improved performance ismadepossible by the optimization of allball millsystems parameters including the incorporation of a highperformance classifier improved control systems and grinding aids a closedloopball millclassifier circuit can be positioned on load cells for weighing the totalmillcontent of media and material
Millingfeed the feed milling machinefeed can be defined as the distance in inches per minute that the work moves into the cutter on themilling machineswe have here at lbcc the feed is independent of the spindle speed this is a goodarrangementand it permits faster feeds
