When high spindle speeds were attempted in producing the slots, excessive runout and chatter caused match line problems while roughing with three cutting passes using a .75inch indexable insert end mill. By using the same end mill with a SinoT toolholder, the HMC's spindle speed could be increased from 8,000 to 14,000 revolutions per minute.
