Hi All,
Lucky me!!, got some jobs with lots of 1mm dia hole up to 8mm deep. These range from about 200 hundred, up to 2000 holes per part. Have already tried some hole drilling and destroyed a spindle. (top bearing set getting too hot). I've been reccomended to fit spindle chillers, the spindle cartridge already has all the appropiate attachments etc, just need the chiller unit and plumb in.
Would a better alternative be to use a speed increaser, or air spindle?
Currently using a HSS Worm Drill at 8000rpm, F160 mm/min which performs really well. Max RPM of machine is 10000 RPM.
All your help appreciated
Matt
