High Speed Machining has brought major benefits to manufacturers and will continue to do so. However, with so much talk about high spindle speeds it is tempting to retrofit for as high a shaft speed as possible, but there are more things to to be considered in selecting the right spindle.
Shaft Speed in Metres Per Second
(shaft diameter(mm)/19108) X r.p.m.
Shaft Speed in Feet Per Minute
(shaft diameter(in.)/3.82) X r.p.m.
