CHANGING SPINDLE SPEED:
This model 25-200 MAXI-LATHE VS + is equipped with an electronic variable speed controller allowing the user to
change the speed of the spindle (within the 3 different spindle speed ranges: 300-900, 600-1800 & 1200-3600 rpm) by
simply turning the speed control dial. The digital spindle speed readout will indicate the operating spindle speed.
Note: Turning speeds vary depending on the size and diameter of the workpiece as well as which stage you
are at in the overall turning process. When turning a smaller diameter workpiece, a higher spindle speed is
recommended. Proper spindle speed selection comes with practice and experience and when in doubt
always start at a slower speed increasing when you are sure that it is safe to do so.
