High Speed Spindle
An option with the engraving head is a high speed spindle. It can be identified by looking at the spindle
pulley (the driven pulley) on top of the spindle. The high speed spindle uses a much smaller diameter
pulley than the standard engraving spindle (0.75" diameter). The standard spindle uses a driven pulley
and drive pulley of the same diameter (1.375" diameter, for a 1:1 ratio) and therefore, turns the same
RPM as the router motor. The high speed spindle runs at a ratio of 1.833:1. When determining the RPM
of the high speed spindle, the user must multiply the speed shown in either the tool options in the Vision
9 software, or on the Pendant by 1.833. As an example, to achieve 27,500 RPM at the spindle, the
router motor must be set to 15,000 RPM (15,000 x 1.833 = 27,500).
Mounting and connections are the same as for the standard engraving head.
NOTE: The high speed spindle uses a shorter drive belt than the standard spindle. You can
identify the belt used for the high speed and standard speed spindles as per below.
