High Speed Spindle - Standard Spindle Differences
The High Speed Spindle 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).
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.
