Machine Adjustments; Adjusting The Table & Rack Height; Adjusting Headstock Height; Radial Head Position Adjustment - Promac JDT-2512V Mode D'emploi

When using a carbide (HM) tool,
approx. 5 times the speed is
permissible.
Generally speaking:
In proportion, the larger the rotation
diameter, the lower the possible speed.
For example:
Steel (C15) with 20mm diameter allows
a speed of
400 rpm with HSS tool
2000 rpm with HM tool
