Advantages of the collet chuck spindle

Collet chuck sits directly in the Hardinge spindle
Maximum rigidity and clamping force are transferred to the part
Maximum utilization of the speed
Minimal weight on the spindle
Minimal overhang from the spindle bearings, which ensures that the spindle accuracy is transferred directly to the workpiece
Optimum T.I.R.
Clamping force directly above the workpiece
Excellent tolerances and surface finishes
Utilization of the maximum machining capacity of the machine possible
Longer tool life
Fast retooling

Driven tools
Driven toolholders start at 8,000 rpm and are optionally available with a 2:1 or 4:1 ratio up to 32,000 rpm when high speeds are required. Hardinge’s BMT driven toolholders offer excellent concentricity within 3 μ, making them one of the best tooling systems in the industry.
