Air Power Spindle

Air Driven Spindle Speeders


Air Power Spindle is an air driven tool with variable spindle speeds up to 120,000 RPM that can be used on existing machining centers to provide dramatic enhancements to surface finish quality, to extend tool life, and to reduce wear on OEM spindles. Used as an additional spindle on a normal machining center, Air Power Spindle eliminates the need for an expensive, high-speed machine.

Plotted Position of a Test Bar at the Maximum Spindle Speed


Most problems associated with micro-machining are caused by poor dynamic runout of a machine spindle. Air Power Spindle delivers exceptional dynamic runout accuracy of less than .00012" (.003mm) at 4xø, even at 80,000 RPM!

Minimal Thermal Displacement in Z-axis


Shown to the right is the axial displacement compared to operating time. The air turbine drive prevents thermal expansion of the spindle, which is essential for high accuracy micro-machining.
