Clamping Range: Ø.059"-.630" Multiplies existing machining center spindle speed 4, 5 or 6 times. Higher speed machining increases productivity with greater accuracy and superior finishes.
No Need to Rotate Machine Spindle
RBX Type For small diameter drills and end mills. Air supplied via stop block or through the machine spindle. All models have variable speed. Clamping Range: Ø.018"-.159" Super precise air-driven spindle technology enables high-speed micro machining on existing machining centers.
MAX 20,000 RPM
World’s Smallest Clamping Intervals
MEGA MICRO COLLET •Wide coverage for small shanks is available with clamping intervals of Ø.004" (Ø.1mm) •Compact in size; excellent clamping force for small precision applications
Minimal Thermal Displacement The air turbine drive prevents thermal expansion of the spindle, which is essential for die sinking and high accuracy micro machining.
High Precision Collet NEW BABY COLLET Clamping Range: Ø.010"-1.000" & Ø.5-25.4mm
The world’s highest precision collet was developed based on BIG’s long experience and know-how. Each collet is inspected twice to guarantee the maximum runout tolerance permitted.
