High-Performance VC Collet System

Operating at up to 40,000rpm, the high performance VC toolholder offers high-speed, high-accuracy, and ultra-smooth surface finishes – runout is within 0.00012".

The slim and smooth profile eliminates noise related to high-speed rotation, while it reduces the air current created by the hex nuts and slots on the periphery of most toolholders. Dampening of micro-harmonic vibrations is achieved with the use of a groove under the nut. A thicker wall at the base of the VC, and its short gage length, allow for greater rigidity and static stiffness. As an option, axial adjustment is easily achieved with an adjustment screw. High pressure coolant-thru is also available. The VC design features a TiN bearing nut that makes greater torque possible by reducing the friction associated with nut tightening.

The 8° collet design of the VC further contributes to rigidity and gripping torque. The extended straight portion of the collet pilots and maintains the concentric placement of the tool. Its flat shoulder design results in heightened perpendicular force transfer. The VC is balanced with the collet for operation up to 40,000rpm.

The VC does not require fixtures or couplings to install or remove collets from nuts. A GH handle wrench provides two-way lock and unlock for quick installation of tooling. The VC is available in 30-, 40-, and 50-tapers, as well as HSK and Nikken 3-Lock models.
