High-Accuracy Collet System

Lyndex-Nikken's VC Toolholder, operating at as high as 40,000 rpm, offers runout within 0. 00012" at 4 × D and finishes. Its design 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, the company says.

Lyndex-Nikken's VC Toolholder, operating at as high as 40,000 rpm, offers runout within 0.00012" at 4 × D and finishes. Its design 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, the company says. The dampening of micro-harmonic vibrations is achieved with the use of a groove under the nut. What's more, a thicker wall at the base of the toolholder and its short gauge length allow for greater rigidity and static stiffness, the company says. 

As an option, axial adjustment is achieved with an adjustment screw. High-pressure coolant-through is also available. The toolholder design features a TiN bearing nut that makes greater torque possible by reducing the friction associated with nut tightening.

The VC is available in 30-, 40- and 50-tapers as well as HSK and Nikken three-lock models.
