Lyndex-Nikken, manufacturer and provider of high-performance machine tool accessories, offers the VC collet chuck that provides high performance for aggressive machining.
For manufacturers that are looking to minimize common challenges such as vibration, chatter, heat generation, workpiece stability, and tool wear - the VC collet chuck provides excellent runout accuracy, cutting rigidity, high precision finish, and high-speed rotation. The VC collet chuck is ideal for aggressive milling, high speed machining, thread milling, and ultra-precision reaming applications.
A key design advantage of the VC collet chuck is a TiN bearing nut that reduces friction and improves runout accuracy of 3 microns at 4 times the diameter of the cutting tool. The TiN bearing nut improves surface finish and ultimately increases cutting tool life.
Additionally, the 8° internal taper collet and ground ion nitrided thread further improves the accuracy of the tool. With the extended collet and collet compression force being perpendicular to the centerline of the collet bore, this maximizes the runout accuracy and is another source of gripping strength. Other features include a thick wall design of the VC body providing cutting rigidity and improved dampening. Further, the symmetrical external nut design, without notches, allows for ultra-high-speed rotation of up to G2.5 at 40,000rpm.
Since a collet system is used, tool changeover is faster and less expensive than a toolholding system that requires a machine to insert or extract the cutting tool. The VC collet allows for a wider range of sizes from 0.079” to 0.5”, while with other toolholder solutions that require external equipment you need a holder for each size of cutting tool. The collet system enables fast and easy tool changes, reducing downtime and increasing productivity in CNC machining.
The VC collet chuck is also available in Taper Plus which combines taper accuracy with flange rigidity. Additionally, the VC has coolant thru capabilities offered in a coolant-thru disc, jet coolant splash, or slotted disc for different applications.
