Lyndex-Nikken’s MMC Mini-Mini collet chuck is designed to provide accurate small-diameter cutting for manufacturers that need more clearance and flexibility in machining. The MMC Mini-Mini collet chuck features a slim and compact body for precision machining with small-diameter tools (up to 0.500"). This will enable high runout accuracy with optimal surface finish and part tolerance.

The MMC collet chuck is well suited for high-speed machining applications where clearance is needed, such as die mold, aerospace and medical parts. The MMC collet chuck is also an alternative to a shrink-fit system.

A draw-in collet clamping mechanism (no collet nut required) provides strong, high-precision gripping from the front nose that can access hard-to-reach areas. Because a collet system is used, tool changeover is faster and less expensive than a toolholding system that requires a machine in order to insert or extract the cutting tool. The collet system for the MMC also allows for a wider range of sizes, while a shrink-fit system requires a toolholder for each size of cutting tool.

The MMC collet chuck is said to be precision ground and pre-balanced to 30,000 rpm at G2.5 with runout accuracy of 3 µm at four times the diameter, providing accuracy and reliability during high-speed operations.

The MMC collet chuck is also available in a Taper Plus version, which combines taper accuracy with flange rigidity. Additionally, MMC collet chucks have through-coolant capabilities offered in a standard-style coolant collet or jet slotted-style collet.
