Milling Chucks Target Narrow Nose Diameter Needs for Mold Machining

To counter the challenges of shrink-fit tooling—including upfront cost, and potential tool setup bottlenecks—and provide a cutting tool solution with narrow nose diameters, Techniks Tooling Group’s acquired tooling division, Parlec, offers the Micron Mold-Style (M-Style) Milling Chucks. Parlec milling chucks were created for mold machining and feature narrow nose diameters, down to 0.35", reportedly providing the clearance needed to machine difficult-to-reach areas and avoid other mold features or obstructions.

Setting up tools in M-Stye Milling Chucks requires only a hook wrench without the need to invest in expensive machines, thus eliminating setup bottlenecks. Its thrust-ring clamping system also positively stops against the flange of the toolholder, making it easy to know when the nut has been properly tightened. Further, according to the company, M-style chucks have about four times the clamping power of ER collet chucks and, since no heat is required for tool setup, potential safety concerns are eliminated.
