Chucks

Hoffmann Group USA announces the new centering vise called the GARANT Xtric. The vice is equipped with a new chuck jaw quick-change system, which enables easy, tool-free changeover. A click mechanism gives the vise an interchange accuracy in the micrometer range. Top jaws, which can be rotated by 180 degrees, allow for a large clamping range and high variability when fixing components. And clamping using multiple GARANT Xtrics is not a problem, the center can be adjusted precisely to achieve top precision.

As a recent addition to its EPPINGER PRECI-FLEX modular tooling system, EXSYS Tool Inc. offers a two-collet chuck that doubles the machining capability of one turning machine tool turret station. Designed for Mazak QUICK TURN and QTU series turning centers with optional high-speed drive motors, Y-axis functionality and standard BMT turrets, the double-collet chuck can deliver speeds up to 10,000 rpm with a 1:1 ratio and 20 N-m of torque and features 1,000 psi, or 70 bar, internal coolant.

Kitagawa NorthTech Inc. introduces its new DKF Series of low-profile collet chucks. The DKF low-profile collet chuck features a compact nose, which is required when additional tool clearance is needed in tight workpiece and machining environments.

Dillon full grip jaws, machined from 6061 extruded aluminum for increased strength, are now available up to 28-inches in diameter. Machining from bar stock eliminates the porosity inherent with large-diameter aluminum castings, providing a stronger and more reliable workholding product.

Shops that seek to maximize milling performance while they reduce tooling inventories will benefit from newly introduced Power Milling Chucks from Seco Tools. With holding power and transmittable torque that rival hydraulic and shrink-fit holders, Power Milling Chucks deliver high precision with 5-micron runout accuracy at 3 times diameter in addition to enhanced application flexibility and cost effectiveness.

INDEX has announced the launch of its new G420 turn/mill center. The machine features identical 3,500-rpm twin spindles with 315 mm (400 mm optional) chucks and a robust 5-axis milling spindle that provides up to 12,000 rpm with an HSK-T63 interface or 18,000 rpm with a Capto C6 interface.

Get into quick change for a fraction of the cost of a quick-change chuck. The System 3 Quick Change Base Jaws from Huron Machine Products bolt to your chuck like a standard top jaw.

Carmex Precision Tools Ltd. sees a significant increase in demand for specialized tooling used in unique applications. According to Jim White, national sales manager for Carmex USA, “The ability of design engineers in leading edge industries to envision complex high-performance parts, coupled with new materials including made-to-order alloys, composites, glass, and ceramics, has resulted in the need for cutting tools that can deliver greater productivity and improved finish.”
