Chucks

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.

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.”

BIG KAISER announces the MEGA Micro Coolant Nut, a developed solution to provide precise coolant supply to micro cutting tools applications at high speeds.

In recent years, machine tool OEMs have completely transformed CNC turning centers through the application of several advanced technologies. Whether it's ultradense synthetic machine beds, faster rapid traverse and acceleration rates, integrated spindle motor spindles or powerful multi-tasking capabilities, nearly every feature of these machines has changed. There’s just one major exception. More often than not, OEM machine builders equip these modern high-performance turning machines with outdated chuck technology – as old as 60 years – and it’s quickly becoming the component that holds back a machine’s true potential.

The DeHoff G560-B1 is a custom machine designed to form the rifling grooves in gun barrels. The barrel is rotated by a 3-jaw chuck while a rifling button tool is pulled through the barrel by a hydraulic cylinder. The button tool deforms the rifling grooves into the internal bore of the barrel using a swaging process. All the rifling grooves are cold-formed in a single pass.

Kennametal’s latest weapon in the war on chatter is one that will have machinists everywhere saying, “I need that.” The new boring system boasts the most effective antichatter mechanism ever developed by Kennametal, and also offers an extensive range of indexable heads and shank sizes.

BIG KAISER is expanding its range of BIG Capto toolholders with the addition of a new size, C4, which is becoming increasingly popular as a quick-change system for turret tooling on lathes.
