Seco Tools introduces its new Power Milling Chucks, with levels of holding power and transmittable torque rivalling those of hydraulic and shrinkfit holder types for maximized milling performance. Power Milling Chucks deliver enhanced application flexibility and cost effectiveness while they allow shops to reduce tooling inventories.
The Power Milling Chuck delivers 5-micron runout accuracy at 3XD. Through direct clamping technology, one Seco chuck can hold cylindrical plain 20 mm, 32 mm, 0.75″ and 1.25″ and Weldon shank tools of 20 mm and 0.75″. With the use of reduction sleeves, a single chuck also can handle shank diameters in cylindrical plain, Weldon and Whistle Notch tools from 6 mm up to 25 mm, 0.25″ up to 1.00″. The chucks accommodate milling tools – for roughing and finishing operations – as well as drilling and tapping tools.
Seco Tools Power Milling Chucks offer shops innovative advantages over standard collet chucks. A nut and needle-bearing design produces superior clamping power with minimum tightening force/torque requirements, compared with the steel-to-steel contact on collet chucks.
Optional coolant-stop screws enable Power Milling Chucks to engage through-tool coolant. These Seco chucks require no additional expense for ancillary equipment such as heating or hydraulic units.
Seco Power Milling Chucks are available for HSK-A, Seco-Capto™, DIN, BT and BT taper-face, and ANSI and ANSI taper face spindle interfaces. Each chuck includes a sleeve extractor, stop screw (with DIN, BT and ANSI interfaces) and operating instructions.
