KAISER launches world’s first hydraulic chuck for tools down to 3mm diameter

ISER’s HDC sup slim, the world’s first hydraulic chuck for tools down to 3mm diameter

KAISER Precision Tooling, a leader in premium high-precision tooling systems and solutions for the automotive, mil/aero, energy, medical and watch-making industries, today announced its latest hydraulic chucks, HDC super slim. The new chucks can directly clamp ultra small mills and drills, without a reduction sleeve, with a diameter as low as 3 mm – the smallest size for any similar product, worldwide. The new chucks were developed for demanding finishing operations in confined areas. For clamping diameters of 3 mm the external diameter of the chuck nose is only 14 mm, and at a length of 90 mm the diameter is 25 mm – meaning that interference contours should no longer be a problem.

Thanks to their hydraulic clamping system with dual oil pressure points, the hydraulic chucks provide highly accurate, repeatable clamping with less than 0.0015 mm (1.5 microns) variance, and runout accuracy of less than 0.003 mm (3 microns) at four times diameter. This outstanding precision, in combination with rotation speeds up to 35 000rpm, helps to improve the surface finish of workpieces, as well as extending tool life. “Where only the highest precision is good enough, KAISER’s hydraulic chucks deliver the accuracy needed,” says Peter Elmer, CEO of KAISER.

KAISER’s chucks are easy to use, with only one wrench required for clamping and unclamping. The company’s hydraulic chuck range includes clamping diameters from 3 mm to 12 mm as well as various projection lengths to fit nearly any application in automotive, aerospace, medical, and die and mould.

The HDC super slim are available now for machine spindles HSK-E 32/40/63 and BBT 30/40/50.
