Precise fast-change chucks for sliders

In 2018, Big Kaiser introduced hydraulic chucks for Swiss-type turning centres. Now, the company is expanding its programme to include inch-size Standard-Type chucks, as well as new F-Type and R-Type chucks that are all available in the UK from Industrial Tooling Corporation (ITC).

The new F-Type single-wrench system simplifies cutting-tool changes on the tool post, saving setting time for the machine operator. Notably, the easy-access rear clamping design is suitable for configurations where the hydraulic chucks fit on the front tool post of the sliding-head turning centre. Clamping from the opposite side of the cutting tool and the optimised overall length design improve ease of use. The F-Type is available in a clamping range from 3 to 10 mm, while through-coolant delivery is also possible.

Big Kaiser’s new R-Type designation eliminates interference when working on both the upper and lower tool-post positions. This ability is a credit to the novel block design and screw tightening at an offset position on the tool side. The R-Type is available in a clamping range from 3 to 10 mm, and it is possible to use its oil holes for coolant delivery when mounted on the upper section of a sliding-head turning centre.

The Standard Type hydraulic chucks with tool-side clamping now come in inch sizes with the clamping range of 1/8”, 3/16” and 1/4” diameter.

To minimise machine downtime and provide operator safety, the new hydraulic chucks use a simple hex wrench that requires only two to three turns for both clamping and unclamping. Tightening is complete when the clamping screw hits the bottom, so controlling the tightening torque is not required.
