BIG KAISER Hydraulic Chucks for Swiss lathes clamp and unclamp quickly using a hex wrench

BIG KAISER has expanded its Hydraulic Chucks for Swiss lathes to include inch-size Standard Type chucks, as well as new F Type and R Type chucks.

Standard Type Hydraulic Chucks with tool-side clamping are now available in inch sizes with the clamping range of ø1/8, 3/16, and 1/4 in.

The new F Type’s single wrench enables easy cutting tool changes on the tool post. The easy-access rear clamping design is ideal for front tool post. Clamping from the opposite side of the cutting tool and optimum-length design improves overall ease of use. It is available in a clamping range of ø3 to 10mm and coolant delivery is possible with an Rc(PT)1/8 in. screw.

The new R Type eliminates interference at both the upper or lower tool post positions with a unique block design and tightening at an offset position in the tool side. The R Type is available in a clamping range of ø3 to 10mm and its oil hole drills can be used for coolant delivery when mounted on the upper section.

The 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; controlling tightening torque is not needed. Once it is centred, the runout will not vary, even if a cutting tool is changed repeatedly.
