Expanded Hydraulic Chuck Offering for Swiss Lathes
May 1, 2022
BIG DAISHOWA has expanded its hydraulic chuck lineup for Swiss lathes to include inch-size Standard Type chucks, as well as F Type and R Type chucks.
Standard Type Hydraulic Chucks with tool-side clamping are available in inch sizes with the clamping range of o1/8", 3/16" and 1/4".
The F Type's single wrench enables easy cutting tool changes on the tool post. The easy-access rear clamping design is suited for front tool post. Clamping from the opposite side of the cutting tool and optimum-length design improves overall ease of use. The F Type is available in a clamping range of o3 mm to 10 mm, and coolant delivery is possible with an Rc(PT)1/8" screw.
The R Type eliminates interference at the upper or lower tool post positions with its block design and tightening at an offset position in the tool side. The R Type is available in a clamping range of o3 mm to 10 mm, and its oil hole drills can be used for coolant delivery when mounted on the upper section.
To minimize machine downtime and provide operator safety, these hydraulic chucks use a simple hex wrench that requires only two to three turns for clamping and unclamping. Tightening is complete when the clamping screw hits the bottom; controlling tightening torque is not needed. Once a hydraulic chuck is centered, the runout will not vary, even if a cutting tool is changed repeatedly. Runout of fewer than three microns at four times diameter can be achieved. Hydraulic chucks have a standard pipe thread for coolant-through connection and are available for most Citizen and Star machines with 3/4" or 22 mm straight shank.
