Big Kaiser Hydraulic Chucks Change Tools Quickly
PMTS 2019: Big Kaiser’s hydraulic chucks use a single wrench, enabling quick change of cutting tools on a gang slide.
Big Kaiser’s hydraulic chucks use a single wrench, enabling quick change of cutting tools on a gang slide. To minimize machine downtime and provide operator safety, the chucks use a hex wrench that is said to require only two or three turns for both clamping and unclamping. To maintain repeatability, once a hydro-chuck is centered, the runout will not vary, even if a cutting tool is changed repeatedly. Runout of fewer than three microns at 4x diameter can be achieved, according to the company.
High-precision cutting with hydraulic chucks is said to be achieved on the automatic lathe with a clamping diameter ranging from 4 mm to 8 mm. According to the company, they are long-lasting, maintenance free and the rigidity is greatly improved by the short projection length and dual pressure points. Additionally, the chucks have a standard pipe thread for coolant through connection and are available for most machines with ¾" (22 mm) straight shank.
