Big Kaiser debuts Super Slim hydraulic chuck for HSK-E25 machine spindles

May 7, 2017 – Big Kaiser says it is introducing the world’s smallest hydraulic chuck for HSK-E25 machine spindles, completing its range of Super Slim hydraulic chucks.

The Super Slim type of Hydraulic Chucks (HDC) are the “perfect” tool holders for precision finishing processes in confined areas with drills, reamers, ball mills, end mills, diamond reamers and grinding tools, says the company, adding that cutting tools with shank diameters of 3 or 4 mm can be clamped directly and are suited for high-speed micro machining applications. The Super Slim HDC require a single wrench for clamping and unclamping, a “much easier and safer solution” compared to heat shrink tool holders, explains the company. The external body diameter of the chuck nose is 14 mm and a gauge length of 40 mm. Each tool is balanced for speeds up to 60,000 rpm and runout accuracy of less than 3 microns at 5xd.
