BIG Kaiser launches world's smallest chuck for HSK-E25 machine spindlesClick image to enlarge

BIG Kaiser has introduced what it says is the world’s smallest hydraulic chuck for HSK-E25 machine spindles, completing its extensive range of BIG KAISER 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. Cutting tools with shank diameters of 3 or 4 mm can be clamped directly and are ideally suited for high speed micro machining applications in the automotive, aerospace, medical, die and electronics industries.

BIG Kaiser designed the Super Slim HDC to require only a single wrench for clamping and unclamping, a much easier and safer solution compared to heat shrink tool holders. These chucks can clamp ultra-small endmills and drills directly, without needing a reduction sleeve. The external body diameter of the chuck nose is a mere 0.551" (14mm), and a gauge length of 1.575 in. (40 mm) making it compact and precise.  Each tool is precision balanced for speeds up to 60,000rpm and runout accuracy of less than 3 microns (.00012 in.) at 5xd.

“Our HSK-E25 tool holder lineup now includes BIG Kaiser’s high precision, low runout, hydraulic chucks,” says Jack Burley, VP of sales and engineering at BIG Kaiser. “These ultra-precise hydraulic chucks, with their extremely slim design, are perfectly suited for high-precision finish milling work on ultra-high speed spindles on machines with small work envelopes.”

The Super Slim HDCs for HSK-E25 machine spindles are available from stock; they are also available for the HSK-E 32 and HSK-E 40 spindle types.
