BIG DAISHOWA Launches World’s Smallest Hydraulic Chuck for HSK-E25 Machine Spindles

Hoffman Estates, IL – BIG DAISHOWA announces the introduction of the world’s smallest hydraulic chuck for HSK-E25 machine spindles, thus completing its extensive 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. Cutting tools with shank diameters of 3 or 4mm can be clamped directly and are ideally suited for high speed micro machining applications in the automotive, aerospace, medical, die and electronics industries.

BIG DAISHOWA 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” (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”) at 5xd.

“Our HSK-E25 tool holder lineup now includes BIG DAISHOWA’s high precision, low runout, hydraulic chucks,” says Jack Burley, President/COO of BIG DAISHOWA — Americas. “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.
