With the HSK-EZ15, Bid Daishowa introduces a new collet chuck for micromachining. The collet chuck was developed in accordance with the HSK-EZ15 standard. This new interface replaces the previous ATC-E15 standard and enables the miniaturisation of spindles to meet the requirements of the microtechnology market in terms of precision, performance and reliability.

The HSK-EZ15 type is available in three variants with outer diameters of 10 mm, 12 mm and 14 mm. Each variant is suitable for high-speed machining of workpieces and is suitable for milling cutters or drills with diameters from 0.45 mm to 6.05 mm. Big Daishowa guarantees a concentricity of less than 3 µm at the cutting edge — measured at 4 x D of the clamping diameter. These collet holders can be used at speeds of up to 80,000 rpm.

The slim body and specially developed nut ensure high rigidity and reduced susceptibility to interference during high-speed machining. The groove-free clamping nut prevents vibrations and noise and ensures excellent balancing and concentricity. This design reduces air noise and vibrations at high speeds and thus improves the machining process.

With the new HSK-EZ15 spindle interface, functions can be integrated into the machine spindle that were previously only possible with larger spindles.

“When finishing bores and fits, high cylindricity and surface quality are crucial for the end product. With the HSK-EZ15 collet chuck, we enable our customers to achieve the best possible results and thus increase their productivity. Big Daishowa was the first company to develop an industrial tool holder that made it possible to sell these machines in series,” says Christian David, Sales Manager at Big Daishowa. “By using a smaller spindle with a lower mass and smaller dimensions, energy consumption can be sustainably reduced.”
