Due to the hydraulic clamping system, which ensures excellent concentricity, the runout is extremely low – guaranteed to be less than 1 micron in 4D. This ultra-low runout stays at this precise level, even after intensive use, whereas shrink holders from competitors become less accurate after each clamping.

Clamping with the new hydraulic chuck is easy and safe using only an Allen key (also known as a hex key), making it straightforward and quick to change tools in the machine. With no hot clamping machines, holder life is extended indefinitely, reducing costs and minimizing the environmental impact of holder replacement as compared to shrink-fit holders.

Part of BIG KAISER’s HDC (hydraulic chucks) series, the new chuck provides precise clamping in 3-, 5- and 6mm diameter.

“Based on BIG KAISER’s decades of experience and know-how, the new ultra-precision chuck delivers the excellent accuracy that our customers demand,” said Giampaolo Roccatello, Chief Sales & Marketing Officer for Europe at BIG KAISER. “Shrink-fit holders may cost slightly less up front, but when you factor in the time wasted and the cost of heating and cooling equipment, it’s clear that hydraulic chucks are a more economical option over their lifetime.”

The Hydraulic Chuck Ultra Precision is available now.
