Big Kaiser, a global specialist in premium high-precision tooling systems and solutions for metalworking industries has announced the arrival of its new Hydraulic Chuck Ultra Precision.

The new hydraulic chuck is ideal for all machine shops that require the lowest possible runout for high-precision milling. It is available in the UK from Industrial Tooling Corporation (ITC).

Big Kaiser’s hydraulic clamping system ensures excellent concentricity, with runout guaranteed to be less than 1µm at 4 x D. The company says this ultra-low runout remains precise even after intensive use, whereas some competitor shrink-fit holders become less accurate after each clamping.

Clamping with the new hydraulic chuck is easy and safe, requiring just an Allen key, making it straightforward and quick to change tools in the machine. With no hot clamping machines required, the life of the tool holder is extended indefinitely, reducing costs and minimising the environmental impact of holder replacement when compared to shrink-fit holders.

As part of Big Kaiser’s HDC (hydraulic chucks) series, the new chuck provides precise clamping in 3, 5 and 6mm diameters.

“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 and 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.”
