Big Kaiser, a specialist in precision tooling systems and solutions for the metalworking industry, is introducing its Hydraulic Chuck Ultra Precision. The new chuck, which is suitable for machine shops that require the lowest possible runout in high-precision milling, is available in the UK from Industrial Tooling Corporation (ITC).

With Big Kaiser’s hydraulic clamping system for high levels of concentricity, the company guarantees runout of less than 1 µm at 4xD. This ultra-low runout does not drift, even after intensive use, whereas some shrink-fit holders become less accurate after each clamping, reports ITC.

Clamping with the new hydraulic chuck is easy and safe, requiring only an Allen key. This design makes it straightforward and quick to change tools in the machine. With no hot-clamping machines required, users can extend the life of the tool holder indefinitely, reducing costs and minimising the environmental impact of holder replacement in comparison with 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 our decades of experience and know-how, the new ultra-precision chuck delivers the excellent accuracy that our customers demand,” says Giampaolo Roccatello, chief sales andmarketing 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.”
