Ultra-precision hydraulic chuck with runout of less than 1µm

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

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

With Big Kaiser’s hydraulic clamping system that ensures excellent concentricity, the runout is guaranteed to be less than 1 micron at 4XD. This ultra-low runout retains this precise level even after intensive use, whereas competitors' shrink-fit holders become less accurate after each clamping.

Clamping with the new hydraulic chuck is easy and safe, requiring only an Allen key. This makes 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.”
