BIG KAISER’s new collet chuck guarantees precision with 1 micron runout

BIG KAISER announced the Mega New Baby Chuck 25N, the industry’s highest precision multi-purpose collet chuck system.

Designed for high-speed cutting, the Mega New Baby is available up to ø25mm clamping for drills, reamers and finishing end mills. It guarantees a 1 micron runout at the collet nose, with high runout precision of less than 0.003mm at 4 times diameter.

These precise and versatile collet chucks are offered in six different series sizes and are recognized for their accuracy in high-speed applications.

The Mega New Baby Chuck 25N has a clamping range from ø0.25mm to ø25mm. Its thrust ball bearings eliminate distortion of the collet during tightening and the patented design prevents ball bearings from moving at high speed.

Every chuck is 100% inspected twice to ensure accuracy. The materials, production and heat treatment are all carefully selected to ensure ultimate precision.

“The Mega New Baby Chuck 25N meets and exceeds the stringent demands placed on precision machining tasks,” says Giampaolo Roccatello, VP Sales at BIG KAISER. “It delivers the accuracy, robustness and versatility that make the difference on the shop floor.”

The Mega New Baby is available in BIG-PLUS® (SK/BT), HSK and BIG-Capto. A total of 353 different versions are available as standard, which means the ideal length and diameter of the holder can be selected, thereby always ensuring precision machining results.

A two-way coolant supply is provided either through the tool or via a jet system for tools without holes. Dust resistance is high.

The Mega New Baby Chuck 25N is available now.
