BIG Kaiser’s Mega ER Grip, a premium ER collet chuck system featuring runout accuracy of 0.00012” (3 microns) at 5×D.

The system was designed to outperform all other ER systems in the four most crucial areas of toolholder performance: clamping force, concentricity, rigidity and balance at high spindle speeds. A major design improvement increases the contact length of the chuck body internal taper, reducing the undesired overhang of the collet for significant performance enhancements.

Customers will also see improvements in machining quality and shorter production times because of reduced cutting vibrations, the company says.

All components of the Mega ER Grip system are manufactured with BIG Daishowa’s high precision production technology: a high-rigidity body, a precision notch-free nut and an AA-grade ERC collet. ERC collets are in accordance with DIN6499 and ISO15488 standards and feature a clamping range of 0.075” to 0.787” diameter. With the Mega ER Perfect Seal, coolant can be delivered through the tool or to the cutter periphery. Tapped holes around the body periphery promote precision balancing, and the system is only available with dual-contact Big Plus (CAT), HSK and CAPTO interfaces to ensure maximum rigidity.
