Big Kaiser Releases ER Collet Chuck System
Big Kaiser has recently introduced the Mega ER Grip, a new premium ER collet chuck system featuring a runout accuracy of .00012" (three microns) at 5xD. The Mega ER Grip was designed to outperform all other ER systems in the four most crucial areas of tool holder performance: clamping force, concentricity, rigidity and balance at high spindle speeds. These factors, combined with the system's reliable and stable runout accuracy, amount to significant long-term savings. A major design improvement increases the contact length of the internal taper of the chuck body, reducing the undesired overhang of the collet for significant performance enhancements. "Our tests have shown that Mega ER Grip performs exceedingly well in these four areas," says Jack Burley, Big Kaiser vice president of sales and engineering. "The result is cost and down-time reduction thanks to longer tool life. Customers will also see improvements in machining quality and shorter production times because of reduced cutting vibrations."
