ITC Simplifies Advanced Micro-Machining

As an industry leader in premium high-precision tooling systems and solutions for the metalworking industries, Industrial Tooling Corporation (ITC) now announces the arrival of the new HSK-EZ15 MEGA Micro Chuck from BIG KAISER. This latest MEGA Micro Chuck collet version is specifically designed for applications using smaller workpieces such as jewellery, watches and micro-machining.

The HSK-EZ15 MEGA Micro Chuck is designed according to the HSK-EZ15 norm, a new interface used by the latest machine tools that replaces the previous ATC-E15 norm. HSK-EZ15 sets a new standard for compactness and precision by enabling the miniaturisation of spindles. It also meets the microtechnology market’s precision, performance, and reliability demands.

The new collet is available in three variations with 10, 12, and 14mm outer diameters. Each is perfectly suited for high-speed machining from 0.45mm to 6.05mm shaft size, maintaining a perfect runout of under 3µm at 4XD. These collet holders can be operated at speeds up to 80,000rpm. The BIG KAISER MEGA Micro Chuck from ITC is a compact, easy-to-use watchmaking and micro-machining solution that allows quick retooling for new parts. Its excellent guaranteed runout accuracy (under 3µm) meets the exacting standards of manufacturers in the electronics and small-part machining sectors. Additionally, it provides high positional accuracy, excellent repeatability and noiseless operation.

The BIG KAISER MEGA Micro Chuck is a collet chuck with a slim body and nut, designed with the highest rigidity for high-speed machining and reduced interference. It has a notch-free nut for high-speed applications, which prevents vibration and noise and offers superior balance and concentricity. This nut design eliminates whistling noise and coolant splattering and assures increased strength of the nut itself.

Giampaolo Roccatello, Chief Sales & Marketing Officer for Europe at BIG KAISER says: “The HSK-EZ15 is an innovative way of integrating functions into small spindles that were previously only possible with much larger spindles, such as presetting outside the machine to save time and increase productivity. BIG KAISER was the first company to believe in this project and to develop an industrial tool holder that would allow these machines to be sold in series. Using a smaller spindle with its reduced mass and physical dimensions enables a sustained reduction in energy consumption.”
