High Speed Ultra Precision Machining
The Ultra Precision EVO CNC Machining center from KERN Precision is equipped for 3-5 axis nano-precision machining of medium to large production lot sizes.
KERN Precision, Inc. (Webster, MA), the U.S. subsidiary of KERN Microtechnik GmbH (Eschenlohe, Germany), has announced it will present ultra– and nano-precision machine tool technology in Booth S-8980 at IMTS 2014 in Chicago by exhibiting the Ultra Precision EVO CNC Machining Center that is equipped for 3–5 axis machining of medium to large production lot sizes. KERN has driven innovation in the ultra– and nano-precision machine tool arena for more than 30 years.
The EVO machining center provides high productivity through fast acceleration, feed rates, and spindle speeds up to 50,000 rpm, while assuring the highest degree of precision on the part. The machining center’s polymer concrete mono-block frame absorbs forces and vibrations that occur during machining. Users can obtain the highest precision on a work piece due to the EVO’s construction and positioning accuracy of ±0.5 µm (0.00002 in). The EVO’s advanced machine technology also provides superb surface finish quality down to ≤ 0.1 µm Ra.

The ultra-precision system can be outfitted with comprehensive accessories and options such as a two-axis (B/C) high precision rotary table, a laser tool measuring system, touch probe and an automatic tool changer with 32, 63, or 95 positions. Optional spindles providing speeds up to 160,000 rpm are also available. Another potential add-on is an automatic work piece changer with 24 positions, alternatively with 36, 60, or more positions.
KERN Precision is a pioneer in ultra– and nano-precision machine tools. The renowned machine tool builder has a 30-year track record of delivering state-of-the-art machining centers to manufacturers all over the world. Its product line includes four multi-axis machining centers designed to provide positioning accuracies down to 0.3 µm and machine a variety of materials from aluminum to titanium.
