CNC precision machining centres, developed and build in the Kern machine tool plant in Eschenlohe, deliver optimum results in the most demanding machining
assignments — around the clock, seven days a week. The Kern Contract Manufacturing division, which is based at our Murnau plant, draws on the know-how acquired by our Mechanical Engineering team in Eschenlohe. Conversely, our many years of experience gained in manufacturing practice continually flow into the ongoing improvement and optimisation of our machines. This close interlinking of Contract Manufacturing and Machine Engineering is what makes Kern Microtechnik unique!
In many applications the focus is not on achieving a sub-2 μm precision on the workpiece, but rather on the machine’s series stability, integration capability and cost-effectiveness. The sleek Kern Micro Pro is designed to perfectly meet these requirements.
With its proprietary X-Y cross table, Kern Evo delivers maximum precision in a small installation space. The design allows maximum smoothness and excellent surface finish (Ra < 1 μm) even at high speeds and acceleration values.
Short distances between components and drives ensure minimal angle errors, while ultra-high resolution direct measuring systems guarantee maximum repeat accuracy in a working space of 300 x 300mm. Kern Evo can be optionally equipped with a 4th and 5th axis without compromising the stability and high precision of the basic machine.
With high quality components in all peripheral modules and easy automation, Kern Evo is widely used for unmanned 3-shift production in all industries that demand maximum precision on the workpiece.
Advanced technologies for maximum precision
The incorporation of sophisticated, mature technologies makes Kern Evo perfect for highly stable serial production tasks:
Driven by hydrostatic bearings and guidings, Kern Pyramid Nano is one of the most precise CNC machining centers in the world. By focusing on reliability in serial operation, this machine achieves ultra-precision manufacturing of industrial workloads.
Advanced technology for μ-accurate serial production
At the heart of the machine are the axes, which are mounted on hydrostatic bearings and therefore promise virtually wear-free precision throughout its lifetime. This means the quality and precision of all axes remain constant over extremely long time-frames. In addition, the hydrostatic system enables high acceleration with excellent vibration damping, bringing productivity and precision into perfect harmony. In combination with Kern’s proprietary temperature management system, an optimally configured machine system is guaranteed at all times.
Kern’s sophisticated, mature product technologies give Kern Pyramid Nano significant advantages in precision manufacturing:
Direct hard milling with Kern – your benefits
The Micro and Evo machines by Kern fulfill all of these requirements superbly. They are continually being optimized through close collaboration with internationally renowned watch- and jewelry makers. Kern Microtechnik’s patented quick-release plates vastly improve efficiency by enabling both tool changes and the processing of different articles with a variety of machining methods — even during unmanned operation over long periods.
