We have all the key technologies in-house to produce components with an accuracy of 2 µm. We combine high-precision milling, micro-milling and -drilling, wire and die-sinking EDM as well as lapping and surface grinding. For complex machining processes, we design individual automation equipment for series production. We reliably cover surface coatings and other manufacturing processes through our pool of suppliers.

High-precision measurement is a prerequisite for the production of micro and ultra-precision parts. The measuring and testing equipment used in Kern contract manufacturing is correspondingly extensive and of high quality. They comprise more than 1,500 different measuring and testing devices, which are regularly calibrated according to ISO 9001 requirements. The Kern measuring laboratory is kept at a constant temperature of ± 0.5 K and is equipped with five high-end measuring machines.
In 1981 the shop needed a particularly precise machine. Since it was not available on the market, our engineers developed the first own Kern machine for different applications. Today, Kern's CNC machining centers are known around the globe for their reliable high-precision manufacturing.
This is a great advantage for our customers: In our Kern shop, the Kern machines ensure the best results for the most demanding applications 24 / 7. Also, experience and results from our shop go right back into the development of our Kern CNC precision machines.
In our Kern shop, we are specialized in high-precision machining of a wide variety of materials, including exotic ones. In addition to common materials such as brass, aluminum and stainless steel, these include in particular:
Copper alloys such as nickel silver and tungsten copper
Nickel-based alloys such as Inconel, Hastelloy and Nitinol
Special alloys such as Kovar, Invar and ferrotitanite
Hardened tool steels and hard metals
Technical plastics like Vespel
Carbides such as molybdenum and tungsten
Millable ceramics such as Macor and boron nitrides
Hard ceramics such as zirconium oxide and aluminium oxide
Precious metals such as gold and platinum
Our air-conditioned facility is home to the best machine tools available for ultra-precision machining. In addition to the Kern machines, machines from leading manufacturers such as Agie, Hermle and ZEISS complete our manufacturing spectrum or ensure μ-accurate measurement and quality control.
