Manufacturing Technologies
The special Kern ingredient: Combined processing
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 milling
The Kern contract manufacturing offers you μ-precise HSC machining (High Speed Cutting) in air-conditioned rooms for your machining task. With our modern machinery, we implement high-precision contours, free-form geometries and bores with form and position tolerances of up to ±1 μm with process reliability. This means that time-consuming adjustment can be dispensed with when assembling precision assemblies.
Micromilling and microdrilling
Many industries have a growing need for micro parts, be it analytics, medical technology or traditionally the watch industry. Kern contract manufacturing has more than three decades of experience in this field - since the development of the first micro milling machine - and is constantly developing further.
Wire and die-sinking EDM
EDM is a non-contact machining process for workpieces with combined requirements that go beyond milling, e.g. for special geometries or material hardnesses. In Kern contract manufacturing, we achieve the same precision for micro parts and micro structures with this technology as with high-precision milling.
Lapping, polishing and surface grinding
From the in-house production of high-precision Kern machine components, Kern Microtechnik has great know-how in the production of axis components, spindle beds and guide bearings for precision guide systems.
Laser marking and 3D laser processing
Laser marking is carried out using Trumpf equipment – the TruMark 3230 – enabling applications such as micro-marking and the creation of Data Matrix codes on almost any material. Even the highest requirements can be met thanks to cutting-edge technologies like our in-house developed Kern Femto E3 laser processing center. This system is designed for precise laser micro-machining of small workpieces and is capable of processing extremely hard materials such as tungsten carbide.
Laser processing
Kern is setting new standards in ultra-precise material processing with its Femto E3 laser technology. Thanks to ultrashort pulses, the process enables virtually heat-free machining, resulting in perfect contours even for complex geometries.
With our intelligent adaptive machining technology, we automatically compensate for peaks and valleys, achieving reproducible surface qualities – even under the most challenging initial conditions.
Parts cleaning
Cleanliness is a crucial factor for the functionality of modern high‑end components. That’s why KERN offers a well‑designed cleaning concept tailored to different industries and requirements.
Special Solutions
KERN is your partner for components where others have long given up. Our strength lies in combining technical expertise, deep process understanding, and the courage to explore new approaches.
Your benefits
Measuring down to the μ
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.
