Does Kern produce turned parts?

Basically, we are not a supplier for turning operations, but we manufacture parts that would initially be assumed to be in the turning area, but which are in our area due to special requirements with regard to microtechnology and accuracy.

What are quality standards at KERN?

Before each start of an order, a part of each drawing dimension is checked and documented. (internal initial sampling) When all dimensions are within tolerance, the series is started. During series production, test plans regulate the measuring frequency, and SPC evaluations can be generated via our Zeiss PiWeb.

How does KERN certify?

According to ISO 9001 and 14001

Does KERN train?

Kern himself trains industrial mechanics and mechatronics technicians and exclusively employs skilled personnel on the processing machines.

How long does a delivery take?

This is very dependent on the scope of processing and can range from 3 weeks to 12 weeks, depending on the requirement.

How many pieces can be produced?

Kern produces series from 50 to 50,000 pieces, including the necessary prototypes. In the area of eroding, smaller quantities can also be offered.

How accurate is the machining of components?

Our machining spectrum ranges from micro parts smaller than 1mm up to component sizes of approx. 200x200x100mm.

What are the key data of micromachining?

Use of micro tools: drills from Ø 0,03, milling cutters Ø 0,05, taps M0,2
Spindle speeds of 50 000 1/min


OpenMind provides us with all features of programming, up to 5-axis simultaneous milling.

What exactly are the achievable tolerances?

In series production, we can maintain tolerances of (+ /-) 2µm measured on the component. In addition, our entire production is air-conditioned.

Technology transfer at machine purchase?

In the case of machine investment, we offer you the opportunity to take over the manufacturing processes of parts production.
