Remote Service

KERN teleservice – worldwide fault management

In order to minimize waiting times, our trained service technicians worldwide can directly access your KERN machine via a secure internet connection. Through this process, components and control systems can be checked, a diagnosis made and the fault rectified. But it is always your decision when to give our technicians access to your machine. KERN teleservice functionality can be retro-fitted to many existing KERN machining centers.



Our inventory of replacement parts is comprehensive, even for older KERN machines.

We offer a special KERN service for high speed milling spindles. We hold a permanent stock of refurbished, quality checked replacement spindles for all KERN CNC machining centers. In the event of spindle damage you will immediately receive a replacement — but you only pay for the refurbishing costs of your returned defective spindle.


The regular maintenance of your KERN machine guarantees longevity, reliable operation and high value retention. In addition, maintenance prevents more expensive repairs, protects you from longer downtime and reduces production downtime costs to a minimum.

Factory Overhaul

Do you need a factory overhaul for your KERN machine? No problem!
For a custom factory overhaul we proceed as follows:
– First, we assess your machine (at your site or at our factory in Eschenlohe, Germany)
– We then create a cost estimate
– After placing your order, your machine is thoroughly checked at our factory and disassembled as required.
– Worn components are cleaned, overhauled or replaced
– On request, we can also repaint your machine
– We then perform a KGM calibration
– A final check completes the factory overhaul

After the factory overhaul, your machine will once again achieve the required level of KERN precision for the respective machine type. All replaced components have a six-month warranty.

Used Machines

When our machines “return home” to Eschenlohe after a trade-in, they undergo a complete factory overhaul and are then offered for sale as used machines. The procedure for a complete factory overhaul is basically as follows:

– The machine is completely disassembled and cleaned
– Worn components are overhauled or replaced
– After assembly, the machine undergoes our entire calibration and quality assurance process – exactly like a new machine
– We provide a six-month warranty with all used machines
