The KERN idea: holistic spindle service for sustainable success

Cost savings by maximizing spindle power

Our goal for each customer: cost savings by maximizing spindle performance. We succeed if the spindle is optimally adapted to your individual operating condition in the machine. Therefore, repair measures focusing on the spindle alone often represent only a part of the big picture.

In order to generate long-term cost savings, it is often worthwhile, in addition to technically repairing and optimizing the machine spindle, to analyze the spindle “environment” in the machine more precisely in order to detect decisive reasons for failure and to avoid them in future. All our services are based on this idea.

For a smooth symbiosis between spindle and machine

KERN has established itself as a holistic expert for spindle repairs and spindle servicing of all makes as well as for fixing possible reasons for failure in the spindle environment of the machine. In cooperation with our customers – from medium-sized companies to large corporations – we develop holistic solutions with regard to the spindle-machine environment and create a smooth symbiosis between spindle and machine.

With our comprehensive and closely interlocked services, you will benefit from a worthwhile, long-term alternative to machine manufacturers and costly replacement spindles.


Spindle repair

Holistic repair, optimization and modification of spindles.
Services that go beyond mere repair: we advise you individually, service your grinding, turning or milling spindle and ensure that future failures are avoided. Our goal: to make your motor or belt spindle more efficient than if it were new.

Spindle consulting

Telephone expert advice or on-site analysis regarding your machine.
The spindle environment always in view: our consulting concept is based on close customer contact: only if we know you and your requirements exactly can we ensure that spindle and machine run optimally.

Spindle service

Preventive maintenance for maximum safety for your plants.
For long-term satisfaction: with preventive maintenance measures, we ensure that the interaction between spindle and machine works optimally in the long term and that failures are prevented.
“Whether for repair, consulting or service – quality is the top priority for all KERN services.”
– Marc Luippold, Workshop Manager
