About Keller Feinwerktechnik GmbH
Who we are
Since 1985 we have been producing high-quality and demanding precision turned and milled parts for a wide variety of industrial applications on computer-controlled machines and assemble assemblies to customer orders. In the field of special machine construction and automation technology, we have been developing customer-specific solutions from a single source since 1982, from user-specific task definition to commissioning and service. In 1992/93 we moved into the new premises at the A23 exit Elmshorn. A qualified and motivated team, decades of experience and state-of-the-art operational equipment give us the certainty of meeting the requirements of our customers at all times, both now and in the future.
