Our expertise
in the field of machinery and food technology



Our range of services
for the machinery and food industry
The machinery and food technology industry is characterised by lofty hygiene and food safety requirements. Special framework conditions apply to the machinery itself, too: because the machines come into direct contact with food, they need to be extremely accurate and have high-quality surfaces. Workpieces such as valves, shafts or pump cases also need to be hygienic – which is why precision machining is a key process for achieving the required standards.
Keller Precision relies on outstanding infrastructure for the machinery and food industry to achieve the high level of accuracy required. With CNC 5-axis simultaneous milling/turning centres, CNC 6-sided turning/milling centres and other machines, our trained employees rely on the highest precision in the micro range, thus laying the groundwork for durable machines with the required surface quality. Thanks to its top-notch quality management approach, Keller Precision also guarantees the complete traceability of all components as well as the seamless documentation of processes and materials. Predominantly chromium-nickel-based steels are used in order to meet the high hygiene requirements of the machinery and food industry.
Specifications for
