Tool Production with CNC-Grinding Machines

Our aim is the production of rolling tools in highest quality. We support our claim for Highest Quality Tooling by using most modern coordinates measurement technology. In order to achieve a maximum tool life we offer 3 different high alloy tool steels with different coatings. Supported by a most modern vacuum hardening technology we can find the perfect combination for every machining task.

For particular application we offer a coating of the tools in DLC, duplex process or multi-run coating system.


Tool Grinding Shop

Our grinding shop offers rolling tools made of high performance steel for sophisticated demands of threading or serration. We especially recommend our PSS style grinded tools for immediate track finding. We offer you free Palettes for the transport of your Tools.

Vacuum Heat Treatment

Highly precise parts which need to have a clean and bright surface often show a disposition for distortion. These parts are predestinated for the hardening in the vacuum furnace to receive best results. Quenching is carried out by a gas flow under high pressure. The pression can be modified considerably and as a result the quenching can be regulated softly. The tools remain bright as there is no oxidation under vacuum.

Vacuum Heat Treatment

Plasma nitriding system for high quality treatments

Highest demands and expectations will be realized by this way of heat treatment:

  • stability and accuracy
  • surfaces which are metallic bright
  • higher life time of the tools
  • accurate documentation of the running process cycle (even of difficult ones)
  • absolutely repeatable treatments
Our most recent innovation in vacuum heat treatment:
  • Full vacuum
  • For special alloying (PW3000)
  • Cooling
  • Hardening and deep freezing in just one unit including a complete documentation for best microstructure and corrosion resistance
