We have more than 70 years of experience in producing cold deformation rolls for all types of profiles.
Our unique patented system PSS (system synchronized roll nip) minimizes the time of preparation and startup of the rolls in the process of thread rolling. In this way, the cost in time and complicated preparation is canceled.
Threaded – Burnishing
Knurls – Splines
Finned tubes – special profiles
Plongée – Through-feed: normal, Extra fast, keep it going (multiple rings), mixed.
Planetary dies - rolls attached to thread heads
The grinding of the profiles of rolls Grinding is done in CNC, profiling work accurately and at high speed using grinding wheels, thus imparting roll correct and accurate profile.
Our goal is the production of roll sets of the highest quality. We use advanced technology to coordinate measurement. We offer 3 types of materials for longer life:
life for roller set M10x1, by material, material with threading 42 Cr Mo4:
Tools support the production of high quality using the latest technology for measuring coordinates.
For the longer lifetime, we offer 3 different types of steel alloys of very high quality with various coatings. Applying the latest technology tempered vacuum seek the perfect combination for any machining work.
We have developed special radio method to reduce the notch effect at the end of the threaded effectively. So roll sets also have a higher durability.
Vacuum heat treatment
Highly precise parts which need to have a clean and bright surface often show a disposition for distortion. These parts are predestined for treatment give a vacuum oven for 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.
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:
For special alloying (PW3000)
Hardening and deep freezing in just one unit, including a complete documentation for best microstructure and corrosion resistance
