Since many decades thread rolling machines with Planetary thread rolling dies with their universal workpiece range are most productive machine tools for coldforming especially for rolling of headed screws.
This process is also usable for workpieces with higher tensile strength or for special nails. Even bigger dimensions for this 100% grinded dies can be ordered.
A big challenge is always grinding of outer segment dies. Their different radius designs on one hand is needed for feed on the other hand for forming of thread.
Profiroll SRS for Planetary Dies
Totally new is the possibility to intregrate the SRS-System for trace matching into the planetary dies design. There the position of internal round dies is always known.
Because of defined position these dies can be used several times without new trace finding.
Depending on diameter and length of workpieces an output up to 1500pcs. per minute can be achieved with highest die lifetime due to Profiroll design.
Isn't this something for you?!
