Our rolling dies are manufactured under rigorous quality control, to be used in all types of thread rolling machines and and heads used in lathes.
Rollind dies for plunge threading, through feed (continuous, normal and fast), for burnishing, knurling and splines.
They are manufactured in diameters from 50 mm. up to 300 mm., with very high quality materials. Chrome vanadium alloy steels, specially developed with high wear resistance as well as a high elasticity index.
The grinding of the profiles is carried out on thread grinding machines, developed specifically for these jobs, which allow all the profiles to be made in accordance with the standards or with the instructions of each customers.
The verification is carried out by optical control and a profile projector.
Once controlled and verified, the rolling dies are subjected to a stabilization treatment in the oven to eliminate the stresses accumulated during grinding, achieving greater resistance to breakage.
