We offer you Advanced 3-Slide Cold Forming Machines Manufacturer. All the rolls tiltable to engage the angle of the cone. Top hydraulic assistance tiltable on the angle of the cone to hold from collapsing the formed shell. Lateral arms for plate infeed supporting very large conical formed diameters. Single pass rapidly rolling programmable save-and-repeat on NC controller. Deflection compensation of the rolls with adjustable pre-pinch stress. Calibration equipment on board the machine for the re-rolling of welded shell.
Aerospace metals can be tough to machine and form, so the widespread threading attachments used on screw machines and lathes for larger volume function struggle to meet the top quality specifications of precision threads. The force needed to kind threads on heat treated alloy steel or on exotic alloy components produced from Inconel or Titanium cannot be achieved efficiently without having using committed equipment. Tobest focuses on threads that are significantly less than 1.5 inches in diameter, but rolled threads are created on fasteners up to 5.00 inches and even bigger. It takes significant force, up to thirty or forty tons of rolling pressure generated by very huge machines, in order to move that much material. Some threads are deemed so vital that a destructive testing sampling procedure is needed to microscopically examine each pitch of a thread at 500X.
