Internal burnishing tool 10 - 20 kN, max. 1400 N/mm2, ø 10 - 250 mm | EFxx series

external

For use on conventional or CNC lathe. Complete machining with one chucking. Can be used as right or left-handed tool. Both directions of rotation possible. Characteristics: For machining of turned parts’ fillets, like shafts, screws, tension bars, torsion bars. Deep rolling by plunging method. A floating roller. Rolling force monitoring with gauge or inductive position measuring system. Basic construction: Type EF deep rolling tools consist of a tool body equipped with a shank, a spring assembly that allows the roller head to move with no play and very low friction, and a dial gauge that indicates the burnishing force as measured by spring defl ection. An optional device transmits the values by cable or wireless signal to an external indicator. The roller head is attached to the flexible, spring-loaded section of the tool body. The flexible roller retainer moves in response to the radial or axial rolling forces on either side of the tool. The roller is guided by a cage and supported by a support body with large-scale needle bearings.
