self-centeringcylindricalsteel

INDEXING CHUCK WITH DRAW BAR CLAMPING AND MANUAL INDEXING MADT chucks series are self-centering. Jaws clamping is automatic trough a draw rod and a rear cylinder and manual indexing system. • made in special high resistance hardened and cementing 60HRC steel UNI18NiCrMo5, to maintain a high degree of precision, reliability and quality • jaws slides execution with gib allows good sliding surface finish with possibility to recover clearances consequent to wear • shaft guide system with two lines of big filled cylindrical pre-loaded radial rollers and with an axially strong ball bearing • indexing movement simple and reliable: a conical shutter guarantees the mechanical indexing. Indexing precision ±1’30” • seals against contamination by coolant, chips and dust • constant and long lasting precision • easy installation to the machine • standard with 4 indexing 90° + 1 indexing 45°. • On request special indexing positions available (8×45°, 6×60°) ADVANTAGES • self-centering clamping • big clamping capacity • versions with long jaw for workpieces that need a big radius of revolution • quick and easy installation to the machine, it is request only the connection to the hydraulic cylinder on the lathe • manufacturing of different pieces and also of small series • workpieces with big radius of revolution and flanges with big diameter • could be apply in the same machine with a conventional 3 jaws power chuck thanks to the quick retooling increasing unit flexibility and productivity • the indexing device allowing a quick change between the multiple working axes • good tools accessibility thanks to the chuck shape Ambient temperature 5-60°C
