Key type workpiece clamping chuck MADV series

precisionself-centeringcylindrical

INDEXING CHUCK WITH MANUAL CLAMPING AND INDEXING Chucks series MADV are self-centering. In version MADV jaws clamping is manual thanks to an operating key 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 slideways execution with gib allows a good sliding surface finish with possibility to recover clearances consequent to wear • indexing movement simple and reliable: conical shutter guarantees the mechanical indexing. Indexing precision ±1’30” • shaft guide system with two lines of big filled cylindrical pre-loaded roller radially and with a strong axial ball bearing axially • 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 • it can be used on every tools machine (lathe, fresatrice, etc.) • the big jaws stroke makes really the clamping of complex profiles that couldn’t be good clamping with an automatic chuck/span> • prototypes, samples and series also of big pieces realisation • a central screw supported by axial sloding bearing transmits the clamping force to the jaws Ambient temperature 5-60°C Sound emissions (sound pressure) ≤ 70 db (A) in each direction
