224 AXN® Automatic indexing chuck Automatic indexing chuck Ø 210 - 1250 mm Unique features Hardened and ground body and internal parts designed to avoid deformation, ensuring rigidity and accuracy. Easy installation to the machine. Indexing movement during spindle rotation, allowing a quick change between the multiple working axes. Indexing and clamping mechanism constantly oil lubricated and supported by strong systems of roller bearings. Very high maximum speed, with centrifugal force compensation system, for higher productivity performance. Very simple hydraulic system based on just 4 hoses, 2 for the indexing mechanism and 2 for the clamping piston. Internal mechanisms fully protected against contamination by coolant, chips and dust. Constant and automatic control of the position of the part and other working parameters by the C.N.C. of the machine, or by a separate electronic interface. Application/customer benefits • Fully automated and high productivity machining of components with orthogonal axis or with 45°, 60° or 120° axis • High productivity for machining of workpieces like valve bodies, spiders or fittings (see picture below) at high position accuracy AXN: Automatic indexing chuck with hydraulic clamping and indexing Technical features • Rigid holding of the workpiece at high revolutions allowing high chip removal rates • High positioning and repeatability precision • Reliable indexing system with constant oil lubricated internal mechanism • Constant and automatic in-process controls for extremely safe machining • proofline® chucks = fully sealed - low maintenance Components supplied on request Adapter parts and clamping jaws General operating diagram 4 wired “M” functions + Relays position achieved + pressure OK the turning operation on the achieved position can start position request position command position signals pressure levels 2 pieces 4 / 2 solenoid valves with fixed position + 3 pressure switches hydraulic connections: - 2 for indexing - 2 for clamping - 1 manifold drain rotating oil manifold 4 tubes for oil supply (clamping and indexing) stroke control rod 3 or 4 proximity switches ELECTRONIC INTERFACE (indexing drive and control) MACHINE C.N.C.
