Air-operated self-contained chucks LVE - large through-hole APPLICATION Optimal for the end machining of large and long pipes, e.g. for the oil and gas industry (especially as front and rear chuck). TYPE Power chuck with integrated pneumatic cylinder and cylindrical centre mount. 3-jaw version with serration 90°. CUSTOMER BENEFITS Extra-large through-hole Can be easily exchanged with manual clamping chuck Compact system dimensions because it is self-contained Unobstructed bore through spindle thanks to omission of the draw tube Flange and bar machining possible without retrofitting TECHNICAL FEATURES w - Clamping and unclamping only when spindle at standstill Wedge hook system with integrated clamping cylinder Control valves maintain the clamping pressure during machining Short clamping cycle thanks to rapid and clamping stoke (optionally) Permanent monitoring of the clamping pressure while machining (optionally) Note: Other versions on request: e.g. front-end chucks for compensating clamping, compensating self-contained chucks and chucks that can be converted from selfcentering to compensating. Included in scope of delivery: Chuck, chuck and jaw mounting screws, slot nuts (without top jaws) LVE = air-operated, self-contained chuck 90° Air-operated self-contained chuck LVE Possible application Two chucks are mounted on the front and rear sides of the machine spindle. Via a selection switch on our electronic control unit DF type 525-90 combined with one pneumatic control unit LSV type 525-91 each, the two chucks can be used together or separately and also with different clamping pressures. This combinations make a high cutting capacity and high turning precision possible for the end machining of long pipes. Air-operated self-contained chucks, sizes 4001000 Characteristic for this chuck is a pneumatic piston integrated in the chuck body for generating the clamping force. To clamp or unclamp the workpiece, the compressed air is conducted to the pneumatic piston while the chuck is stationary via the distributor ring and non-return valve. The pneumatic piston is screwed to the clamping piston, with which, in turn, the base jaws are connected via a wedge hook system. An axial movement of the pneumatic piston therefore causes a radial movement of the base jaws. 6118 Distributor ring The distributor ring has the function of transferring compressed air from the outside into the chuck. This means that the distributor ring is always stationary, while the chuck rotates during workpiece machining. It is therefore mounted to the spindle box, and is therefore secured against rotating along. Special seals seal the gap between the distributor ring and chuck during the clamping operation so that the pressure can be transferred with no problems. Important: To prevent the sealing ring from being destroyed, the pressure may only be transferred when the chuck is at a standstill. Control valve The control valve has the job of securing the compressed air required for clamping in a closed system throughout machining. It automatically secures that piston side which is pressurized, whereby the compressed air of the opposite-lying piston side is unclamped automatically. The valve can be dismounted as a complete unit and is available as replacement unit. www.eshop.roehm.biz
