Hydraulic Expanding Mandrels

We are offering hydraulic expanding mandrels.
concept-hydraulic clamping systems
the advent of concept-hydraulic clamping system opens new ways in mastering the most difficult situation with uncompromising thoroughness. Sophisticated technology, perfect construction and special materials make the clamping devices a generation ahead of the conventional work holding fixtures in clamping force, clamping accuracy and load torque.
whereas remarkable technical advance has been made on machines and machine tools, clamping fixtures have scarcely changed. Hence, the available productivity and precision of the machine was not transferred to the component to be machined to a great extent. Concept-hydraulic arbors and chucks offer an optimum solution to this weak link in a machining chain.
concept-hydraulic holding devices on the one hand reduce cost and improve quality in almost all areas of machining and inspection while on the other solve the most difficult clamping problems.
the very high repeatability and reliability factors reduce rejections to a minimum. There is no deformation of work piece or damage to the clamping surface - though the clamping force is a maximum of 5 kg/mm - as the clamping force is transmitted evenly to the entire clamping surface. This means even very short or thin walled components could be securely clamped with the least danger of canting or deformation. Further more the concentric holding design inherent property provides minimum tir - under 5 microns. Simple actuation reduces mounting and dismounting time - no tapered mandrel, no hammering, no arbor press. Symmetrical mounting allows mounting of several piece parts.
concept-hydraulic holding devices have no loose components (collects or liners) making pres¬sure coolant applications on chucks direct and efficient. Presenting of a hydraulic fixture is also simplified as there is no axial move¬ment while clamping.
flexibility in design and application of hydraulically controlled holding devices lies in the fact that they can be adopted to perform any machining operation - turning, copy turning, boring, drilling, gear cutting, gear finishing, etc their design can be extended to clamp on blind bores. Splined or threaded bores could be located on the major diameter, minor diameter or pitch-line diameter.
concept-hydraulic expanding arbors and chucks could be applied successfully in inspection of components accurately. Many an inspection requirement not possible by mechanical means could be solved by using hydraulic devices.
no requirement of additional skill and low maintenance cost are the major advan¬tages of these devices.
engineering
a selection of arbors and chucks in standard sizes and average bearing lengths are generally available from stock. (write to us for a copy of our standard products catalogue.) in most cases, however, concept tooling is tailored to the specific job in the accuracy range specified. All we need is a print of the part or parts involved with locating surfaces and tolerances indicated. An outline of the operations performed with pertinent machining data or inspection techniques should accompany your enquiry.
your enquiry will be carefully and completely analyzed with our recommendations and quotation offered for your consideration.
we welcome your specific problem and will be happy to offer our recommendations to suit your requirements.
