Hydraulic Expanding Mandrels
Hydraulic Expanding Mandrels
Hydraulic expanding holding devices have opened new means to handle the most intricate clamping situations thoughtfully. On one hand these reduce cost and improve quality of machining and inspection, while on the other hand, these solve the most complicated clamping problems.
?
There is no damage to the clamping surface, though the clamping force is a maximum of 5kg/mm2. Furthermore, the concentric holding design innate property provides minimum TIR ? under 5 microns. Simple actuation reduces mounting and dismounting.
?
Hydraulic expanding holding devices have no loose components (collects or liner) making pressure coolant applications on chucks direct and efficient. Flexibility in design and application of hydraulically controlled holding devices lies in the fact that they can be adopted to perform any machining operation like finish turning, grinding, boring, drilling, gear cutting, gear finishing, etc. Their design can be extended to clamp on blind bores. Splinted bores could be located on the major diameter, minor diameter of pitch-line diameter.?
?
Hydraulic expanding arbors and chucks could be applied successfully in inspection of components accurately. Many inspection requirements are possible by mechanical means could be solved by using hydraulic devices. The greatest advantages of these devices are that these don?t involve any additional skill and require low maintenance cost.?
Product & Technology News
Right from the most severe machining operations and critical balancing conditions to the most intricate inspection procedure, our products have solutions for all the complexities. Operation is fast and reliable on special automated equipment as well as on general-purpose machinery for short production runs.
| Accuracies | 0.010 mm T.I.R. at 50 mm projection for chucks 0.005 mm T.I.R. between centers for mandrels |
| Limits of expansion/contraction | 0.20% of the diameter when length to diameter ratio is a minimum of one |
| Diameters | 6 mm diameter minimum, no practical limit on maximum diameter |
- The advent of CONCEPT- hydraulic clamping work holding devices 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 aII 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 pressure coolant applications on chucks direct and efficient. Presenting of a hydraulic fixture is also simplified as there is no axia I movement while clamping. Flexibility in design and application of hydraulically controlled holding devices lies in the fact that they can be adopted to perform any finishing machining operation - turning, milling, boring, drilling, fixture location, gear cutting, gear shaving, gear grinding, gear honing, dynamic balancing etc. Design flexibility 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 advantages of these devices
