Mandrels - Import export

Made for the gear-cutting sector Clamping solutions for the gear-cutting sector are individual and have very special requirements. Consequently, it is not easy to find the suitable clamping device, particularly in the case of high variant diversity and smaller lot sizes. The conventional solution is to use fixtures that are more or less effective. Rigid and narrow standard segmented mandrel Fortunately, this is now history. With the MANDO G211 you are relying on a standard segmented mandrel. You profit from in-stock segmented clamping bushings. The rigid and narrow mandrel with optimized tool runout contour is ideal for use in gear cutting applications. Moreover, it can also be used for gear shaping or grinding. Three end-stop levels that are placed with different proximity to the workpiece make it possible to use individual workpiece end-stops. Also a coolant connection ensures process reliability.

No problem to change-over from O.D. clamping to I.D. clamping Change-over from O.D. clamping to perfect I.D. clamping, without changing the clamping device? No problem with MANDO Adapt: Place the mandrel in the mounted clamping device, tighten three screws, and lock the mandrel in the clamping device. Reduce time In this process the mandrel engages in the coupling of the clamping device via a sophisticated mechanism, where otherwise the clamping head engages. MANDO Adapt is attractive with extreme rigidity and precision. Without adjusting For rotating products, concentricity of 0.005 mm between chuck taper and mandrel taper can be achieved. For stationary clamping devices repeatability of 0.003 mm is possible. And best of all: This can all be accomplished without adjusting.

Extremely high clamping force Often complete machining fails for lack of an effective I.D. clamping device. In many cases the jaw chuck is a makeshift solution. However, even conventional mandrels with slotted clamping sleeves quickly reach their limits in terms of accuracy, rigidity, and opening stroke. HAINBUCH segmented mandrels use state-of-the-art clamping technology that is convincing, even in the most critical applications. Segmented clamping bushing with extremely hard, wear resistant and rigid segments The central element is the vulcanized segmented clamping bushing. Because conventional clamping bushings are made of spring steel and are only annealed to spring hardness, they are »soft« and they must »bend« to clamp the workpiece. HAINBUCH segmented bushings, on the other hand, are made of case-hardened chromium-nickel-steel and have segments that are extremely hard, wear resistant and rigid.

Maximum machining capacity MAXXOS T211 is a mandrel with a hexagonal pyramid shape instead of a round taper – perfect for demanding and reliable process manufacturing. Through the hexagonal clamping pyramid, maximum transmission forces can be realized. The segmented clamping bushing with the hexagon socket sits on the clamping pyramid with an absolute positive fit, which enables maximum machining capacity with less vibration and thereby less tool wear. The lubrication, combined with its leak-tightness ensures an extremely constant production flow and therefore maximum reliability. By the way, our segmented clamping bushings offer a factory-standard run-out accuracy of ≤ 10 μm. If you need even greater precision, there are two additional levels of run-out quality to choose from. Even a run-out accuracy of ≤ 2 μm is possible upon request.

It is recommended that the cam lever is in a vertical position when the collet is positioned in the bore. The function of the clamping system was tested in bores with tolerance H7. All values for retaining force are guide values and are given without safety factor. The suitability for the respective application must be checked by the user. Advantages: Two components can be joined together without tools. The components are perfectly centred in the clamped state. The compact design means that the mandrel collet with cam lever can even be used in blind holes. There are no specific dimensional requirements for the holes. Additionally, the surfaces and design do not need to have any specific properties. Functional principle: The clamping system is inserted in the hole in the open state. At the beginning of the locking process, the mandrel collet expands and clamps itself in the lower component. The integrated disc spring assembly creates a positive down force

Again and again, coils with larger internal diameters than expected have to be processed on coilers. Here the secutex coiler sheath offers a simple and flexible solution to the problem. Enlargement of the internal diameter The handy secutex coiler sheath is simply pushed onto the coil mandrel and enlarges the radius to the required size. The timeconsuming assembly of subcomponents is no longer necessary. Prevention of dents Thanks to the high friction of the secutex material, the coil cannot slip and, in some cases, the contact pressure can be significantly reduced. The typical impressions in the initial winding layers are prevented and material wastage is significantly reduced. The secutex material is extremely wearresistant and, unlike standard rubber, is also oilresistant. The insertion tip helps thread the coils.

The machines are extremely robust and easy to operate. A selection of setups is available to process tubes of different lengths, with an operational length up to 240“ Our compact and mobile bending machines can now be controlled easily with a touch panel. This opens up new possibilities, like displaying the comparison of target and actual values for all axes. Control of the tolerance of the length and the rotation means very little involvement for the operator during the manufacturing of tubes. Accessories are available, like an integrated saw, a de-burring device, a flaring tool and a compression-fitting swaging tool.
