Change over from O.D. clamping to jaw clamping or centric clamping in 2 minutes without clamping device change-over and without having to align ? No problem, with the jaw modules. Because the basic unit, into which the jaw module is inserted, is a HAINBUCH chuck or stationary chuck. If at times the clamping head reaches its limits because it must clamp a larger area, then use one of the jaw modules.
The 3-jaw module is best suited for round workpieces, and if you have cubic workpieces, then rely on the 2-jaw module. This means that for a large parts spectrum you are completely flexible and always have the solution that is ideally suited for the respective clamping situation.
Adaptation for centric clamping
Standardized quick change-over interface for small spindles
Up to 25 % more clamping force and higher output – with the same clamping cylinder that is used to actuate our SPANNTOP chucks. The pyramid arrangement of glide surfaces makes it possible. The clamping head rests with full-surface contact in the TOPlus chuck body – even with large workpiece tolerances.
Insensitive to dirt
In addition this geometry ensures that TOPlus is significantly less sensitive to contamination than previous chuck/clamping head solutions, and with a concentric precision of approx. 0.015 mm [for chuck size 65]! Thus TOPlus is even better suited for raw material, cast and forged parts, as well as fi ne-particle non-ferrous metals such as brass. Therefore, all-round optimized values make the chuck an ideal partner for modern manufacturing strategies and state-of-the-art machine tools.
TOPlus – simply revolutionary!
Standard or machine specific, which chuck fits?
In 90 % of all cases, you will find what you are looking for with our
standard chucks, that fit for the following brands, such as:
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.
Radial clamping with pull-back effect
Whether you design the machine connection on your own, or whether you want a complete solution from us extending to the quick change-over system, in every case you profit from radial clamping with pull-back effect – and this incredibly increases the rigid clamping. Therefore you have complete control of accuracy and vibration.
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. Moreover, the segmented clamping bushing with the hexagon socket sits on the clamping pyramid with an absolute positive fit and thus enables maximum machining capacity with less vibration and thereby less tool wear. The lubrication, combined with its leak-tight-ness ensures an extremely constant production flow and therefore maximum reliability. By the way, our segmented clamping bushings offer a concentric precision of ≤ 10 μm. If you need even greater precision, there are two additional levels of concentricity quality to choose from. Even a concentric precision of ≤ 2 μm is on request possible.
Choose your suitable mandrel
Overall the mandrel covers a clamping diameter range from 18 to 100 mm. The clamping ranges of the respective sizes are designed to overlap. Depending on the clamping diameter, you can choose from two to three different mandrel sizes. The larger mandrel means more stability and rigidity, the smaller mandrel can cover a greater quantity of smaller workpieces if necessary.
Those who place more value on process reliability and optimum torque transmissions are very happy with the MAXXOS T211.
MAXXOS mandrel with hexagonal pyramid shape reduces your costs!
Extended variant with many more clamping possibilities
MANOK plus, the extended variant of our manual MANOK stationary chuck differs through use of adaptation elements. For example, many more clamping possibilities are available to you in combination with the MANDO Adapt mandrel-in-chuck or the jaw module for even larger clamping diameters.
And most recent: Due to the optional lightweight CFRP design, with the MANOK plus CFK you can save half of the weight. The lightweights are easy to set-up and particularly well-suited for milling machines and machining centers with small load weights. Plus they protect machine components, which ultimately helps the machine accuracy. When loading manually or with a handling system, often the only possible solution is a lightweight stationary chuck.
Depending on size, combined with all adaptations
5-axis machining or rational multiple clamping – with HYDROK we offer a hydraulically actuated stationary chuck that provides even more implementation possibilities. Depending on size – you can use it with all clamping device adaptations, such as the MANDO Adapt mandrel-in-clamping device or with the jaw module. Thus in the future you can also rely completely on the intelligent HAINBUCH modular system, even for your stationary clamping device.
Multiple clamping in confined spaces
The smallest of the group: HYDROK 40 SE and 32 RD. Their modular base plates can be easily fitted together and enables multiple clamping with incredible holding forces in the most confined spaces. And with an additional tandem cylinder you can even generate the full clamping force with a weaker hydraulic unit.
Whether lathe or machining center
Complete machining made easy: You cannot only use our MANDO and MAXXOS segmented mandrels on the lathe, you can also use them in stationary mode. Simply screw the mandrel onto the ms dock [manually actuated] or hs dock [hydraulically actuated] and you can clamp your workpiece from the inside, stationary mode. Precise, without vibration and with minimum set-up effort. The extremely wear-resistant segmented clamping bushing of case-hardened chromium-nickel-steel with the rubber between the segments, especially developed by HAINBUCH, makes it possible.
Manual actuating unit ms dock
The hand-actuated ms dock in conjunction with stationary MANDO and MAXXOS segmented mandrels is ideal for machining centers, measuring machines, radial drill presses, parallel and angle plate clamping or for clamping on dividing heads. The version ms dock rotating can be used on turning and grinding machines until RPM 1/min.
Hydraulic actuating unit hs dock
hs dock is an absolute powerhouse that enables hydraulic implementation of MANDO and MAXXOS segmented mandrels on machining centers. Media supply can be freely selected. It is actuated either from the side or via a base plate from below. Perfect when automation is involved.
Some examples of our many clamping solutions
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.
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.
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.
MANDO Adapt is available in 3 variants:
Clamp difficult or easily deformable workpieces
In daily use you are optimally equipped with the TOPlus or SPANNTOP chucks. However, there are always components that are difficult to clamp due to the contour, or that will be deformed through radial clamping. So what is required is an axial chuck, which in addition can also be set-up very fast.
Clamp axially on a neodymium magnet
The answer: HAINBUCH magnet module. With the magnet module you can clamp components axially on a neodymium magnet. The HAINBUCH magnet module is set-up in only 30 seconds. Your basic clamping device is already mounted. You exchange the clamping head that is included in the scope of delivery. When clamping, the magnetic clamping device is pulled onto the flat contact area of your basic clamping device.
Planar change-over accuracy of 2 μm
If, after initial installation, the magnet module is planed flat and the install position is marked, a planar change-over accuracy of 2 μm can be achieved. The workpiece itself is clamped by hand on the magnet.
It is useful, when you can machine a workpiece over its entire length. It is even more practical, if in addition the re-clamping can be omitted. Firstly, this increases concentric precision, secondly, geometric tolerances are »stabilized«, and thirdly, our face driver adaption is also assembled 1-2-3. Simply insert it in the clamping device, tighten the three screws, and that’s it! Our CENTREX interface ensures perfect concentricity.
Segmented clamping bushings RD
Made of case-hardened chromium-nickel-steel [60 HRC], highly elastic, vibration dampening and with a large opening stroke for easy loading of workpieces.
