Expanding mandrels
Mandrel type 213
Ideal for small clamping diameters and slender mandreI bodies

This mandrel type is ideal for small clamping Ø and extremely slender mandrel bodies. In comparison with our MANDO T211 with draw bolt, the segmented clamping bushing is not released via ejector pins in the mandrel body; rather it is coupled in on the upper end of the draw bolt.

Key advantages

• Slim mandrel body at low clamping Ø possible
• Segmented clamping bushing coupled in draw bolt, i.e. a stiffer mandrel body is possible
• Workpiece stabilization through axial draw force applied against the workpiece end-stop
• Vibration dampening due to vulcanized segmented clamping bushings
• Large clamping range due to vulcanized clamping elements

Mandrel MANDO T211
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. All contact surfaces are completely ground in one operation guaranteeing optimum concentricity.

Efficient and economical

• Extremely high clamping force even at the smallest clamping Ø
• Clamping range Ø 8 – 200 mm
• Large clamping range and vibration dampening due to vulcanized clamping elements
• Standard segmented clamping bushings and workpiece end-stops for machining to size available

Advantages

• Workpiece stabilization through axial draw force applied against the workpiece end-stop
• Less expensive segmented clamping bushings and end-stops compared to MANDO T212

Mandrel MANDO G
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.

The miracle weapon for gears

Advantages:

• Stiff and slim mandrel with optimized tooling contour
• Ideal for gear hobbing but it can also be used for gear cutting or gear grinding
• Quick-change interface is available


The best choice for gear cutting

• Segmented mandrel with slim interference contour
• Rigid radial clamping with pull-back effect
• Large clamping range and vibration dampening due to vulcanized clamping elements
• Three end-stop levels
• Integrated flushing channels

The angular and Beary mandrel

MAXXOS T211 a mandrel with hexagonal pyramid shape instead of a circular cone - is ideal for a sophisticated and reliable production. Maximum transmission power can be realized by the hexagonal clamping pyramid. Also, sits the segmented clamping bushing with the hexagon socket in each clamping position absolutely positively on the clamping pyramid and allows for highest machining capacity in less vibration and thus less tool wear. The lubrication, in connection with the leak, guaranteed a very constant current production and thus reliability. By House our segmented clamping bushings offer by the way a concentricity of ≤ 10 μ m. should you need it more precisely, you have two more Rundlaufgüten to choose from. Even a concentricity of ≤ 2 μ m is possible on request.

• Interior clamping PIN for clamping diameter 18 to 100 mm in stock
• high transmissible torques and clamping forces
• reduced tool wear due to high rigidity
• Precision ≤ 0.01 mm / 0,007 mm possible
• Precision ≤ 0.002 mm on request
• dirt-resistant by hexagonal pyramid shape
• process-safe production

Advantages

• hexagonal pyramid shape, ideal for a sophisticated and reliable manufacturing
• Realization of maximum transmission power
• highest machining capacity in less vibration and thus less tool wear
• up to 155% more transmissible torques and up to 57% higher bending stiffness compared to the round mandrel
