Ready for any clamping application

Modularity, flexibility and precision - Makro•Grip® Ultra
combines all these attributes in totally new dimensions.

Modular design

The modularity and small number of components, as well as the consistent Quick-Point® 96 zero-point grid allow to change the clamping setup immediately.

Innovative jaw adjustment

By removing the threaded cap with a magnetic handle the clamping jaw position can be changed in a short timescale without actuating the spindle, independently from other clamping jaws. By that, even asymmetrical parts can be clamped.

Easy to maintain

The Makro•Grip® Ultra spindle is solely fitted between two high-precision centering plates which allows for a quick and comfortable setup process. Clamping jaws and spindles are removed easily which simplifies cleaning and maintenance after and in between machining processes.

Quick to set up

The quick jaw adjustment which is made possible by threaded caps, allows quick changes between different jaw types.

Various center options

In order to offer an additional resting surface and to limit possible vibrations, a support jaw can be mounted to the center of the clamping system. Center jaws are available for clamping multiple parts. In this case centering plates are used which makes it possible to clamp workpieces with a 4 mm variance in length.

Low-vibration clamping

A specific hydraulic screw jack and spacers to match the respective height of the base bodies have a supporting effect on the clamping process which is particularly important with flat and wide material.

All-around machining

Thanks to the jaw variety the operator can choose between different approaches and configurations for the first and second operation depending on the requirements of the workpiece.

Multiple clamping

Center jaws can be mounted for clamping multiple parts simultaneously – both with serration or plain clamping surface.

Asymmetrical parts

Each clamping jaw is individually secured by a threaded cap and thus can be moved indepentently from other clamping jaws. By that, asymmetrical and pre-machined profiles can be clamped.

Manual and automated manufacturing

In a flexible, combined production (automated batch production of small parts by night, large parts manually during the day) an increased machine utilization can have a positive effect on unit costs.

Makro•Grip® Ultra Stamping Unit

The stamping technology is now available for large parts. The form-closure effect which is made possible by pre-stamping guarantees highest holding forces at low tightening torque.

Features:
  • Designed as a dual-stamping unit
  • 3 different sizes for stamping parts up to 420 / 630 / 810 mm
  • Flexible positioning in the 96 mm grid
To product page

Further information about the Makro•Grip® Ultra stamping unit:

The stamping technology

Form-Closure Technology refers to a technology in which the workpiece to be clamped is “pre-stamped” with a defined contour under high stamping pressure (up to 20 t) outside of the machine tool, before it is clamped in the clamping device. Due to the great amount of advantages for the actual clamping process through “pre-stamping”, the Makro•Grip® technology is considered a benchmark in the 5-sided machining of blanks and absolutely beneficial to automated manufacturing.

More information
Why pre-stamp a workpiece?

The form-closure effect between the gripping serration of the clamping jaws and stamping indentation guarantees highest holding forces and maximum process reliability at a very low clamping pressure. This practically eliminates any material deformation which is crucial to clamping flat and deformation-sensitive material and a key factor in achieving the desired milling quality. The stamping technology completes the Makro•Grip® Ultra system and raises the quality of plate and large part clamping to a new level.

Success Stories

Clamping with Makro•Grip® Ultra pays off according to our customers

Makro•Grip® Ultra offers us the opportunity to clamp components, for which we had no solution so far. I was especially impressed by how fast we were able to solve an existing clamping tasks. From getting to know the system to the first chip in our production it did not even take 3 hours.

Simon Großmann, Großmann Präzisionstechnik, 73235 Weilheim unter Teck, Germany

With the new system by LANG we are now able to clamp large workpieces concentrically. The modularity of Makro•Grip® Ultra combined with the zero-point clamping system made it possible to process various parts in no time. The quick jaw adjustment is designed to be very user-friendly. Also the stamping technology was put to test successfully once again. In this application we clamped a steel block with a height of 350 mm at a clamping depth of only 5 mm. Roughing was done using a high feed milling cutter. With Avanti top jaws the second operation is realized in a few simple steps. In terms of accuracy the LANG system leaves nothing to be desired.

Michael Kupke, MKTec Meisterbetrieb, 86567 Hilgertshausen, Germany

Due to the high level of vertical integration of small batch sizes, set-up times have a significant impact on the economic efficiency in our prototype department. At the same time, the frequent change between different clamping situations demands a lot of flexibility of our workholding. This is exactly where the advantages of the zero-point clamping system and the very modular Makro•Grip® Ultra become apparent for us. Thanks to its modularity, we can always adapt the system exactly to our requirements and cover the majority of parts with basically the same workholding system. We therefore have our setup times under control at all times.
