Makro•Grip® Raw Part Clamping
Compact and unmatched holding power for the 5-sided machining of blanks and unfinished parts
External pre-stamping makes it possible to hold a workpiece in the Makro•Grip® 5-Axis Vise with low clamping pressure in a process-safe manner. Deformation and distortion of the material during clamping and release are thus excluded and wear on the clamping device is reduced to a minimum.
Its compact design and high holding forces due to the form-fit clamping make the 5-Axis Vise the ideal workholding device in the 5-sided machining of raw parts.

Makro•Grip® Stamping Technology
„The Original“ – the Stamping Technology by LANG Technik
The Stamping Technology was invented by LANG nearly 20 years ago and can be regarded as the heart of the Makro•Grip® workholding. It guarantees highest holding forces and ideal accessibility in 5-axis machining of blanks. The pre-stamping of workpiece blanks favours a variety of factors that have a positive effect on process reliability and cost-efficient production, which is why the Makro•Grip® technology is considered the benchmark in today's workholding. During the pre-stamping process workpieces are prepared with a defined contour at an external stamping unit under high pressure, which generates a form-fit between serrated jaws of the Makro•Grip® 5-Axis Vise and the stamping contour when clamping the workpiece. As pre-stamping is conducted externally, no additional machine capacities have to be spent in order to prepare the workpiece. The process only takes about 5 seconds - but these 5 seconds will forever change your manufacturing processes and the way you clamp your workpieces.
Why pre-stamping a workpiece blank?
Conventional vises penetrate the workpiece blank with high forces exposing both, the vise and the workpiece to high strains. The Makro•Grip® technology however uses a different approach. By pre-stamping the workpiece blank with up to 20 tons of pressure and preparing it with a defined contour, the forces are already applied before the actual clamping process. Once it is prepared with the contour (pyramid-shaped truncated indents), the Makro•Grip® 5-Axis Vise can hold the workpiece by form-fit, absolutely gently and securely with low clamping pressure - always with the same clamping jaws, regardless of the material and the hardness. Due to the low clamping pressure, distortion on the workpiece as well as wear on the vise can virtually be ruled out. Even with high-tensile material an always consistent clamping quality is guaranteed, which is crucial to achieving the desired quality of the machined workpiece.
