the Stamping Technology by LANG Technik

Stamping Technology

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.

Through initial recommendations from the formula 1 industry, we equipped our first 5 axis machine with LANG's Makro•Grip® and their associated zero-point system. Needless to say, we've never looked back. The Makro•Grip® vises offers great work access around the material stock. The high clamping force in combination with indentations by the serrated jaws has never failed to hold our parts firmly. The repeatability of the self-centering vises in combination with the zero-point system ensures we can offer consistent quality components to our customers.

I switched over to LANG Technik workholding products one year ago. I was immediately impressed by the quality and precision of LANG products. My favorite feature by far is the Makro•Grip® system. I’ve noticed a tremendous increase in part stability due to the minimal clamping pressure required to accurately retain parts. Eliminating the need for stock preparation or dovetailing in a CNC machine has been a gamechanger as well. Efficiency has increased considerably. I look forward to growing my collection of LANG workholding products!

Eddie Casanueva, Nueva Precision, Milliken USA

We have used LANG Makro•Grip® vises for many years now and they have provided us extra efficiency and safety in workholding. It is good to see LANG Technik constantly developing new product and improving existing ones. It assures us that we have chosen right partner for our workholding solution.

Kristjan Joost, Afterone ÖU, Tartu Estland

We are absolutely convinced by LANG’s stamping technology and the Makro•Grip® vises. To us the pre-stamping process of raw material has several advantages compared to simply clamping with conventional gripping jaws. As an example: Through an adjustment of the stamping pressure, the stamping contour pattern can be realised across the entire jaw width, even when the raw material is not a 100% parallel. This ensures an absolutely safe clamping process with the 5-axis vise, even with strong machining forces and parts with a huge overhang. Furthermore, we do not need an end stop, as the stamping contour determines the position in the vise. This guarantees us optimal accessibility from all sides.
