Any company that is involved with workpiece milling, has access to LANG Technik’s Makro-Grip technology which provides a workholding solution to almost any clamping requirement from raw material to the finished workpiece. The company has been responsible for numerous workholding innovations that reduce costly changeover time, reduce operator workload and maximise productivity.

One of the many benefits of using LANG Technik products is their patented Quick Point zero-point clamping system. This allows for a one time installation – once the base plate is mounted and aligned to the machine tool table and the zero point is defined, workpieces and fixtures can be built quickly and accurately. The zero-point system provides a huge boost to productivity, reducing changeover time from 1-2 hours to around five minutes.

The Makro-Grip range of vises are the Makro-4 Grip and Makro-Grip Ultra. The Makro-4Grip allows LANG’s stamping technology to now be utilised for round parts. Makro-Grip Ultra now allows manufacturers to clamp a variety of large parts for which previously no workholding solution existed

Two recent additions to LANG’s respected Makro-Grip range of vises are the Makro-4 Grip and Makro-Grip Ultra. The Makro-4Grip allows LANG’s stamping technology to now be utilised for round parts. The stamping is a patented form-closure technology which provides the highest holding power for 5-face machining worldwide. Often referred to as pre-stamping, it involves the workpiece being stamped outside of the machine tool with up to 20 tons of hydraulic pressure. Clamping scenarios that require high holding power, no work stop in the machining area or where the danger of workpiece deformation exists, can be mastered with the stamping process. Makro-Grip stamping technology provides tremendous material savings due to minimal clamping edge requirements.

LANG Technik’s stamping technology is still the benchmark when it comes to processing raw parts in 5-axis machining. The Makro-4Grip system consists of universal stamping jaws including stamping inserts for individual positioning as well as matching clamping jaws suitable for all sizes of Makro-Grip vises. The jaws grip the pre-stamped part in four indentations at a clamping height of just 3mm and cover a clamping range from 36mm to 300mm.

The other recent workholding innovation LANG Technik has added to their portfolio is the Makro-Grip Ultra; this innovative clamping system allows clamping of large parts. Thanks to the expandability of its modules Makro-Grip Ultra is capable of clamping single or multiple parts of 810mm length and beyond safely. This capability pushes workholding to new heights and is particularly suitable for mould making and clamping applications of flat and large parts including deformation-sensitive parts. Different system heights, individually expandable clamping ranges, interchangeable clamping jaw types and a range of useful accessories add to the versatility of the vise.

Makro-Grip Ultra is extremely flexible and equally capable of clamping, cubic, round or asymmetrical workpieces. Manufacturers are now able to clamp large, flat workpieces concentrically and combined with the zero-point clamping system allows for changeover within seconds, making it possible to process numerous parts in next to no time.

The Quick Point Zero Point plates work mechanically without the need of hydraulics or pneumatic and offer repeatability of 5µm

Makro-Grip Ultra now allows manufacturers to clamp a variety of large parts for which previously no workholding solution existed. Through its wide range of possible configurations the modular system covers practically any imaginable clamping application.

In combination with the Zero Point plates set up times can be reduced by 90% with very little clocking and probing necessary. This kind of time savings and quick change over time allow for increased spindle-on times with a rapid ROI. The mechanical, self-centring vises offer a high degree of rigidity, are basically maintenance and wear free with very few replacement parts, should an accident happen.

The Quick Point Zero Point plates work mechanically without the need of hydraulics or pneumatic and offer repeatability of 5µm. There is a wide range of different sizes available.

The Makro-Grip vise range also includes the Dual-Clamping vise, the Makro-Grip Automation and the Profilo Clamping vise – a clamping system for all shaped parts allowing for the use of different types of profile jaws on one vise body.

The Universal Avanti vise offers great handling characteristics and enormous set-up time savings thanks to a quick jaw exchange system. LANG Technik AVANTI is a patented quick change system to exchange soft jaws inside the machine. The jaws clip onto the base jaws and are locked with one clamping screw only. The quick change design guarantees highest exchange accuracy and change-over of soft jaws only takes a few seconds.
