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,” said Dimac Managing Director, Paul Fowler.
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.
“Makro-Grip stamping technology provides tremendous material savings due to minimal clamping edge requirements; the new Makro- 4Grip means that any company that is involved with workpiece milling of round parts can now benefit from this technology easily and cost efficiently,“ said Mr Fowler.
“Lang’s stamping technology is still the benchmark when it comes to processing raw parts in 5-axis machining,” Mr Fowler added.
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 vices. 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 810 mm 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,” Mr Fowler said.
“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,” Mr Fowler went on to say.
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.
Another unique product in the Lang Technik range is the Cleaning Fan. The fan automatically cleans the machine table, pallet and/or workpieces after the machining process is complete.
