With a revised stamping unit (featuring a new type of serration) and a complete, additional series of five-axis vices, Lang Technik say the company continues to develop its ‘original’. According to Lang, the company’s stamping technology has been setting the bar for top-notch quality in five-axis machining through its form-fit clamping philosophy for years. Now, Makro•Grip FS is taking this to a whole new level with even more impressive milling performance. 

The abbreviation FS stands for fully serrated/full serration and describes the new, continuous holding serration on the clamping jaws of the new-generation vice.  The new form-fit between the continuous holding serration and the matching contour in the pre-stamped workpiece blank increases holding force by up to 60%, depending on the material and stamping depth. For machining, this means even more reliability and safety in workpiece clamping, which in turn allows higher cutting performance and faster milling processes.

Lang’s stamping units with adapted stamping serrations impress with numerous new features, making operation even easier and more effective. For example, the process of setting the stamping pressure can be significantly accelerated thanks to the new stamping depth gauge. The setting is now data-based by reading off the dial gauge instead of visually checking the workpiece.

A new centring unit also makes it child’s play to insert the workpiece blank exactly in the centre, reports Lang.

Lang’s five-axis vices of the FS series are available in all previously known sizes and models, and also in a new mini version: the Makro•Grip micro. The FS series will initially run alongside the established Makro•Grip series, but is expected to replace it in the medium term due to its performance advantages.

It is now possible to retrofit the Röhm iJaw, which features sensor technology and wireless data transmission to measure clamping force in real time during machining, to all turning machines. There is no need to integrate the technology into the machine’s control system.

“With iJaw, we are effectively revolutionising the machining process,” says Gerhard Glanz, CEO of Röhm GmbH. “This is because real-time measurement of the clamping force during the machining process provides the user with a whole range of benefits. The advantages start with higher machine availability because of a reduction in set-up times and faster machining processes. The result is lower part costs on the one hand and increased component quality on the other. Overall, sensor-controlled workpiece machining is, of course, much safer than conventional manual clamping by feel.”

Gone are the days when operators would have to set the clamping force higher than necessary in order to ‘play it safe’.

“Especially with thin-walled components or sensitive surfaces, this is known to be counter-productive because having too high a clamping force quickly leads to deformation or even crushing of the workpiece,” says Glanz. “With exact knowledge of the applied clamping forces, you can significantly reduce rejects.”

This is how the iJaw works: an integrated sensor detects the forces introduced into the jaw, with data processed accordingly. The iJaw measures not only the actual applied forces of the internal and external clamping but also its own temperature. The system constantly displays the charging status of the battery. Röhm’s iJaw measures in real-time during machining.
