Full precision on five axes

The new RVM 5-axis vice from Röhm is flexible in its connection to the machine table and workpiece, fast and precise, easy to handle and accessible from all sides.

The manual mechanically actuated component clamp (without power transmission) is designed as an eccentric single clamp. It has a fixed and a movable jaw and is suitable for 5-axis machining of a wide variety of workpieces from a single clamping process.

"With the RVM, we have really hit the jackpot, because it not only speeds up the processes on the milling machine but also increases precision during machining," says Gerhard Glanz, CEO of Röhm GmbH.

The new component vice can be attached to the machine table with the aid of fastening screws directly through the base body. Alignment is then carried out via tenons. This applies to installation via clamping claws as well. The connection is even easier with the EasyLock zero-point clamping system (25mm diameter/M12). Workpiece pick-up is also particularly fast on the RVM from Röhm – thanks to the integrated quick-change system, changing the clamping jaws or rotating the jaws by 180° takes just seconds. 

"When we developed the RVM, we made sure that the overall height was designed so that the 5-axis vice could be used on as many machines of different sizes as possible making it supremely versatile. The vice really is a jack-of-all-trades that can cope with all workpieces and all geometries,” says Jörg Bauriedl, product manager for vices at Röhm.

“With the RVM, we rely on a tool-optimised design so that short-clamping tools can be used, reducing vibration significantly,” he adds. “This in turn has a positive effect on the machining accuracy of surfaces and fitting dimensions, as well as on tool life. Another advantage of the open design is that chips can flow off optimally and the vice can be easily cleaned.”

During machining, the RVM puts an end to potential error sources because, with all tasks, clamping is only done once. The workpiece is therefore stable and immovable in position from the beginning to the end of the machining process.

This is made possible by the good accessibility of the optimised interference contour combined with the high clamping force of 40kN per jaw. "This enables us to transfer the accuracy of the machine almost 1:1 to the workpiece – and this applies to small workpieces as well as large,” Mr Bauriedl explains.

In terms of handling, the RVM excels. The clamping centre can be removed, repositioned, and reattached to the base body in just a few simple steps, all thanks to a central clamping screw on the fixed jaw and the dimensional scale on the base body.

Röhm has a wide range of accessories available for the RVM such as stepped jaws, block jaws, workpiece supports, workpiece stops, as well as standard fastening material such as clamping claws, keyway nuts and clamping bolts for the zero-point clamping system.
