Röhm has developed its COE face drivers to allow components to be completely machined, including milling, turning and cross-hole drilling in a single set-up. The surface quality achieved is said to be similar to a milling process when the part is clamped by a vice.

Version 2.0 of Schunk's manual Rota-S Plus lathe chuck incorporates an optimised wedge bar drive system and an improved lubrication system to ensure consistently high clamping forces. Since higher rotational speeds and cutting speeds are possible, suggests Schunk, users can apply more efficient cutting strategies that reduce manufacturing time.

Roemheld's M-TECS magnetic clamping system is designed specifically for horizontal and vertical die casting machines. Because the system is stable up to 230°C, it largely covers the whole temperature range that may occur in the die casting industry. Additional benefits cited by the company include no downtime for heating up or cooling down in the press, a shorter stay in the hot area with less burning, no T-slot between the heating plate and the die, and more homogeneous temperatures inside the die.

The steel version of the Rota NCL lathe chuck weighs about 35% less than conventional power chucks of the same size, says Schunk, so faster acceleration and reduced energy consumption are possible. A new type of double cylinder guidance of the base jaws ensures that the forces are evenly distributed on the chuck body.

Kitagawa is offering companies that are developing and building lathes with a spindle speed of up to 5,600 rpm the option of fitting its Eco Cylinder. The hydraulically actuated, rotary chuck cylinder typically consumes 1.5 kilowatt-hours over a daily shift, compared with 36 kilowatt-hours for a conventional cylinder, claims Kitagawa. The company calculates that the nearly 96% reduction in power equates to a saving of more than 19 kg of carbon dioxide.

Roemheld electric swing clamps work without hydraulics and require only a 24 V direct current. This makes them appropriate for applications where the use of hydraulic elements is not possible, where the clamping elements need to be controlled separately or where the clamping force must be obtained after separation from the energy supply.

Schunk has reworked its series of Tandem clamping blocks to make them part of a modular system for highly efficient workpiece clamping suitable for a multitude of machine tools. The modular clamping system is compact but can develop enormous forces in confined spaces. The improved system is extremely flexible and can be actuated pneumatically, hydraulically, via spring force or manually.

Multiple workpiece clampings minimise 4/5-axis machine downtime and facilitate setting-up. The system is highly accurate, with the Lang Quick-Point 96 system securing the 5.5 kg aluminium Tri-Top in place and the Lang Quick-Point 52 system that secures the Makro-Grip vices to each of the Tri-Top's three faces. (The integer refers to the centre distance in mm between any two adjacent clamping studs of Lang's four-stud clamping system.)
