AMB Units indicate when magnetic chucks are active

Editor: Eric Culp

Since the display module functions without an energy supply, it doesn’t matter if the magnetic clamping plate has electric current or not.

For the first time, Magnos magnetic chucks based on square pole technology can be equipped with an optical status display or a mechanical indicator for automated machine loading, according to Schunk.

These tools consistently inform whether the magnetic chuck is activated or not. The company said the principle of display is very simple: If the clamping plate has been activated, the status display turns to green, or the indicator pin telescopes. If deactivated, the display turns red, or the pin sinks into the plate.

Due to use of square pole plates, workpieces can be clamped quickly and machined from five sides in a single set-up. Moveable pole height extensions provide gentle set-up without deformations, the company explained. Magnos magnetic chucks are said to be suitable for milling, drilling, and flat grinding. The mono block design promotes high stability and rigidity to minimise vibrations, which improves the surface quality.

Schunk said it has also reduced the size of its Tribos SVP-4 toolholding systems. The automatic clamping device is much more-compact and lighter than its predecessor, the company noted, adding that a pump helps ensure quiet operation.

On option, the system can run on 220 V AC from the socket, or if required, operate remotely with rechargeable batteries. Clamping pressure for tool changes can be continuously adjusted via a controller. Mounting is said to be quick, exact and automatically actuated at the defined pressure. Maintenance and service intervals can be individually defined, the company said.
