Electro-permanent magnetic chuck Grindmaster

permanent magnetrectangularfor grinding

The Grindmaster electro-permanent magnetic chuck is designed for surface and precision grinding of a very wide range of workpieces, from very small and thin parts to larger pieces. Electro-permanent technology provides high clamping accuracy, safety (workpieces remain held by permanent magnets in case of power failure) and low operating costs.

Advantages:

• High clamping accuracy (cold magnetic system with permanent magnets)
• Minimal operating costs — only a short electrical pulse to switch on/off
• High operational safety: workpiece remains fixed by permanent magnets in case of power failure
• High and uniform holding force across the active surface
• The chuck and the workpiece can be fully demagnetized
• Several pole pitch variants available to suit different workpieces
• Alternating North/South pole layout
• STD input voltage 340 VDC (other voltages available on request)

Detailed description:
The Grindmaster series offers high accuracy and economical operation for grinding applications. A short electrical pulse activates the chuck; electro-permanent technology prevents gradual heating after switch-on, ensuring stable performance and low operating costs. The chuck delivers up to 120 N/cm² holding force evenly distributed over its surface and is available in several pole pitch variants.
