Product Overview
Electro Permanent Magnetic Chuck (EP75 Series) is a high-performance magnetic clamping solution with 75mm*75mm standard magnetic poles, providing 15-17 kgf/cm2 clamping force. It adopts advanced electro-permanent magnetic technology, only consuming power during magnetization and demagnetization, maintaining permanent magnetic force without continuous power supply. The chuck is widely used for precision and heavy-duty machining of large metal workpieces, with strict performance testing including slippering force, waterproof, temperature rise and demagnetization tests.
