We produce permanent-magnetic chunks of different specifications: the intensive type, the delicately intensive type and heavy-intensive type, etc.. They are mainly made of high-performance NdFeB magnetic materials, which have excellent magnetic property, high remanence and Maximum energy. Besides, these advanced-structured chunks can be operated easily and safely. They can be applied to holding work piece of magnetic material to be ground on processing center, surface grinding machines, linear cutting machines and EDM shaping machines etc. Our permanent-magnetic cranes are also of various specifications. The heavy-duty alnicos used in the cranes guarantee the eternal, intensive and steady operation.
