Normal Pitch Permanent Magnetic Chuck: Application: 1. Suitable for heavy and light grinding. 2. Can be used in discharging-process machine,carving machine and CNC. Feature: 1. While turning magnetic force ON/OFF, the flat faceaccuracy of magnetic force surface does notchangeand can keep high precision processing surface. 2. The fine-pitched magnetic poles make it ideally suitablefor small and thin work pieces. 3. Made from permanent magnet,with strong suction andless remained magnetism. 4. Specially designed for steady and high precision operation.
