6x12 Inch Rectangular Magnetic Chuck (150x300mm), 100-120 N/cm² Strong Holding Force for Surface Grinder, Milling Machine & EDM Workholding

6x12 Inch Rectangular Magnetic Chuck (150x300mm), 100-120 N/cm² Strong Holding Force for Surface Grinder, Milling Machine & EDM Workholding

• High-Density Fine Pole Magnetic Design: Constructed with high-performance N42-N45 grade magnetic steel, this chuck delivers a powerful and uniform holding force of 100-120 N/cm². The precision fine pole spacing ensures even magnetic distribution, allowing it to securely hold not only large workpieces but also thin and small parts, preventing deformation or shifting during machining.
• Zero Electricity & Easy Operation: No power source or cables are required. Simply rotate the shaft hole 180° using the included wrench to instantly switch the magnetic force on or off. This purely mechanical design simplifies the workflow, eliminates the risk of power failure, and ensures operational safety.
• Precision Ground Surface & High Flatness: The working surface is finely ground on all six sides to ensure exceptional flatness and parallelism. The surface precision remains stable even after repeated on/off switching, eliminating the need for constant re-truing and providing a reliable foundation for precision grinding tasks.
• Durable Construction with Protective Seal: The magnetic plate features a special sealing treatment to provide excellent leak-proof protection. This effectively shields the interior from corrosion by cutting fluids and coolants, extending the service life of the chuck and ensuring reliable performance in demanding workshop environments.
• Wide Application Compatibility: This permanent magnetic chuck is an ideal workholding solution for surface grinders, tool grinders, milling machines, and EDM machines. Its strong adaptability makes it a valuable tool for precision positioning and clamping in metalworking, mold manufacturing, and various general machining applications.
