The XM91 Rectangular Permanent Magnetic Chuck is engineered for high-precision machining applications. Designed to provide uniform and strong magnetic force, this chuck is ideal for surface grinders, wire cutting machines, and EDM equipment. Its advanced magnetic pole layout and high-performance materials ensure stable clamping of thin and small workpieces, such as steel and aluminum alloys, without the need for external power.

• Key Features

High-Density Magnetic Poles

• Uniform Magnetic Force: Magnetic pole intervals as fine as 1.55mm (0.5-1.5mm for some models) ensure even distribution of force, preventing deformation or displacement of thin workpieces (≤6mm thickness).
• Precision Grinding: The working surface is ground to a flatness error of ≤0.01mm, meeting IT7 tolerance standards for high-precision grinding.

Strong Adsorption and Stability

• High-Performance Materials: Utilizes neodymium iron boron (Nd-Fe-B) permanent magnets, delivering a unit suction force of over 14kg/cm²—twice that of standard chucks.
• Power-Free Operation: Relies on permanent magnets, eliminating the risk of workpiece detachment during power failures, ensuring safety and energy efficiency.

Durability and Environmental Adaptability

• Anti-Corrosion Design: Features stainless steel or plated panels with a sealed structure to resist cutting fluid leakage and corrosion, extending service life.
• Wear and High-Temperature Resistance: Constructed from alloy steel or high-strength stainless steel, suitable for long-term, continuous use in demanding environments.

Flexible Operation and Easy Maintenance

• Quick Magnetization/Demagnetization: A 180° rotation of the mechanical wrench switches between magnetization ("ON") and demagnetization ("OFF") with minimal residual magnetism.
• Low Maintenance: Requires only regular surface cleaning and anti-rust oil application to maintain accuracy.

Versatile Applications

• Compatibility: Suitable for surface grinders, wire cutting machines, and spark machines, supporting vertical or angled installations.
• Customization: Available in non-standard sizes (e.g., 150×300mm, 300×800mm) to meet specific workpiece and processing requirements.
