Innovative Magnetic Workholding for Precision Grinding #
Electro-permanent magnetic chucks are engineered to deliver reliable, high-precision workholding for surface grinding and related applications. These systems combine robust magnetic force with energy efficiency and operational safety, making them ideal for demanding manufacturing environments.
Key Features of Electro-Permanent Magnetic Chucks #
- No Continuous Power Required: Once magnetized, the chuck maintains its holding force without ongoing electrical supply, eliminating heat generation that could affect workpiece accuracy.
- Energy Efficiency: Power is only used during magnetization and demagnetization, significantly reducing energy consumption.
- Stable and Eco-Friendly Construction: The resin-bonded face plate minimizes environmental impact while ensuring structural integrity.
- Residual Magnetism Prevention: The reverse demagnetization design, along with an optional air blow system, facilitates easy workpiece removal and prevents unwanted residual magnetism.
- Durable and Waterproof: Multi-layer waterproofing and a dense structural design provide excellent chuck strength and resistance to coolant ingress.
- Versatile Pole Pitch Options: Multiple magnetic pole pitches are available, accommodating a wide range of workpiece sizes and shapes. Chucks can be combined for use on large or gantry-type surface grinders.
- Customizable Solutions: Standard and custom sizes are offered to meet specific user requirements, optimizing cost performance.
Controller Capabilities #
- LCD Display: Real-time controller and chuck status are clearly shown for user convenience.
- Remote Operation: Compatible with a cable control box for flexible operation.
- Certified Safety: Equipped with a UL-certified European standard power terminal block, supporting up to 500V/32A for safe and reliable use.
- Integrated Control: Magnetization, demagnetization, and magnetic force adjustment can be managed directly from the machine’s main operation panel.
- Adjustable Magnetic Force: Up to 16-segment magnetic force adjustment (8-segment via cable control box) allows precise tuning for different grinding operations and workpiece conditions.
