Workpiece Clamping Magnets for Milling on CNC Machining Centers and Milling Machines

Introduction and Primary Use

Workpiece clamping magnets, also known as electro-permanent magnetic chucks, are essential tools for milling operations on CNC machining centers and milling machines. These magnets are designed to securely hold workpieces during the milling process, ensuring stability and precision. They are mainly used for operations such as milling, blind and through-hole drilling, flattening, contouring, pocket milling, and shaping profiles on workpieces of various sizes and thicknesses.

Functioning

Electro-permanent magnetic chucks use high-power Alnico and Neodymium magnets embedded within their structures. These magnets generate attraction forces up to 1100 kN/m², ensuring the workpiece remains firmly in place during machining. The chucks are made of C45 steel, with a thickness of 66 mm, machined from solid to resist deformation and stress. The magnets are activated and deactivated via an electronic control unit, allowing precise and safe operation.

Fields of Application

Workpiece clamping magnets are used in a wide range of industrial sectors, including:

• Automotive Industry: For the production of high-precision automotive components.
• Aerospace: For complex machining on advanced materials.
• Tool Manufacturing: For creating high-precision tools.
• General Mechanics: For machining various mechanical components.

Fixed and Movable Pole Extensions

Pole extensions, both fixed and movable, are fundamental accessories for magnetic chucks. Fixed pole extensions ensure precise positioning of the workpieces, while movable pole extensions allow for automatic shimming, improving flatness tolerances. These accessories extend the usage and application possibilities of magnetic chucks, making them more versatile and adaptable to different working needs. When used correctly, pole extensions better withstand the machining stresses generated by the machine tool. Roehm, in collaboration with Tadaah, can also recommend or create customized chucks or pole extensions, offering the right solution for clamping shaped, round, and profiled workpieces.

Electronic Control Unit and Its Importance

Purchasing the electronic control unit is essential for the optimal operation of magnetic chucks. The single-channel control units can individually operate multiple magnetic chucks and are equipped with a military-grade IP67 sealed connector for quick magnetic chuck connection/disconnection. The control unit ensures precise control of magnet activation and deactivation, enhancing operational safety and efficiency.
