Overview
This document provides technical specifications and applications for various types of magnetic chucks, including permanent magnetic chucks and permanent electromagnetic chucks. These tools are essential for securing workpieces during machining processes.

Permanent Magnetic Chucks

• Model RMCW (Thin and Circular Type): Suitable for a wide range of workpieces, from small to large, and thin to thick. The chucks are thin (43 mm to 60 mm) and feature a micro pole pitch, allowing them to handle various sizes of workpieces. The handle is a hexagonal wrench key, requiring only a half turn to switch the magnetic force on and off. The handle can also be set to provide a weak magnetic force for easy positioning and temporary securing of parts.
• Model SKM (Rectangular Chuck Type): Designed for applications where workpieces need to be held vertically or secured from the sides. It uses a powerful RMT rare earth magnetic chuck, capable of holding various sizes of workpieces, including thin, small, and thick items.

Specifications
The document includes detailed specifications for different models, such as dimensions, pole pitch, thickness, handle type, and mass. For example, the RMCW-50B model has dimensions of 500 mm x 500 mm, a mass of 92 kg, and uses a hexagonal handle.

Applications and Features
These chucks are versatile and can be used in various machining applications. They are particularly useful for securing workpieces temporarily and can handle a wide range of sizes and shapes. The document highlights the ease of use with the hexagonal wrench key and the ability to adjust the magnetic force for different needs.

Conclusion
The document provides comprehensive information on the specifications and applications of magnetic chucks, emphasizing their versatility and ease of use in machining processes.
