A magnetic chuck is a tool used in machining to hold metal workpieces securely in place during processes like milling or grinding. It uses magnetic force to grip the workpiece, allowing for precise and stable operations. This type of chuck is especially useful for flat or thin materials, as it provides a strong hold without the need for clamps or fixtures. These chucks come in various sizes and designs, including permanent magnets and electromagnetic options. They are commonly found in workshops and manufacturing facilities, enhancing efficiency and accuracy in metalworking tasks. Magnetic chucks are valued for their ease of use and quick setup.
