An electromagnetic chuck is a device used in machining processes to hold ferromagnetic workpieces securely in place. It operates by generating a magnetic field when electrical current flows through coils within the chuck, allowing it to grip metal parts without the need for mechanical clamps. This feature enhances precision and efficiency during operations like milling and grinding. These chucks are commonly used in CNC (Computer Numerical Control) machines, where accurate positioning is crucial. They can be easily activated or deactivated, enabling quick loading and unloading of workpieces. This versatility makes electromagnetic chucks popular in various manufacturing industries.
