Overview of Magnetic Chuck ตัวเลือกแม่เหล็กยึดเครื่องจักร
Overview and Features of Chucks
• Very efficient since workpieces can be loaded/unloaded just by switching operation. • Automatization in machining process is realizable by inter locking the chuck with the machine tool.
Electromagnetic Chuck
• Attraction is electrically controllable. • Easy to make larger type of chuck.
• Constructed to reduce heat generated during power on by water cooling. • Used for high pre cision operations and exhibits features of electromagnetic chucks effectively. • Most suitable for dry grinding. (Heat from workpieces is absorbed also.) • Very efficient since workpieces can be loaded/unloaded just by switching operation. • Energy-saving, since electric power is used only momen-tarily for loading/unloading workpieces. • Energy-saving type, requiring no power source. No fear of power failure and can hold workpieces for a long time. • No heat generated and thus no thermal distortion due to temperature rise. • Uniform magnetic force irrespective of chuck sizes. • High accuracy due to no change with time passage. • Never any trouble due to suspension of power supply. • Magnetic chuck equipped with sine bar for high precision grinding and inspection. • Precisely finished to overall accuracy of 0.005 mm or better. • Various types are available from electromagnetic, water-cooling electromagnetic, permanent magnetic and permanent electromagnetic chucks.
