Overview Of Electromagnetic Chuck Technology

Electromagnetic chuck working based on electromagnetic principles which is a machine tool accessory. When the internal coil is energized, it generates a magnetic force that is transmitted through a magnetic conductive panel to firmly hold ferrous workpieces on its surface. Once the power is cut off, the magnetic force disappears, allowing for demagnetization and release of the workpiece. Its mechanism seems simple, but it is a complex combination of electromagnetism and materials science.

Modern electromagnetic chucks use direct current (DC) power supply, offering advantages such as high stability, strong magnetic force, and low residual magnetism. Based on magnetic force, they are classified into standard magnetic chucks (magnetic force of 10–12 kg/cm²) and high-power electromagnetic chucks (magnetic force not less than 14 kg/cm²). Depending on their applications, there are various types including chucks for grinding machines, chucks for milling and planing machines, and chucks for knife grinders.

Electromagnetic chuck is a kind of machine tool accessory equipment based on electromagnetic principle. Through the internal coil energized to generate magnetic force, and then through the conductive panel will be contacted in the panel surface of the iron workpiece tightly adsorption, power failure after the disappearance of the magnetic force to achieve demagnetization, so as to complete the workpiece fixed and release. Seems to be a simple principle behind the electromagnetic and material science is a subtle combination.
