The electromagnetic chuck used by the grinder is named according to the classification of the use of the electromagnetic chuck, and the electromagnetic chuck used by the grinder can be divided into longitudinal and transverse electromagnetic chuck according to the pole arrangement.
① According to the pole density can be divided into wide pole electromagnetic chuck and dense pole electromagnetic chuck.
② According to the strength, it can be divided into general electromagnetic suckers and strong electromagnetic suckers.

Common problems and maintenance methods of grinding machine powerful electromagnetic chuck:
The suction of the strong electromagnetic sucker is not strong, resulting in the reduction of the suction of the strong electromagnetic sucker for many reasons:
1) The input voltage of the powerful electromagnetic chuck drops.
2) Due to the roughness of the panel, the self-solution: the self-grinding strong electromagnetic suction table can be repaired and adjusted.
Grinding machine powerful electromagnetic sucker test method：
The output voltage between pin 1 and pin 2 of the powerful magnetic suction demagnetizer is measured with a universal meter. The voltage is DC110V with load and DC127V with no load.
The output voltage regulation method of the powerful electromagnetic suction demagnetizer:
Rotate the component labeled 202 clockwise to increase the output voltage; The electric permanent magnet sucker rotates the component labeled 202 counterclockwise, and the output voltage increases.

How to use the grinder’s powerful electromagnetic sucker correctly
The rectangular electromagnetic chuck is provided with lifting screw holes on both sides. During installation, T-shaped screws can be lifted, fixed on the workbench with T-shaped blocks and screws, connected to the DC power supply and ground wire on the machine tool, and then the upper plane of the chuck is finely ground once to ensure the parallelism between the upper plane and the bottom surface.
When the workpiece is adsorbed, as long as the two adjacent magnetic poles are connected, enough positioning suction can be obtained to grinding.
Through the button of the machine tool, the magnetic flux and demagnetization of the workpiece can be realized. The suction cup shall not be seriously bumped, so as not to destroy the accuracy. When idle, it should be wiped and coated with anti-rust oil. The sucker shell should be grounded to avoid leakage and injury. Please pay attention to safety.
