What precautions must be taken when using electromagnetic suction cups?

Electromagnetic suction cups are designed and manufactured using the magnetic effect principle of electromagnets, which have the advantages of simple operation, convenient loading and unloading, and a wide range of use. When using, the following points must be noted:

1. It is necessary to carefully remove burrs, dirt, and grinding debris from the electromagnetic suction cup and the positioning surface of the workpiece, otherwise the workpiece cannot tightly adhere to the electromagnetic suction cup. Therefore, the ground surface and the positioning surface are not parallel, and in severe cases, the workpiece cannot even be firmly sucked.

2. The material of the workpiece must be a magnetic substance, such as steel, cast iron, etc. Nonmagnetic substances (such as steel, aluminum, etc.) cannot be absorbed and cannot be directly clamped with electromagnetic suction cups.

3. In order to install firmly, the workpiece should span more than two magnetic strips on the magnetic platform.

4. For workpieces with large heights or small positioning surfaces, a sufficient number of blocking iron must be used to fix them before grinding, in order to avoid accidents caused by unstable workpieces. The height of the blocking iron should be greater than half of the thickness of the workpiece, or slightly lower than the workpiece.

After grinding the workpiece, the coolant on the electromagnetic suction cup should be immediately wiped clean to prevent the coolant from flowing into the electromagnetic suction cup and damaging the coil.
