The use of electric permanent magnetic chuck and note
Structure of electric permanent magnetism
The electromagnetic chuck is made of a bottom shell, a core, a coil, a panel, and a junction box.
The production process is as follows:
1 select the appropriate material for welding or casting the bottom shell
2 the iron core is installed on the bottom shell according to the different types of sucker.
3 winding the corresponding number of turns and technical parameters of the coil, after drying the core
4, the inner shell of the internal casting asphalt or other waterproof material
5, the production panel, and the bottom shell parts are installed together
The electromagnetic sucker adopts DC power supply, with a stable, strong suction, characteristic remanence is small.

Electromagnetic sucker according to different classification can be divided into ordinary suction sucker and powerful suction. General market products ordinary suction sucker suction 10-12 kg per square cm, powerful electromagnetic chuck not less than 15 kilograms per square centimeter. According to use can be divided into electromagnetic sucker, milling planer with the electromagnetic sucker, sharpening machine electromagnetic sucker CNC machining center dedicated sucker. Lifting electromagnetic sucker for grinding machine and so on. Sheng Qiang energy company to exquisite processing technology with mature and stable technology to achieve the common suction sucker suction 16-20 kg / cm2, the powerful electromagnetic chuck in 54-60 kg / cm2, magnetic force is far more than the general market products.

Purpose and characteristics
The magnetic work table of the rectangular electromagnetic chuck is a surface grinding machine or a milling machine, which can absorb all kinds of magnetic field and realize the positioning and grinding of the workpiece. The suction suction is uniform, reliable and easy to operate. It can be directly mounted on a surface grinder or a milling machine.

Instructions
Electromagnetic sucking disc on both sides of the lifting screw, installation screw rings can be lifting, with T shaped block and screw fixed on the workbench, switch on the machine on the DC power supply and the ground, then sucker flat grinding time and to ensure plane on the bottom surface of the parallelism.
In the adsorption of the workpiece, as long as the adjacent two pole, you can get enough of the suction suction, you can carry out the grinding process.
Through the machine button, the workpiece can be achieved through magnetization and demagnetization.

Maintenance and safety tips
Sucker without serious bump, so as not to damage the accuracy, when not in use, should be clean, antirust oil.
Sucker shell should be grounded, so as to avoid leakage.
Standard 10577-2006:JB/T electromagnetic chuck for electromagnetic sucker.

Safety operation technology of electromagnetic chuck
1, pay attention to the balance, should be placed above the center of the electromagnetic sucker products, and electricity, prevent light iron splash.
2, lifting, working current should reach the rated value to start.
3, landing electromagnetic sucker, should pay attention to the circumstances, to prevent the injury.
In 4, when lifting, must pay attention to between metal products and electromagnetic sucker should not be non-magnetic items. Such as wood, sand etc.. Otherwise it will affect the lifting capacity.
5, to carefully check the parts of the parts, found that the damage should be replaced in time.
6, the lifting process, to pay special attention to security, not on the equipment or personnel through the head.
