Electromagnetic suction is a kind of machine tool accessories produced by using the principle of electromagnetic conduction, through electric energy to make the internal coil electrified to generate magnetic force, through the permeability control panel, the workpiece in contact with the surface of the medium panel is tightly sucked, through the coil power off, the magnetic force disappears to achieve demagnetization, and remove the principle of the workpiece. The electromagnetic sucker is an electromagnetic fixture, which fixes the workpiece to be processed by the suction generated by the sucker body after the electromagnetic coil is energized.

 

Permanent magnet electric control disk, can provide special customization, permanent magnet electric control power disk, is a new type of permanent magnet electric control disk power disk produced by our company, easy to use, strong suction.

 

The electric permanent magnet chuck is suitable for large vertical lathe, CNC integrated machine tool, CNC milling machine tool, CNC grinding machine tool, CNC milling machine tool, CNC vertical lathe, etc. The electric permanent magnet chuck is designed with radioactive pole structure.

 

Advantages of electromagnetic chuck:
1. Suction of suction cup
Electrically controlled strong suction cup holding power, up to 16kg/cm, uniform magnetic distribution, adjustable, can be applied to a variety of strong machining, rough machining, finishing; The suction force of ordinary strong suction cups is weak and unevenly distributed, and can not withstand the requirements of strong machining operations.

 

2. Working efficiency
The use of ordinary strong suction cups requires a lot of workpiece adjustment time, which can account for 40%-50% of the entire processing process, and the clamping positioning is prone to obvious errors, high scrap rate, and very low efficiency; Electronically controlled strong suction cup with automatic auxiliary positioning function, simple press a button, 0.3 seconds to complete the workpiece clamping or release, can greatly improve production efficiency.

The electromagnetic sucker is composed of iron core, coil, panel and bracket. The electromagnet composed of a coil and an iron core is the main part of the electromagnetic sucker. The electromagnetic chuck is different due to the difference in design method or the use of materials, and is also constantly developing and improving. The electromagnetic chuck was originally used on the grinder instead of splints and bolts to fix the workpiece being ground, such a magnetic chuck is relatively simple, can only fix the plate type workpiece.

 

3. Performance
Electrically controlled strong suction cup can be used continuously, even if the continuous work for more than 20 hours a day, there will be no fault, and there is no need to do any maintenance; Ordinary suction permanent magnet in the use of about half a year will appear suction decline, and the use of electromagnetic suction cups can only work for a few hours a day, and the equipment is easy to work, the need for frequent replacement, maintenance of internal components.

4, processing accuracy
The holding force of the electrically controlled strong suction cup does not need to be maintained by connecting the power supply, and the continuous operation does not generate heat to avoid the heat deformation of the workpiece, while the strong and uniform disk suction ensures the highest processing accuracy even if the workpiece exceeds the table. The ordinary electromagnetic chuck magnetic force needs a constant supply of current, and the operation for a period of time to generate heat, not only the workpiece is heated and deformed, but also the magnetic force of the chuck decreases, and the processing accuracy cannot be guaranteed.

 

This is the traditional electromagnetic sucker, and its application has great limitations. With the development of industry, the demand for electromagnetic tools is growing, and the requirements are getting higher and higher, prompting people to make a series of improvements to the electromagnetic chuck to meet the needs of production.

 

Advantages of electric permanent magnet chuck
1, the magnetic force is strong, the magnetic force increases with the increase of the outer diameter, the processing accuracy is high, is more than 2 times of the ordinary disk, to ensure that the workpiece clamping firmly will not be scratched and strained, because the processing process does not need power supply, so the product does not exist thermal deformation phenomenon, effectively ensure the processing accuracy.

2, safe, strong, energy saving, environmental protection. The electric permanent magnet powerful disk does not need electrical energy during the working process, and only relies on the permanent magnet suction to hold the workpiece, avoiding the danger of the workpiece falling off due to the magnetic force loss of the electrical system in the sudden power failure and off-line damage. Because the electric permanent magnet sucker only uses electricity within 1-3 seconds in the process of magnetization and demagnetization, does not use any energy in the work, has high safety performance, strong and efficient force, which is both economic and environmental protection.

 

3, permanent magnet electric control disk becomes a permanent magnet after instantaneous power can absorb the workpiece for positioning and processing, after applying reverse current, you can demagnetize the workpiece safety and energy saving, easy to operate, no deformation, high processing accuracy. The product is equipped with a special charge demagnetization controller.
