QHMAG electro permanent magnet chuck cnc milling machine magnetic table

Electro Permanent magnet working principle:

The working principle of the permanent magnet fixture is to use the characteristics of different permanent magnet materials, through the electronic control system on the internal magnetic circuit distribution control and conversion, so that the system internal magnetic field to achieve their own balance, or degaussing state, or release to the fixture Surface, that is, magnetic state.

What is electro permanent magnetic chuck ? 

It is widely used in lathe, milling machine, boring machine, grinding machine,Mobile phone chuck, turnout processing etc.,  using the overall processing, the inside without moving parts, with high strength and high rigidity, can meet all kinds of  machine stroke and various types parts of high-precision processing, strong and perfect suction, the maximum  magnetic force up to 16kgf/cm2.

Compared with the traditional clamp, the permanent magnet chuck eliminates the need of screw, platen and other fixture,  the work piece is easy to install, to achieve a clamping 5-sided processing,rapid batch processing improve production  efficiency. With the use of elastic magnetic block,deformation of the work piece can easily grasp the processing, and the  adsorption force is uniform, will not make the work piece stress deformation.

Advantage of electro permanent magnetic chuck :

1. Strong magnetic force, high precision machining

    Table maximum suction 13-16kg / cm ², is about 2 times the ordinary magnetic sucker to ensure that the workpiece fixture will not be a clear shift, due to the processing process does not require power supply, so this product does not exist thermal deformation, effectively guarantee The processing accuracy.

2. Strong security, energy saving and environmental protection

   Machining center sucker in the course of the work does not require electricity, rely on permanent magnet suction suction workpieces, to avoid the electromagnetic system in the sudden power failure and damage to the magnetic loss of the workpiece and the risk of falling off the workpiece. As the permanent magnet sucker only in the magnetization and demagnetization process within 1-2 seconds of the use of electricity, work without the use of any energy and produce safe, strong and efficient force, both economic and environmentally friendly.

      This new type of CNC machining center disk in the instant power after the permanent magnet can be hardened workpiece positioning processing, the application of reverse current, you can demolish the workpiece removed, safe and energy saving, easy to operate, no temperature rise and change, processing accuracy high.

       Strong support. In theory, the unit of permanent magnet fixture clamping force of 150KN, far greater than the cutting force, even the uneven surface of the fur, but also safe to suck, even if the milling quality of 52HRC hardened hardened workpiece, the same can normal work.

3.Save cost,no remanence cost.

  Magnetic flux leakage phenomenon. Electromagnetic permanent magnet fixture in the suction clamping process, but there is magnetic force on the surface of the fixture, the other surface does not exist magnetic flux leakage phenomenon, not only the tool without any effect, and remove the workpiece, the fixture and the workpiece will not exist remanence , Because the system has an internal electro mechanical demagnetization device, the workpiece and fixture can be automatically demagnetized.

4. Easy to use.

 The advantage of the permanent magnet fixture is that the workpiece positioning and clamping is very convenient, do not need cumbersome and strenuous manpower operation. At the same time, because the suction force is only in the bottom of the workpiece, the workpiece does not need to use the clamping plate clamping, to avoid the clamping force caused by the workpiece deformation and scratches. The permanent magnet fixture can realize the automatic adjustment of the workpiece. At the same time, it can realize the machine tool without vibration cutting, grinding, milling and so on, which can prolong the service life of the machine.

Usage : 

Electric permanent magnet fixture can be used for steel materials, cutting, grinding, milling and other processing of the clamping, switching state close to the power button, there is no magnetic field off, the suction will always have magnetic, and magnetic force does not take time Attenuation, even if the power or drag cable damage is not affected, it is known as safety fixture.
