BEIJING GENERAL MAGNETIC TECHNOLOGY INSTITUTE
BGMT is in the lead of machining technology in the magnetic material field. We supply machining service to the manufacturers of rare earth permanent magnetic material, and mainly provide the micro motor manufacturers with the ring magnet of rare earth permanent material. We can cut the NdFeB and SmCo magnet block, grind the square magnet to the circle magnet, drill the hole in the magnet, and plate the NdFeB magnet with plating Nickel or electroless plating Nickel. Especially we have great skill in drilling small hole and thin wall hole in the NdFeB and SmCo magnet. We developed a new technology that was called ultrasonic machining technology. Using this technology we can drill the small hole and thin wall hole in the NdFeB and SmCo magnet at a high speed, and the rate of qualification is higher than the general machining. So we can machine the NdFeB and SmCo magnet in low price and high quality. Our main products is listed as follows:
Grade-------------Size**(mm)------------Application-----Price*(US$)
NdFeB N43M OD2.5*ID1.75*L4.8 Coreless motor 0.070
NdFeB N45M OD2.0*ID1.35*L4.6 Coreless motor 0.064
NdFeB N45M OD2.6*ID1.05*L5.6 Coreless motor 0.052
NdFeB N42 OD4.0*ID2.05*L5.8 Coreless motor 0.048
NdFeB N38H OD10.8*ID6.2*L1.5 CD-ROM 0.040
NdFeB N38 OD1.5*ID0.35*L0.8 Sensor 0.012
SmCo R28 OD5.0*ID3.50*L3.5 Micro motor 0.22
SmCo R28 OD4.0*ID2.05*L5.8 Coreless motor 0.20
SmCo R28 OD3.0*ID1.80*L4.0 Sensor 0.18
SmCo R28 OD2.6*ID1.70*L7.0 Coreless motor 0.24
SmCo R28 OD2.8*ID1.05*L3.4 Coreless motor 0.12
*It is the local producer¡¯s price, and the minimum amount of order is 5000pcs.
** OD-Outer Diameter, ID-Inter Diameter, L-Long or thik.
Our products mainly can be used in small coreless vibration motor, which usually is fitted on moble, BP and camera. They have two advantages, one is the narrow tolernce, and the other is the smooth surface. The precision of machining can be reached: OD¡À0.01mm, ID¡À0.02mm, L¡À0.02mm. According to the customer¡¯s demand, we also can plate the NdFeB magnet with eletroless plating Nickel. And the ability of rust-resistant of NdFeB magnet can be reached: 72 hours in the 5% salt spray.
Generally we buy the raw material from the large companies which own the permission of NdFeB patent. So if the customer want to use our NdFeB magnet, patent is not a problem. We also can process the customer¡¯s raw material. We will reduce your cost and solve your problem of drilling on the magnets.
