Countersunk NdFeB permanent magnet

Details of countersunk hole NdFeB permanent magnets
Countersunk hole magnets are also called countersunk hole magnets. Counterbore powerful magnets are installed and fixed in the required position through screws. The size of the countersunk hole magnet generally uses the large D to represent the diameter, d1 represents the diameter of the countersunk hole, d2 represents the inner diameter of the straight hole, and H represents the thickness (height).
Speaking of this kind of countersunk hole magnet, do you feel that it is indeed strange? So let me give you a few examples to see if you feel familiar with them. On children's toys at home, especially those robots, There are some big screws on it. Although I thought it should be easy to unscrew it, when I actually put it into practice, I found that it is very difficult to get out. It feels like there is something sucking on it. This kind of magnet is one of the round counterbore magnets. A special kind: screw hole magnets.

Our company can customize strong NdFeB countersunk hole magnets of any specification and performance, high temperature resistant countersunk hole magnets, square rectangular double countersunk hole magnets, annular countersunk hole magnets, etc. If you need magnet quotations and proofing, please send us drawings and samples.

1. The material composition of the countersunk hole magnet is made of metal praseodymium and neodymium, pure iron, and ferroboron according to a certain proportion and then added with certain metal elements through multiple processes.
2. NdFeB is subdivided into sintered NdFeB and bonded NdFeB. Commonly known as powerful magnets or permanent magnets, sintered NdFeB magnets are because the magnetic properties of sintered NdFeB magnets are far better than those of bonded NdFeB. Iron boron.
3. Preparation process: Ingredients - Smelting - Powdering - Pressing - Sintering (sintered NdFeB) - Processing - Magnetization to make finished products. The processing process includes: grinding, slicing, wire cutting, drilling, drilling, electroplating, etc. .
4. Surface treatment of curved NdFeB magnets, common ones include galvanizing, nickel plating, nickel-copper-nickel plating, epoxy resin, electrophoresis, gold plating, etc.

Countersunk hole magnet characteristics
1. The countersunk hole magnet has strong magnetic force, long-lasting force, and strong load-bearing capacity. It can absorb and absorb items that are several times larger than its own volume.
2. The material is environmentally friendly, has stable magnetic force and strong corrosion resistance. It can generally pass the salt spray test for 96 hours.
3. Resistant to high and low temperatures, made of high-quality rare earth NdFeB, ferrite and other materials, with multiple temperature configurations available from -50°C to 260°C.

Correct separation method of magnets
1. Slide a magnet off the top of the stack.
2. Once off the stack, carefully begin lifting the magnet.
3. Suction from a long distance, please be careful of the magnet breaking and pinching your hands.
