Neodymium sphere magnet, also known as the buckyball and magnetic ball, is ball shaped magnet which commonly used as consumer products, stress-relief products, educational toys, or an artistic medium. Neodymium sphere magnets were first introduced to the customer market as buckyball at the New York International Gift Fair in 2009. The polarity configuration of Neodymium sphere magnet is similar with earth. Neodymium sphere magnets are available in a wide range of diameters, grades, and colors, then SDM have got millions of products in stock. We must warn customers that small neodymium magnet toys can cause severe damage to the digestive system and bowel if swallowed by children.
Manufacturing and Surface Treatment of Neodymium Sphere Magnet
Machining process of Neodymium sphere magnets has been less concerned by users in comparison with colors and creative shapes. Sintered Neodymium magnet is considerable hard and brittle, then cannot be processed by forging technology like frequently used steel ball bearings. In reality, machining process of ball magnet is mainly fulfilled by copy grinding process. Copy grinding process normally select Neodymium cylinder magnet with suitable size as raw material in view of dimensional precision, processing efficiency, and material utilization ratio. In addition to conventional metallic coating like Nickel, different coloured paints apply to the buckyball magnet via spraying process.
