Motor Neodymium magnet is an alloy magnet made from ND, Fe, B and other trace metal elements. It is a rare earth magnet known so far for the strongest magnetism as well as high performance (8MGOe-55MGOe) and good coercive force. Proven production process, strict quality assurance, complete technical service and remarkable cost performance.
Machining and tolerances
Neodymium is easily ground, although coolants must be used in the process to avoid spontaneous combustion of powder. Grinding should be completed before coating or plating is applied to protect the magnets from corrosion. Standard tolerances for neodymium magnets are +/-0.05mm for ground dimensions.
Temperature constraints
The temperature coefficient of neodymium has triggered several grades to be developed to meet specific operating requirements. Please refer to our chart of magnetic properties to compare the characteristics of each grade. Before choosing a neodymium magnet be sure to consider your application's maximum operating temperature.
Added value services
Our knowledgeable engineering department is always available to assist in determining the best grade and size of neodymium magnet for your application. We also offer coating and plating choices for magnets we custom-machine.
Tunneling jumbos refer to rigs used for underground excavation projects such as underground mine tunnels, railway and highway tunnels, and hydraulic culverts. It can also be used for drilling bolt holes, filling method or room and pillar mining blasthole. The hole diameter is 25-64mm, and the hole depth is 1-5.5m, often 2.5-4m. It is suitable for the tunnel section of 3.2-150m2. The selection of the tunneling rig is mainly based on the roadway section and the driving speed, and at the same time, factors such as the turning radius of the roadway and the support method must be considered.
