Abstract: According to the demand of NdFeB magnetic material processing in 3C consumer electronics industry, a multi-wire cutting machine is designed and manufactured, which can process NdFeB magnetic material into thin sheets with thickness less than 1mm. In this paper, the precision requirements of NdFeB magnetic material processing by multi-wire cutting machine are introduced, as well as the overall design scheme of the multi-wire cutting machine. The structure and function of the key components, including feed components, roller components and wiring components, are introduced. The working principle of the whole machine and the advantages of the multi-wire cutting machine are introduced, which provides a reference for the machine tool design in the field of NdFeB magnetic material slicing.
