Methods for preparing raw magnets and cutting workpieces

Abstract

This disclosure relates to a blank magnet and a method for cutting a workpiece. The method includes: fixing the workpiece on the worktable of a multi-wire cutting machine; setting the linear speed of the cutting wire of the multi-wire cutting machine to 1500-1800 m / min, wherein the cutting wire comprises a metal wire and diamond particles coated on the metal wire, and the diameter of the cutting wire is 0.08-0.15 mm; and moving the worktable toward the cutting wire at a predetermined speed to cut the workpiece, wherein the predetermined speed is set to 0.1-0.3 mm / min. The multi-wire cutting machine offers high cutting speed and low cutting depth, resulting in less vibration during cutting and producing high-precision blank products. Therefore, products cut using diamond-coated cutting wires do not require further grinding to meet surface roughness and dimensional tolerance requirements, thus saving manpower and resources, significantly improving production efficiency, and reducing production costs.
