摘要： When a rare earth magnet block is cut or ground by a cutting or grinding tool, a jig is used for holding the magnet block in place. The jig comprises a base, a pair of metal support members disposed on opposite sides of the base and provided with grooves, and rubber rods received in the support member grooves such that the rubber rod partially protrudes from the groove and abuts on the groove bottom. The magnet block is rested on the base and clamped between the rubber rods. The volume of the groove is larger than the volume of the rubber rod.
