A method for manufacturing a clamp assembly and an outer cutter cutting wheel

One kind of outer blade cutting wheel comprising a cemented carbide substrate and a thin annular blade portion in the form of a disc, which is manufactured by the following method: the permanent magnet is arranged on the side surface of the sheet and a position within the circumferential surface of the base to form a magnetic field , the magnet is coated onto the diamond and / or CBN abrasive particles to a magnetic field capable of acting on the particles, causing the particles to be magnetically attracted to the outer peripheral surface of the substrate, and plating or electroless plating, whereby the abrasive particles are bonded to the base body an outer circumferential surface of the blade portion to form.
