Abstract
PURPOSE: To improve a resin holding power and cutting force by a method wherein a needlelike diamond particle coated with magnetic materials and a resin bond are dropped into a die held in DC magnetic field to cause a longitudinal direction of the diamond to be coincided with a direction of magnetic force.
CONSTITUTION: The needlelike diamond particle 5 is coated with a magnetic material such as nickel etc. to make a magnetized product, then the product is mixed with some resin powders and dropped into the nonmagnetic die 1 placed within DC magnetic field 4. Thus, the magnetic force 4 is acted upon the magnetic material to enable the needlelike diamond particle 5 to be coincided with a direction of the magnetic force line. For example, in a preferred embodiment, the mixture material 3 is formed by a hot press into the die 1 across an electric current of an electromagnetic coil 2 after filling of the mixture material. In this way, a longitudinal axis of the needlelike diamond particle is set to a right angle against a ground material, and thereby a resin holding power is substantially increased and almost of all the diamond particles can be effectively applied to improve a cutting force or power.
