Tungsten Carbide Ball Grinding Mechanism

Tungsten carbide ball grinding diagram below, which shows that the processing is between two cast iron lapping plates. And there is V-shaped groove on the under plate, which the groove angle is generally 60°or 90°. The material of rotation plate is the same, and the next turn plate rotation drive tungsten carbide ball trenches friction and rotational torque in the rotation and orbital motion testimony. Tungsten carbide ball contacts the groove of the grinding plate with three-point or three-line, which contact with the rotating plate driven ball as to be parallel to the axis of rotation of the grinding plate motion.

Due to the differences of line speed and the contact pressure, the contact points with the groove (line) to drive the ball as perpendicular to the axis of rotation of the grinding plate motion. The size of the spin angular groove angle is related to the shape, the angle of the groove and the rotating speed of grinding plate, which directly affects the efficiency and the machining accuracy of tungsten carbide ball grinding.
