Tungsten Carbide Ball Eccentric Arc Slot Grinding (1/2)

Compared with tungsten carbide ball V-slot grinding process, the rotating center of eccentric arc slot is deviated from the overall center. And the linear velocity of contacting points between tungsten carbide ball and grinding tray, it also adds a new rotary motion, which makes spin angle convert from relative invariant into the space amount, and the space included angle of axis of revolution become larger. The schematic of eccentric arc slot grinding tray is given as follow:

We can see from the figure, the eccentric circular groove grinding its way movement can be broken down into simply V-groove movement along the X axis and pure rolling. By adjusting the rotational speed, changing the relative velocity of the polishing, and it can achieve a wide range of spin angular variation, and to satisfy the carbide ball into round basic conditions that is 1. Equal probability: each dot on each of them to be processed carbide surface of the ball has the same probability of cutting; 2. Alternatives of grinding: in the process of grinding, the ball with large size should be ground more and the small size ground less or not; the margin of the longitudinal direction should be ground more and the margin of minor axis direction ground less or not.
