Tungsten Carbide Ball V-slot Grinding (2/2)

Tungsten carbide ball V-slot grinding process has many advantages, such as even the vertical axis of nylon and other polymer materials can fully absorb drive vibration damping, thereby eliminating the impact of the grinding process; there is also a spacer ring in the periphery, so as to ensure the ball does not collide with each other, making the whole more orderly movement; since only the lower disc exercise pressure on the disc relative movement does not occur, a static pressure, more stable, and more conducive to the pressure adaption; the grinding area is relatively closed so that it is beneficial for grinding fluid mixing fully, which tungsten carbide balls are covered by grinding compound completely throughout the rotation and remarkably increasing the efficiency of grinding; the rotating speed is adjustable, the grinding compound can realize spontaneous circulation and the structure of grinding tray is simple to be replaced. It also can be manufactured according to different specifications, which greatly shorten grinding time and improve the precision of tungsten carbide ball.

In addition, tungsten carbide ball and the grinding disc have heightened modulus of elasticity and rigidity is good, can be considered ideal for the rigid contacts between the two, and has no deformation. Tungsten carbide ball isolation ring did not space, nor can contact between the interactions between the spheres also be negligible. In order to facilitate analysis of the physical movement of the ball along the direction of the contact surface made of pure rolling motion that the ball is in line with the abrasive disk at equal speed of the contact. Establish the A, B, C three contact points based on the mathematical model equations to calculate the spin angle θ, and the value of the spin angle θ depends on the diameter of the ball blank and the grinding disc guide groove, regardless of the grinding disc speed, general only in the case of near 0° values were basically does not change during processing. However, during processing of the workpiece and the grinding disc slide will change the value of θ, this change is a disorderly and uncontrollable factor.
