Research Status of Tungsten Sphere Grinding

Tungsten spheres are very important to us in our industrial and daily life and they are widely used in many fields. So how are tungsten spheres ground and what are the conditions to be met? Let's take a look.

Study of tungsten sphere grinding conditions

The ideal tungsten sphere has a positive circle of any cross-section, which is the basic starting point for the design of the sphere grinding method. The grinding process requires that the trajectory of the contact point between the grinding apparatus and the sphere billet (i.e., the grinding trace) is uniformly distributed on the surface of the sphere, and the amount of material removed varies with the size of the spherical deviation.

The basic conditions for grinding tungsten spheres into balls are summarized in two points: (1) Cutting equiprobability: each machined tungsten sphere has the same cutting probability at each point of the spherical surface.

(2) Size selectivity: during processing, whether the tungsten sphere is ground into a large ball, not ground or less ground into a small ball, ground in the long-axis direction, not ground or less ground in the short-axis direction is required to be selected. After these two points are reached, the tungsten ball can be ground to the desired size.

Study of the spherical grinding trajectory of tungsten spheres

The distribution of the grinding trajectory of the tungsten spherical surface is one of the important influencing factors for the formation of the spherical surface during the grinding process. Since the grinding process creates a large force when the grinding edge cuts into the surface of the tungsten sphere at a very high speed, if the conventional grinding method is used, it will easily lead to uneven spherical grinding trajectories, making the produced tungsten ball not smooth enough or even not meeting the requirements. The active angle control grinding method can improve this to a large extent, by controlling the grinding angle to control the amount of cut-in, the shallow cut-in will not produce excessive grinding depth and will not produce too much force to make the spherical grinding trajectory change.

Only the smoother the tungsten sphere surface is ground, the more suitable it is for processing into some key components that need smooth tungsten balls, such as tungsten ball bearings.

Study of tungsten sphere grinding process

It is found that the design of the grinding groove and the material properties of different grinding discs will affect the sphericity and surface smoothness of the tungsten spheres, which simply means that it will affect whether the tungsten spheres will end up smooth and rounded like a sphere or not. The stiffness of the grinding disc and the processing load will affect the movement of the tungsten balls during the grinding process as well as the interaction forces, which will affect whether the tungsten balls will be deformed excessively during the grinding process, resulting in inferior products.
