This work use the SPH method to study the relationship between grinding depth and grinding force of K9 glass in ultra-precision grinding, and the effect of grain shape on material removal. The relationship between the force and the depth in the stable scratching stage is FR = 0.55078ap1.15356, which provides a basis for controlling the grinding depth by force. The …

Fine Art of Making Spheres. Making of spheres is not difficult but it takes large rocks and much time, usually from 24 hours to 50 hours of sawing on large rock saws and grinding and polishing on sphere machines. Softer material such as alabaster, onyx, and marble will cut faster and are desirable for first time sphere cutters.
It was found that mixtures of grinding media shapes can increase the breakage rate in a particular milling environment. But, spherical balls remain the most efficient grinding media. Finally, an optimal mixture made of grinding media of different shapes cheaper to

We wish to precisely describe the shape into which we will distort the sphere. We assume that at each pole (as in the north and south poles of the earth) we reduce the diameter by grinding to 2(r d) where ris the radius of the sphere and dis the depth of grinding on each of two opposite poles. Such a grinding operation would typically leave a ...
A sphere grinding machine, comprising, in combination, a table supported upon legs, a motor driven grindstone carried upon said table providing a means for grinding a surface of a stone for imparting a spherical shape thereto, a slide member with an insert-carrying stone holder carried by said table with crank means for moving said stone holder ...
They are used in the grinding phase of sphere making. These are made with inserts of 60 grit diamond silver soldered to the steel tubing ring. They are drilled on the back to accept the ABS plastic backs that use a ¾ inch pipe thread to screw onto the sphere machine. They come in 3 different sizes depending on the size of sphere you want to grind.
