1. Peripheral Speed

The life of the wheel, stock removal rate, and surface roughness highly depends on peripheral speed. The operator should therefore choose the optimum peripheral speed. As Soon Yang Vitrified Diamond wheels are the wet type, the recommended peripheral speed is 1500-2500m/minute, depending on the ground material(EX. 1030-1300 for PCD).

2. Infeed

Infeed is one of many important factors to determine grinding efficiency. Excessive infeed can result in shorter life span of the wheel. The optimum depth of the cut is under 1/3 of the mesh size.

Grit size Diamond Grinding Wheel
#230 or finer
Depth of Cut
0.01mm or less

3. Macine with enough Power

The super vitrified diamond wheels are designed to be used with water for both lubricatin and cooling rather than a mineral oil based fluid. By running the miscible oil type cutting fluid of between 3 and 5% by volume on the wheel, the efficiency of the wheel can be significantly improved. The use of water and the lubricant minimize the problems of waste disposal and the need to comply with a local environmental legislation.

4. Truing and Dressing

Generally, truing is necessary when trembling is found and is followed by dressing to get a good stock removal rate. However, the Soon Yang Vitrified Diamond grinding wheel, truing is almost unnecessary, since the high pore rate itself keeps the wheel loading effect very low and reduces occurrence of heat during grinding procedure.

5. GC Stone Mesh for Truing

It is recommended to use two coarser sizes than the diamond particle size to finish truing within a short time.

6. Size GC Stone for Dressing

It is recommended to use a mesh that is two steps finer than the diamond mesh to protrude diamond particle in the wheels.

7. Surface Finish

Two separate cyles are recommended in order to achieve a high rate of stock removal and a good surface finish. The fine mesh should be used after the rough mesh.
