Uniform, well-graded diamond powder gives best results. Practically all particles are working constantly, resulting stock removal is fast, finish is superior and uniform without scratching or pitting. LAPPoorly graded diamond powder is wasteful and unreliable. Uneven cutting results from the fact that only large particles contact work, while small particles do not work. Scratched, pitted surface is the result. SOLARDiamond Lapping Compounds, particularly suited for the rapid polishing of all hard materials, are used extensively in the manufacture of precision components, tungsten carbide dies, precision gauges, optical flats and lenses etc. (Also in creating a high degree of finish for hard metal moulds, gem polishing and sapphire processing.) Only uniform well-graded diamond powders are used throughout the range of SOLAR Lapping compounds and Slurry. These powders are accurately and consistently graded by a special process to ensure individual particles of sound crystalline structure, blocky in shape with sharp, well-defined edges. The diamond particles are measured microscopically, the size being defined as the diameter of a circle having the same area as the diamond particles when viewed through a microscope. BASE MATERIAL
