Vibratory Tumblers

Silicon Carbide Abrasives

These abrasives have sharp, hard grains for fast cutting. Use in tumblers, flat laps, sphere machines or wherever coarse and fine grinding grits are needed. The grit sequences below are standard, but can be varied depending on material and need. Standard sequence for rotary tumblers is 60/90, 220 and 600 silicon carbide, followed by a polish. For best results, use an aluminum oxide pre-polish 800 grit before the final polish. Use this same silicon carbide sequence including the aluminum oxide pre-polish, in vibratory tumblers. When lapping, add the 400 and 1000 grits to the standard sequence.

Grit sizes actually indicate a range in particle size, so that a sample of 220 grit, for example, may have particles ranging from 100 to 300 in size. The more a grit sample is graded or processed, the more particles are similar in size, and the more expensive the sample becomes. This is the reason that the coarser grits are cheaper than highly refined polishes.

Grits are packages in sturdy containers for convenient storage and use, which also prevents leakage and contamination.
