Wheel Dressers and Dressing Tools Information - GlobalSpec

Wheel dressers and dressing tools are used to condition, true, and dress grinding wheels. Dressing is the process of re-sharpening the tiny cutting edges on a grinding wheel’s surface. Diamond tools and wheel dressers fracture the grinding wheel’s abrasive grains in order to produce sharp new edges.

The Properties and Uses of Silicon Metal

Silicon metal is a grey and lustrous semi-conductive metal that is used to manufacture steel, solar cells, and microchips. Silicon is the second most abundant element in the earth''s crust (behind only oxygen) and the eighth-most common element in the universe. Nearly 30 percent of the weight of the earth''s crust can be attributed to silicon.

Silicon - Wikipedia

Silicon compounds such as silicon carbide are used as abrasives and components of high-strength ceramics. Silicon is the basis of the widely used synthetic polymers called silicones. Elemental silicon also has a large impact on the modern world economy.

Silicon Carbide - an overview | ScienceDirect Topics

Silicon carbide wears more rapidly when used to grind metals that have an affinity for carbon such as iron and nickel. It is therefore used primarily for non-ferrous materials. Green silicon carbide (Figure 3.2(a)) is higher purity than black silicon carbide. Green silicon carbide is sharp and friable which makes it a good abrasive.
