Application of brown corundum in the field of cutting and grinding wheels
The application of brown corundum in the field of cutting and grinding wheels is mainly reflected in the following aspects:
I. Core performance advantages
Material characteristics
Brown corundum cutting and grinding wheels use brown corundum as the main raw material, with a hardness of up to Mohs 9.0, and sharp particles that can quickly hit the surface of the material to achieve efficient cutting. Compared with materials such as silicon carbide and white corundum, brown corundum has both high toughness and high temperature resistance (melting point 2250℃), which is suitable for high-intensity processing scenarios.
Economical and environmentally friendly
Low loss: 24 mesh, 30 mesh, and 36 mesh brown corundum can produce 11 million effective particle impacts per kilogram, and the loss is only 1/3 of conventional abrasives.
Recycling: Brown corundum can be reused 5-10 times, and can be reused as cement additives after failure.
Non-toxic and environmentally friendly: Brown corundum does not contain harmful substances such as free silicon and heavy metals, avoiding the risk of silicosis.
2. Applicable material fields
Metal materials
Applicable to the cutting of metals such as stainless steel, alloy steel, copper, and aluminum. It can efficiently remove the oxide layer and keep the cutting surface flat.
Non-metal materials
Widely used in the cutting of hard materials such as stone (such as marble, granite), ceramics, glass, and concrete, with both speed and precision.
Special process scenarios
In hydraulic cutting, brown corundum is combined with high-pressure water to achieve environmentally friendly and safe cutting effects, replacing garnet water jet sand in some fields.
3. Extended application scenarios
Brown corundum cutting and grinding wheels are also used to manufacture tools such as grinding wheels and grinding heads, which are suitable for high-precision processing requirements such as aerospace and automobile manufacturing. Its high temperature resistance also supports special working conditions such as refractory material cutting.
