Cutting Wheel

Cutting wheels are core cutting tools in the fields of metal processing, building demolition, etc. Their classification system is mainly based on the base material, abrasive type and cutting object characteristics. Compared with ordinary grinding wheels, cutting wheels generally adopt fiber-reinforced structure, and the thickness is reduced by 30%-50% to achieve higher cutting efficiency while maintaining sufficient bending strength.

According to the base material, it can be divided into two major systems: resin cutting blades and diamond cutting blades. Resin cutting blades use glass fiber mesh as the skeleton and are filled with alumina or silicon carbide abrasives. They are suitable for cutting metal materials such as carbon steel and stainless steel. The conventional specifications are 100-400mm in outer diameter and the speed needs to match 8000-14000 rpm equipment. Diamond cutting blades use metal matrix sintered diamond abrasives and are specially used for hard and brittle materials such as concrete and stone. The width of the blade is usually controlled at 2.5-3.5mm to reduce material loss.

In terms of structural innovation, ultra-thin cutting blades (thickness 1.0-1.6mm) are widely used in the field of precision machining, and the cutting accuracy can reach ±0.05mm when combined with laser welding technology. The explosion-proof cutting disc is reinforced with a double-layer fiber mesh, which can maintain structural integrity under the overload condition of the angle grinder. In recent years, composite cutting discs have become popular, such as the mixed abrasive design of nickel-plated diamond and zirconia corundum, which enables a single tool to cut both steel bars and concrete.

Special application scenarios give rise to special products: the use of aluminum alloy matrix cutting discs with heat dissipation holes in the automotive repair field can reduce the cutting temperature by 40%; the semiconductor industry uses nano-diamond coated cutting discs, which are combined with deionized water cooling to achieve non-damage wafer cutting. With the tightening of environmental protection policies, the market share of cobalt-free metal binder cutting discs has increased to 35%, while maintaining cutting efficiency while eliminating the risk of heavy metal pollution.
