Resin-bonded CBN grinding wheels are grinding tools made with cubic boron nitride (CBN) as the abrasive material and a resin binder. They are specifically designed for the precision machining of ferrous metals and high-hardness materials (such as hardened steel, alloy steel, and heat-resistant steel), covering fields such as automotive parts, bearings, molds, and aerospace. Their processing efficiency and surface quality are significantly superior to traditional grinding wheels, and they are compatible with high-speed CNC grinding machines for automated production.
The structure of these grinding wheels includes a working layer (containing the abrasive), a transition layer, and a base. They are classified into four types based on the binder: electroplated, sintered, resin, and ceramic. Electroplated types are suitable for small-batch processing of complex shapes, resin types are used for tool and glass processing, and ceramic types, due to their trimmability and high-temperature resistance, have become the mainstream for high-speed, high-precision machining. CBN grinding wheels have a hardness second only to diamond, a heat resistance of 1250-1350℃, and strong thermal conductivity, which reduces workpiece thermal deformation. Their chemical inertness prevents them from reacting easily when processing ferrous metals, but alkaline coolants should be avoided.

More and more people are choosing CBN grinding wheels, primarily due to their advantages such as high temperature resistance, strong chemical inertness, high durability, and outstanding processing precision and efficiency, which meet the demands of fine grinding. They offer excellent cost-effectiveness and value for money; although the unit price of CBN grinding wheels may be higher than ordinary grinding wheels, their long lifespan and low wear characteristics result in lower overall costs.
Diverse products meet different needs: CBN grinding wheels can be divided into four categories based on the binder and process, suitable for different processing scenarios:
Electroplated CBN grinding wheels: Simple process, low cost, suitable for small-batch processing or grinding of complex geometric shapes, but cannot be trued;
Sintered CBN grinding wheels: High hardness and density, commonly used for mass processing of superhard materials, but at a higher cost;
Resin-bonded CBN grinding wheels: Flexible molding, low cost, suitable for small-batch processing of various shapes (such as tool regrinding);
Ceramic-bonded CBN grinding wheels: Offering the best overall performance, they are the preferred tool for high-speed, high-efficiency, and high-precision grinding.
In summary, CBN grinding wheels, with their material properties, processing advantages, and cost-effectiveness, have become a core tool replacing traditional grinding wheels in the field of precision manufacturing. Their continuously growing market share is a result of the combined effects of technological progress and market demand.
