What is a CBN grindstone?

The CBN grinding wheel is made of cubic boron nitride (CBN), a material second only to diamond in hardness. It is ideal for processing extremely hard materials and is widely used in metalworking and tool sharpening. With excellent wear resistance and heat tolerance, CBN grinding wheels enable high-precision grinding and have a long service life.

These wheels are particularly suitable for processing hard metals like high-alloy steels and hardened steels. To reduce heat generated during high-speed rotation and improve machining accuracy, CBN grinding wheels are typically used with cooling fluids. They come in various shapes and grits, accommodating applications such as surface grinding, cylindrical grinding, and profile grinding.

CBN grinding wheels are extensively used in industries requiring precise machining, such as automotive, aerospace, cutting tools, and mold manufacturing. Their high performance contributes to increased productivity and cost savings in machining processes.

Application of CBN grindstone

✅ Resharpening Cutting Tools
CBN grinding wheels are used to precisely resharpen cutting tool edges, restoring their performance. This extends tool life and improves production efficiency.
✅ Finishing Grinding of Hard Components
Used for grinding automotive components like crankshafts and gears made of hardened steel, achieving high dimensional accuracy and surface finish. This enhances the durability of the parts.
✅ Machining Aircraft Engine Components
Applied in the grinding of turbine blades for aircraft engines, where heat resistance is critical. CBN grinding wheels deliver high machining accuracy and effective heat management.
✅ Precision Machining of Molds
Grinding intricate shapes in press molds or injection molds to ensure high dimensional accuracy. CBN grinding wheels improve mold quality and reduce processing time.
