Everything You Need to Know About Cut-off Wheels

Resin-bonded super abrasives cut off wheels, consisting of diamond or cubic boron nitride (CBN) abrasives and a resin binder, are indispensable cutting tools for industrial cutting, widely applied in the precision processing of hard and brittle materials.

What are cut-off wheels?

Resin-bonded superabrasives cut-off wheels are high-performance cutting tools, they are typically designed in shapes such as 1A1R, 1A8, 3A1R, or 14A1R to adapt to different cutting needs. During the cutting process, the high hardness of diamond or CBN abrasives enables them to quickly penetrate materials, while the elasticity and strength of the resin matrix ensure the durability and stability of the wheels. Whether for metals, ceramics, or stones, resin-bonded superabrasive cut-off wheels provide efficient and precise cutting results.

What are cut-off wheels made of?

Resin-bonded super abrasives cut-off wheels consist of diamond or CBN abrasives and a resin binder. Diamond is the preferred choice for cutting hard, brittle materials due to its unparalleled hardness, while CBN excels in high-speed cutting ferrous metals due to its good thermal stability and wear resistance. The resin binder securely bonds these abrasives together to form a stable cutting surface.

Different types of angle grinder discs

Diamond cut-off wheel for die grinder: Tungsten carbide, silicon, glass, ceramic, sapphire and semiconduction materials.

CBN cut-off wheel: Cut the material that includes ferrous metal elements like high-speed steel, mould steel, the steel material, and hardness is more than 55 HRC.

Best Practices for Cutting Disc Safety and Troubleshooting

When using resin-bonded cut-off wheels, ensure they are correctly installed and adjusted to the appropriate cutting speed and pressure. Regularly check the wear condition of the die grinder abrasive wheel and replace those that are severely worn to avoid potential safety hazards. Additionally, maintaining a clean and well-ventilated work area is also an important safety measure. When encountering issues such as poor cutting performance or wheel damage, promptly analyze the causes and take corresponding solutions, such as adjusting cutting parameters or replacing suitable wheel types. By following these safety precautions, the lifespan of resin-bonded cut-off wheels can be maximized, and cutting operations can be performed safely and efficiently.
