Surface grinding wheels for magnetic materials are specifically engineered for high-precision grinding of both hard and brittle magnetic components as well as soft magnetic alloys. These wheels ensure excellent flatness, tight thickness tolerance, and superior surface finish while minimizing edge chipping and thermal damage.
They are widely used in industries such as electronics, motors, new energy, and precision components manufacturing.

We provide tailored solutions based on:
Material type (NdFeB, ferrite, SMC, etc.)
Machine type (surface grinder, double disc grinder)
Required surface finish & tolerance
Production volume and efficiency requirements
| Material Type | Recommended Bond Type | Reason |
| NdFeB (Neodymium Magnets) | Resin / Vitrified | Brittle, prone to chipping |
| Ferrite | Resin | Requires fine surface finish |
| SmCo | Vitrified / Resin | Hard & brittle, needs stability |
| Soft Magnetic Alloys | Vitrified / Metal | Higher efficiency, less brittle |
| SMC Materials | Vitrified | Requires balance of efficiency and finish |
Use Resin Bond (D151–D3000) for precision finishing and tight tolerance control
Use Vitrified Bond (D46–D181) for automated production lines with stable output
Use Metal Bond (D36–D91) for rough grinding and long tool life requirements
