[Processing Example] Internal Grinding of Cermet Circular Blades

We optimized the selection of diamond grinding wheels for difficult-to-cut materials, achieving a dimensional accuracy of 5μm!

We would like to introduce a case of inner surface grinding of a circular blade made of cermet (TN3) used in cutting machines. Cermet has a hardness comparable to that of carbide, and sufficient grinding performance cannot be achieved with standard grinding wheels, making the selection process challenging until the specifications were met. We selected a grinding wheel suitable for the unique balance of hardness and brittleness of cermet, achieving stable processing while minimizing chipping. 【Case Overview】 ■ Material: Cermet (TN3) ■ Product Size: Inner diameter φ14 ■ Processing Conditions: Inner surface grinding / Dimensional accuracy 5μm (±0.005mm) / Diamond grinding wheel used / Processing time 2.5 minutes per piece ■ Equipment and Model Used: Inner surface grinding machine ■ Others: Lot of 4 pieces / Cutting machine parts *For more details, please download the PDF or feel free to contact us.
