摘要 |
An outer blade cutting wheel comprising an annular thin disc base of cemented carbide and a blade section of metal or alloy-bonded abrasive grains on the outer periphery of the base is provided. The abrasive grains are diamond and/or cBN grains having an average grain size of 45-310 μm and a TI of at least 150. The blade section includes overlays having a thickness tolerance (T3max−T3min) of 0.001 mm to 0.1×T2 mm. The blade section has a roundness (ODmax/2−ODmin/2) of 0.001 mm to 0.01×ODmax mm.
