AG_2新型复合陶瓷刀具不仅具有硬度高(HRA93.5～95),耐磨性好(红硬性达1100℃),而且还具有足够的抗弯强度(σ_b≥800MPa),优良的化学稳定性,对钢的亲和力小与钢的焊接温度高(1538℃)等特点。因此,它是加工高强钢、淬硬钢、合金钢、白合金耐磨铸铁等难加工材料的理想切削刀具。在水利电力部修造企业技术情报网和中南工业大学的大力支持和指导下,我厂从1984年开始推广使用AG_2金属陶瓷刀具,用于精车和
AG_2 new composite ceramic tool not only has high hardness (HRA93.5 ~ 95), good wear resistance (red hardness up to 1100 ℃), but also has sufficient bending strength (σ_b ≥ 800MPa), excellent chemical stability, The small affinity of steel and steel welding temperature is high (1538 ℃) and so on. Therefore, it is an ideal cutting tool for the machining of difficult-to-machine materials such as high strength steel, hardened steel, alloy steel and white alloy wear-resistant cast iron. Under the support of Ministry of Water Conservancy and Electric Power Ministry of Construction Technology Information Network and Central South University of Technology, our factory has promoted the use of AG_2 cermet tools since 1984,
