加工铸铁的Widlanit切削材料主要由氮化硅(Si_3N_4)组成。它兼有硬质合金的韧性和氧化物陶瓷材料的热硬性。在加工铸铁时(图),切削速度可超过1000米/分。粗铣时,尽管出现微小的碎裂现象,但仍是一种良好的切削材料。Widianit切削材料有相当高的抗冲击强度(即高韧性)、特别高的热硬性,高硬度和耐磨性以及良好的化学稳定性。采用这种切削材料不仅能获得更高的切削速度,而且还能提高刀具寿命。因此,降低了加工费用。同时,这种良好的韧性可提高加工的可靠性。尤其在越
Widlanit machining of cast iron is mainly composed of silicon nitride (Si_3N_4). It combines the toughness of cemented carbide with the thermosetting properties of oxide ceramic materials. In the processing of cast iron (Figure), the cutting speed of more than 1,000 m / min. Rough milling, despite minor fragmentation, is still a good cutting material. Widianit cutting materials have very high impact strength (ie, high toughness), particularly high thermostability, high hardness and abrasion resistance, and good chemical stability. Using this cutting material not only achieves higher cutting speeds, but also increases tool life. Therefore, the processing cost is reduced. At the same time, this good toughness increases the reliability of the process. Especially in Vietnam
