Hot alloys are typical difficult-to-machine materials and can even be said to be the most difficult materials to cut in difficult-to-cut materials. The difficult machining is mainly caused by high cutting temperature, large cutting force, serious work hardening, easy tool wear and low production efficiency. Therefore, high temperature alloy processing tools are the key to solving the difficult problem of high temperature alloy processing.
After we fully understand the properties and cutting characteristics of the processed hot alloy materials, we can properly select the cutting tools and cutting conditions to complete the cutting process.

Based on the traditional PVD coating process, Zhuzhou Diamond has studied from multiple aspects and multiple layers, breaking through the plasma-enhanced nano-multilayer modulation periodic structure PVD technology. The optimized modulation period of YBG102 nano-multilayer structure coating is remarkable. Reduce to the nanoscale.
For the processing of high-temperature alloys, on the one hand, in the cutting process, especially the turning processing requires good wear resistance, and the heat generated in the processing of materials such as heat-resistant alloys is high, and the materials are required to have good heat resistance.
Therefore, in the aspect of the substrate, in order to select a low Co content for high wear resistance, the high temperature resistance to plastic deformation is improved by using fine particle WC and adding an appropriate amount of TaC cubic phase to further improve high temperature performance. Therefore, YBG105 has been developed, and the performance of YBG105 is 30% higher than that of YBG102. It fully exceeds and meets the requirements of on-site finishing, semi-finishing and roughing.

high temperature alloy machiningYBG105: PVD coated grade, quaternary TIALN nano-coating, which improves the wear resistance of the tool and is suitable for continuous fine and semi-finishing turning of high temperature alloy.
YBG102: PVD coated grade, Nc-TiAlN coating combined with fine grain matrix, suitable for continuous fine and semi-finishing turning of superalloy.
YBG series processing high temperature alloy tool introduction:
YBG212: PVD coated grade, high wear-resistant TiAlN coating tightly bonded to the substrate for higher toughness and hardness. Good thermal and chemical stability of the coating provides more effective protection for the cutting edge. High toughness ultra-fine carbide substrate with good edge strength. Suitable for interrupted turning of high-temperature alloys, and milling of titanium alloys and high-temperature alloys.
