The new material grade TP1500 for turning inserts is the DuratomicTM coating technology pioneered by Seco at the end of 2006. The features of the front and back knives are black, which has attracted many users, but its core atomic control technology has not been used yet. Competing. The TP1500 is suitable for turning steel parts. Among the nearly 100 cases of different applications in the TP1500 field test, the obvious advantage is 80%, and the effect is 13%. Combined with the TP1500, the MR6 chipbreaker makes a special design of the chipbreaker for high-speed feed time. Under the same cutting parameters, the cutting heat and cutting force are lower than the chipbreaker of similar applications. M5 and MR7, and a wider working range, can increase cutting speed and extend tool life.
