According to the Nikkei BP News Agency: Japan's Tungaloy (headquarters: Kawasaki City) listed a large chip breaker "HMM" in the front corner, especially suitable for heat-resistant alloys with increasing demand in the aircraft field and hard-to-cut heat resistance. Turning of alloys. In addition to the work on the shape of the front corner, new materials are used to extend tool life.
In general, when a heat-resistant alloy is processed, abnormal damage is likely to occur at the cut-in boundary, and the dynamic component of the cutting resistance is large, so that the tool life is likely to be shortened. Therefore, the new chip breaker is provided with a dot-like projection on the large rake angle and the rake face having a sharp edge. This reduces the rubbing area with the chips and suppresses the rise in the cutting temperature and the welding.
The material is a coating material "AH905" based on cemented carbide. This material is coated with an (Al,Ti)N film with excellent high-temperature characteristics and high hardness, high adhesion and smoothness, which improves wear resistance compared to the original material. It can stably process heat-resistant alloys and is expected to extend tool life and improve machining efficiency. The product is available in 20 models and starts at 893 yen (tax included).
