Long Life of the Tool

In recent years, difficult-to-cut materials processing in a variety of fields of rapid development, as a focus on high-tech materials processing research and development of Mitsubishi integrated materials of course, also very early to start the difficult-to-cut materials processing as the theme of product development projects. Among them, the ultra-heat-resistant alloy processing, titanium alloy processing turning blades in the aviation industry has become one of the main research and development objectives.

Aiming at the key problem of cutting edge boundary defect in the processing of difficult cutting materials such as ultra-heat-resistant alloy and titanium alloy, "suppressing cutting edge boundary defect and realizing tool long life" is the main problem that Mitsubishi comprehensive materials overcome.

First of all, in terms of blade shape structure, the most effective factor to suppress the defect at the boundary of the cutting edge is the balance between the size of the front angle and the sharp grinding of the cutting edge. In order to achieve long life, boundary defects must be continuously suppressed until the end of the process after repeated testing, the introduction of FS/LS/MS/RS-based a variety of ultra-heat-resistant alloys for a variety of operating conditions of sharpness and edge strength of the best blade shape. Secondly, in material development, from carbide substates to coatings have made a new development, upgrading. The new PVD coating "High Al-(Ti) N single-layer coating", Al content is much higher than in the past (Al, Ti) N, surface hardness increased, heat resistance increased, ultra-heat-resistant alloy processing can play the greatest effect, front and rear face wear resistance is excellent. And the coefficient of friction is low, can play an excellent bond resistance. Performance is improved by more than 25% compared to previous products. The combination of high-quality materials and optimum cutting edge shapes further improves the performance of blades for difficult-to-cut materials.

The MP/MT90 series is available in a variety of shapes as an ISO blade series for turning. According to the increasing demand for hard-to-cut materials, the MP9025 material, which attaches great importance to the stability of the tip, is added in 2020, complete with a combination of various materials and chip slots, from finishing to roughing, from continuous cutting to intermittent cutting. Its excellent processing performance, reliable product stability, in aerospace, medical and other industries, received a high price.

Specifically involved in the industry and processed materials are as follows: Inconel718, Wasploy alloy, HAYNES alloy, high-temperature nickel-based alloy GH2132 and other materials mainly in the aerospace industry engine parts and other parts; and other automotive industry-based turboshells, turbocharged system parts, intermediate shells, engine exhaust pipes, throttles and other processing;

Let's show you a few specific chip cases. For example, in the processing of an ultra-heat-resistant alloy aviation parts in China, Mitsubishi MP9005 blade PK European brand products without burrs, small size changes, cutting performance obviously won, and the price also has a greater advantage. In the case of aeronautical parts that precipitate hardened stainless steel, mitsubishi MP9015 has low cutting resistance, good chip breaking, and a 50% increase in life compared to the same type of japanese product. In the aerospace field difficult nickel-based alloy intermittent processing comparison, under the same conditions, the use of the new MP9025 material in 2020, blade damage resistance superior, life of the original Japanese brand 2.5 times. In the automotive parts turbine shell end face roughing, Mitsubishi MP9015 with RS chip-breaking grooves, processing stability significantly exceeds a European and American brand, while the price advantage is large, so that customer costs are greatly reduced. In the arc surface machining of the engine valve valve, the cutting speed of MP9015-MS is increased by 60% at the same time, and the life is 1.5 times that of the original Japanese brand. In the medical industry titanium alloy parts processing case, the use of Mitsubishi uncoated MT9005 material, blade surface for mirror treatment, adhesion resistance, good processing stability, life increased by 1 times. Reduce the number of knife changes in the centrist machining, which greatly reduces the cost. Mitsubishi's MP/MT90 series has had a number of specific success stories in a number of industries around the world since entering the market, including our customers.

Mitsubishi Integrated Materials has always been committed to the development of high-tech materials processing, for difficult-to-cut materials not only in turning, in recent years, drilling, milling new products have also been launched, feedback in various regions of the world is very good.
