Mitsubishi Materials has long been conducting research and development work to improve tool cutting performance by using coated tool surface smoothing technology, and has implemented a number of research and development results. As the first surface smoothing technology applied to the product, the surface smoothing technique of mechanical treatment was carried out after CVD coating on the blade grade US7020 for high-speed turning stainless steel. After coating a tough hard alloy substrate with a multi-layer hard film mainly composed of a columnar crystal TiCN film and a fine particle A12O3 film, the coated tool shows excellent cutting performance in the cutting process of stainless steel. In addition, the surface smoothing technique as described above is used to effectively inhibit the bonding of the material to be cut on the cutting edge. For stainless steel machining, stable tool life is guaranteed even under high-speed cutting conditions of V = 200 m/min.

In addition, surface smoothing techniques can also be used on representative blade grades UE6010 and UE6020 for turning steel. The surface smoothing technique applied to the above materials is called “smooth coating technology†and uses a special CVD technique to obtain a smooth coating surface by controlling the growth of the coating. It is a non-mechanical treatment that achieves smooth surface finish without damaging the coating.
3 The best "all black super smooth coating" technology
On the latest insert grades UC5105 and UC5115 for turning cast iron, the unique chemical treatment of surface smoothing technology and mechanical smoothing technology combined with a comprehensive surface treatment technology - "all black super smooth coating". The use of this technology maximizes the smoothness of the surface of the coating.
In addition to the smooth surface technology, another new coating material with high wear resistance technology is also suitable for the above grades. Ductile iron is one of the most difficult materials to cut for cutting tools. However, due to the application of the UC5105 and UC5115 grades, the abnormal damage of the tool is greatly reduced, and the problem of processing the ductile iron is solved. In addition, the application of the UC5105 grade with high-hardness cemented carbide as the base material makes it difficult to complete the high-speed machining of cast iron in the field of ceramic tool cutting.
This article takes Mitsubishi Materials as an example to introduce the application of surface smoothing technology in coating technology development. In the future, we will continue to conduct in-depth investigations into market demand and develop coating technologies that meet market demands in order to meet the market demand for coated tool products.
