New concept of cutting
Today's tool companies can no longer just manufacture and sell tools. In order to succeed, they must keep in line with global manufacturing trends and reduce costs by improving efficiency and cooperating with customers. In this post-NAFTA and post-WTO era of almost instant global competition, companies all over the world are responding to the same feeling faster, lighter, and cheaper. In other words, the products and parts they manufacture include those that can run at high speeds, and due to cost pressures, they are best, lighter, and cheaper to manufacture. One of the best ways to achieve these goals is through the development and application of new materials, but these new and improved materials are often difficult to process. This combination of commercial power and technical difficulties of the Guangdong mechanical processing plant is particularly prominent in the automotive and aerospace industries, and has become the primary driving force for the R&D departments of knowledgeable tool companies.
For example, in the case of ductile iron, the Dongguan CNC processing plant has become an increasingly common material for engine parts and other parts in the automobile, agricultural equipment, and machine tool industries. This alloy offers a combination of lower production costs and good mechanical properties. They are cheaper than steel and have higher strength and toughness than cast iron. But at the same time, ductile iron is very wear-resistant and has a tendency to quickly wear tool materials. This wear resistance is largely affected by the pearlite content. The higher the pearlite content of a known ductile cast iron, the better its wear resistance and the worse its workability. In addition, the porosity of ductile iron leads to intermittent cutting, which further reduces the life span.
It can be predicted that the high hardness and high wear resistance of the Dongguan CNC processing plant needs to consider the high wear resistance of ductile iron. And the fact that the material contains extremely hard TiC (titanium carbide) or TiCN (titanium carbonitride) thick coatings at a cutting speed of 300 meters per minute is generally proven to be effective in machining ductile iron. However, as the cutting speed increases, the temperature of the chip/tool interface also increases. When this happens, the TiC coating tends to chemically react with the iron and soften, and more pressure is applied to the anti-crescent coating. Under these conditions, it is desirable to have a chemically more stable coating, such as Al2O3 (although it is not as hard or wear-resistant as TiC at lower speeds).
