In order to meet the needs of tool companies, they must have "one skill". In today's China's mechanical processing field, the four industries of aerospace, automotive industry, mold manufacturing, and electronics industry are places where CNC machine tools and tools are concentrated, but in these industries. Most of the tools used are occupied by imported brands, and these foreign brands have won the trust of customers by relying on their housekeeping skills. In the aerospace industry, Kennametal is doing very well in the field of heat-resistant "super-strong alloys", from the early development of PVD coatings KC730 and KC732 to the later PVD coatings KC5510 and KC5525 (corresponding to 12° positive rake angle) The finishing FS and the semi-finished MS geometry of the 13° positive rake angle are the world's best in terms of cutting speed and blade durability. In the automotive industry, ductile iron parts have become the mainstream. In the improvement of processing ductile iron, Seco was the first to develop. Its TK1000 and TK2000 materials for ductile iron processing are ideal for processing ductile iron. Walter's new "silver" The Tiger Blade has also greatly improved the cutting efficiency. Others such as Sandvik Coromant, Isca, Sumitomo Electric and Yan Jie also have unique cutting tool products in cast iron processing. Mold manufacturing is the most used in the mold manufacturing industry. In this respect, Walter, Iskar, Mitsubishi Materials and Yujie Industrial have a comprehensive range of products, including more than 21 types of Walter mold cutters. Almost all processes in mold processing; Japanese tools have great advantages in the field of tools for the electronics industry. With the rapid development of China's IT industry, Japanese tool manufacturers have increased production to meet the cutting needs of China's IT industry, such as Tailuo, Enterprises such as Mitsubishi and OSG have established factories or joint ventures in China. Many imported brands have achieved a certain market position after having a certain unique ability, and the products are gradually starting to be fully serialized. The most powerful proof is Iskar and its famous "Overlord Knife", which was first named after its self-developed "SELF-GRIP" self-locking grooving knife, followed by a grooving knife. A large number of products have been researched and developed, and it has become the most complete and most complete brand in the field of grooving and cutting knives in the world. It is a leader in this field and has rapidly risen in the tool market and has a worldwide reputation. Others, such as Germany's Marpa company, have dominated the domestic automotive engine manufacturing industry with high-precision reamer and non-standard hole machining tools, becoming an irreplaceable product. For local companies, although they started late in the field of high-precision CNC tools, in some sub-cutting tools, some domestic enterprises have stable product quality and are gradually replacing imported products. For example, the drill is a unique show in the field of indexable inserts. There are many blade products and specifications for turning, grooving, threading, milling and drilling. It is also more powerful in the field of indexable tools. Domestic solid carbide tools have also made great breakthroughs. Arno's drills, reamers, end mills and combination tools have been benchmarked in the industry, especially non-standard drills have been used in domestic automobiles and aviation. In precision manufacturing, it is widely used to replace imported products; Zheng Diamond has done a very good job in the field of super-hard tools. PCD and PCBN super-hard tools have won considerable user recognition, and the performance of welding blades has basically reached the international level; In the field of complex tools, Ha Yigong and Hanjiang tools have done a good job. The emerging company Jiaxing Hengfeng has created extraordinary achievements with its complete series of spline measuring tools and complex tools. The plant is hard and the golden heron is the leader in the Chinese bar industry. The general solid bar and the linear inner hole bar are basically close to the international standard, and the cold bar and grain are high in the technical content and the added value. High-end bars less than 0.3 microns are missing.
