China's tool market opened high-end precision machining field

High-speed steel tools, carbide tools, cermet tools and PCD/PCBN super-hard tools commonly found in the Chinese market. In addition to complex forming tools (leaf-end milling cutters, gear hobs, broaches, and taps), high-speed steel tools are mostly low-end tools with low volume and low value. With the rapid upgrading of China's manufacturing industry, advanced cutting technology and the continuous promotion of cemented carbide tools, high-speed steel tools are shrinking in the domestic market, and its current share is less than 60%; cermets remain in precision turning of steel and cast iron. Advantages, its market share is about 2%; ceramic tools are promoted in high-speed milling, especially in the field of aviation difficult-to-machine materials, accounting for about 1% of the market; the market share of superhard material PCD/PCBN is about 2%, mainly Focus on the processing of non-ferrous metals and ferrous metals. The current state of the hard drill bit is the forming process under the condition of poor cooling and chip evacuation conditions, and the technical requirements are high, so the added value of the drill bit product is also high. High-end hard bit products are mainly used in automotive, aerospace, engineering machinery, high-speed rail, power equipment, power equipment, refrigeration equipment and other high-end Precision Machining. Only a few tool companies in China can enter these high-end manufacturing fields and compete with international first-line brands. For example, in the field of automobile engine manufacturing where the most demanding tools are required, the domestic brands that can be seen frequently are only a few companies such as Suzhou Arnold, Zhuzhou Diamond and Shanghai Tool Factory. In recent years, Suzhou Arnold has developed rapidly. In addition to producing non-standard drill bits, it has started to produce and sell standard hard drill bits in 2011. Even in other precision manufacturing fields, only Zhuzhou Diamond and Suzhou Arnold's hard drills compete with international first-line brands. According to rough statistics, in 2010 China had about 900 million yuan of high-end hard drill bit market demand, and the localization rate of high-end hard bit was only about 15%. At present, the high-end hard bits commonly found in the Chinese market are mainly from industrial developed countries such as Europe, the United States, and Japan, such as Sandvik, Kenner, Cobalt, Titek, Mapa, and Japan's Mitsubishi, Sumitomo, Oushi, etc. . According to Luo Baihui, secretary general of the International Model Association, most of these companies have large stocks of standard drill bits in Singapore or the mainland, and some non-standard drills are also produced in China. The quality of drill products in Korea and Taiwan is not strong, so it is rare in the market. The gap between most domestic tool companies and international first-line tool brands in terms of hard bits is mainly in design concept, manufacturing details, material selection and coating treatment. The specific products with the biggest difference in drill performance at home and abroad are: drill bits for processing steel parts, deep hole twist drills for replacing gun drills, drill bits for processing high temperature alloys and high hardness steels. In these areas, only a few companies in China have mastered design and manufacturing techniques. The current state of the hard end mill can be divided into general-purpose and high-end type. In general, the technical difficulty of the general hard end mill is relatively small, and the gap between product quality and foreign countries is not great. In fact, most of China's cemented carbide tool companies, including private knife companies, state-owned tool factories and Taiwanese knife companies in mainland China, mainly produce hard-end milling cutters. Domestic hard-end milling cutters occupy most of China's low-end and mid-end markets at a lower price, and the competition is fierce. However, in some high-end manufacturing fields such as difficult machining and high-speed milling, there is still a certain gap between the quality of China's hard end mills and the world's first-line brand cutters, such as milling cutters for high-hardness materials, high-speed milling cutters, and titanium. Alloy milling cutters, graphite milling cutters, aerospace composite milling cutters, precision milling cutters, etc. These hard end mills have higher added value and the main market share is occupied by foreign manufacturers such as Sandvik, Kenner, Yan Jie, Hitachi, Frasa, Prototyp, SGS, Jabro, OSG, Hanita, LMT, etc. According to incomplete statistics, in 2010, there was about 1.5 billion yuan of high-end hard-end milling cutters in the Chinese market, and the localization rate was close to 30%. The current challenges and areas for improvement include: mechanical and structural properties: hardness, strength, wear resistance; thermal and chemical properties: heat resistance, insulation, catalytic properties; biological properties: adaptability, insecticidal properties Electronic and optical properties: reflectivity, transparency, etc. “In recent years, (Ti, Al) coated cemented carbide tools have dominated the high performance tool market. The high demand in some special applications has facilitated the development of special coatings or precision coatings.” Luo Baihui, secretary-general of the International Model Association, pointed out that it is necessary to face up to the gap between Chinese tool companies and foreign companies, including basic technology, innovation capabilities, promotion capabilities and service capabilities. The user demand and the tool enterprise should be the innovation leader, and the leading enterprises should take the lead in demonstrating the role in technology application. However, Shen Zhuangxing said that some key domestic key enterprises and new excellent private enterprises have taken a very gratifying step in the development of modern and efficient tools, such as Zhuzhou Diamond, Xiamen Golden Heron and Arno Tools. These companies attach importance to technological progress and will serve In the first place, it has achieved remarkable results in related fields.
