Opening up the tool market in the field of large precision machining

Back to list 发布日期:18年06 月23日 Source: Jindong Metal Products Release Date: June 23, 2018

Common tools in the Chinese market are high-speed steel tools, hard alloy tools, cermet tools, and PCD / PCBN super-hard tools. Except for complex forming tools such as blade root milling cutters, gear hobs, broaches, and taps, high-speed steel tools are mostly low-end tools with large quantities and low value. With the rapid upgrading of China's manufacturing industry, the continuous promotion of advanced cutting technology and hard alloy tools, high-speed steel tools have been shrinking in the domestic market, and their share is currently less than 60%; cermets are maintained in the precision turning of steel and cast iron. Advantage, its market share is about 2%; ceramic tools have been promoted in the field of high-speed milling, especially aviation difficult to process materials, accounting for about 1% of the market share; the market share of PCD / PCBN superhard materials is about 2%, mainly Focus on the processing of non-ferrous metals and ferrous metals.

The current status of hardened drills. The drilling process is the forming process under the conditions of poor cooling and chip removal. The technical requirements are high, so the added value of the drill product is also high. The products of high-end hardened drills are mainly used in automobiles, aviation, engineering machinery, high-speed rail, power equipment, power equipment, refrigeration equipment and other high-end precision machining fields.

Only a few cutting tool companies in China can enter these high-end manufacturing fields and compete with international first-tier brands. For example, in the field of automobile engine manufacturing, where the tool requirements are the most stringent, the domestic brands that can often be seen are only a few companies such as Suzhou Anuo, Zhuzhou Diamond, and Shanghai Tool Factory. In recent years, Suzhou Anuo has developed rapidly. In addition to the production of non-standard drill bits, standard hardened drill bits have been produced and sold in 2011. Even in other precision manufacturing fields, only Zhuzhou Diamond and Suzhou Anuo's hardened drills compete with first-tier international brands on the same stage. According to rough statistics, the market demand for high-end hardened drill bits in China was about 900 million yuan in 2010, while the localization rate of high-end hardened drill bits was only about 15%.

At present, the common high-end hardened drill bits in the Chinese market mainly come from industrialized countries such as Europe, the United States, and Japan, such as Sandvik, Kenner, Cobalt Collar, Titex, Mapa, and Japan's Mitsubishi, Sumitomo, and Oishi. . According to a survey by Luo Baihui, Secretary General of the International Mould Association, most of these companies have large stocks of standard drills in Singapore or the mainland, and they also put some non-standard drills in China. The quality of drill products in South Korea and Taiwan is not strong, so it is rare in the market.

In fact, the vast majority of carbide tool companies in China, including private knife companies, state-owned tool factories, and Taiwanese knife companies in the mainland, produce solid end mills. Domestic solid end mills occupy most of China's low-end market at a lower price, and 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 Chinese rigid end mills and the world's first-line brand tools, such as: milling cutters for high-hardness materials, high-speed milling cutters, titanium Alloy milling cutter, graphite milling cutter, aerospace synthetic milling cutter, precision milling cutter, etc. These rigid end mills have a high added value, and the main market share is occupied by foreign manufacturers, such as Sandvik, Kenner, Daijie, Hitachi, Frasa, Prototyp, SGS, Jabro, OSG, Hanita, LMT and so on.

According to incomplete statistics, the Chinese market had about 1.5 billion yuan of demand for high-end rigid end mills in 2010, and the localization rate was close to 30%. The current challenges and areas that need improvement include: mechanical and structural characteristics: hardness, strength, wear resistance; thermal and chemical characteristics: heat resistance, insulation, and catalytic properties; biological characteristics: adaptability, insecticidal properties Electronic and optical properties: reflective, transparent, etc.

"In recent years, Ti and Al-coated carbide tools have dominated the high-performance tool market. The high demand for certain special applications has promoted the development of special coatings or precision coatings." Association Secretary-General Luo Baihui pointed out that the gap between Chinese tool companies and foreign companies must be addressed squarely, including basic technology, innovation ability, promotion ability and service ability. User needs and cutting tool companies should become innovation leaders, and leading companies should take the lead in demonstration in the field of technology applications. However, Shen Zhuangxing said that some key domestic enterprises and new excellent private enterprises have taken a very gratifying step in the development of modern and efficient cutting tools, such as Zhuzhou Diamond, Xiamen Jinlu, and Anuo Cutting Tools. These companies attach great importance to technological progress and will serve In the first place, significant results have been achieved in related fields.
