The machine tool industry is mainly used in the front end of the manufacturing industry, benefiting from economic growth and industrial upgrading. In general, when the downstream industry is just beginning to recover, the demand for machine tools is relatively small; when the downstream economy rapidly increases and the production capacity expands rapidly, the demand for machine tools begins to be released on a large scale, so the machine tool is relatively lower than the downstream industry. After the cyclical industry. Historical data also show that the growth of the machine tool industry is clearly driven by industrial production and lags behind industrial production. Shenyang and Dalian have become the most important development and production bases for CNC lathes and machining centers nationwide.
According to Luo Baihui, Secretary-General of the International Model Association, the NC machine tool industry in the Northeast has played a pivotal role in the country and has always been a nationally supported project.
The machine tool output value of the two machine tools of Shenyang Machine Tool (Group) Co., Ltd. and Dalian Machine Tool Group Co., Ltd. accounted for 26% of the national machine tool output value. The output of CNC gold-cutting machine tool accounted for 25.4% of the national CNC machine tool production. The output of CNC lathes accounted for about CNC of the country. 35% of lathe output and processing center production accounted for about 21% of the national machining center's output.
The large and heavy-duty CNC lathes produced by Qizhong CNC Equipment Co., Ltd. account for approximately 48% of the country's large and heavy-duty CNC lathes, and the output value accounts for approximately 50% of the country's large and heavy CNC lathes. The large and heavy-duty CNC boring mills produced by Qiqihar No.2 Machine Tool (Group) Co., Ltd. account for about 35% of the country's CNC boring machine production, and the production value accounts for approximately 30% of the national CNC boring machine output value.
Taking Harbin as the mainstay, it has formed a national production base for tools and special complex tools. Its representative companies are Harbin Measuring & Cutting Tools Group Co., Ltd. and Harbin No. 1 Tool Co., Ltd.
The “12th Five-Year Plan†development goal of the machine tool industry clearly points out that it has taken a big step toward a powerful machine tool industry, significantly improved its industrial structure, and significantly improved its product structure. However, considering from the opposite perspective, when the downstream industry's economy declines, the downstream industry quickly shrinks capital expenditures, and the demand for machine tools declines earlier than the downstream industries.
The broad application areas of machine tools are railway locomotives, automobiles, construction machinery, and power equipment. Luo Baihui said that the industrial upgrading of various sub-sectors of the equipment manufacturing industry in China is inseparable from the support of the machine tool industry. The machine tool industry is an important pillar industry that cannot easily be abandoned in the economic development strategy. For the machine tool industry, it is the basic equipment for the equipment manufacturing industry, the working machine for the equipment manufacturing industry, the carrier for advanced manufacturing technology and the basic production method for the equipment industry.

Channel steel connectors are a commonly used connecting component used to connect channel steel and other components. Common classifications can be introduced from the aspects of material, use, and application.
1. Material classification:
-Steel connectors: Made of steel, with high strength and durability.-Stainless steel connectors: Made of stainless steel, with corrosion resistance and aesthetics.
-Aluminum alloy connectors: Made of aluminum alloy, they are lightweight, corrosion-resistant, and thermally conductive.
2. Usage classification:
-Bolted connections: By combining bolts and nuts, the channel steel and other components are connected together.-Welding connectors: Connect channel steel and other components together by welding.
-Bolted welded connectors: Combining the characteristics of bolted and welded connections, they have both the detachable nature of bolts and the firmness of welding.
3. Application classification:
-Structural connectors: used to connect channel steel and other components, and used in Structural engineering of buildings, bridges, machinery and other fields.-Support connector: used to connect channel steel and support components, to support the stability and safety of the structure.
-Fixed connectors: used to fix channel steel and other components, for fixing equipment, pipelines, etc.
Overall, the classification of channel steel connectors can be based on material, usage, and application. Different classifications have different characteristics and applicability, and suitable connectors can be selected according to specific needs.
