According to the survey, there are dozens of companies in China that are involved in the production of heavy-duty machine tools, which is unique in the world. The products produced cover almost all types of heavy-duty machine tools. The market share in China is over 85%, and the market variety meets more than 90%. Although the import is effectively restricted, the middle and low-grade products account for the varieties available. More than 60%, while medium and high-end products account for only 30%, and imported products account for 10%.


According to incomplete statistics, the annual production capacity of the main products of China's heavy-duty machine tool industry is: vertical lathe (1250mm or more) about 1500 sets / year; heavy horizontal lathe (1200mm or more) about 500 sets / year; horizontal boring machine (130mm Above) and floor milling boring machine (160mm or more) about 1200 sets / year; heavy gantry boring and milling machine (2000mm) 1500 sets / year; hobbing machine (2000mm or more) 100 sets; roll grinder (1200mm or more) 200 sets. At present, the production capacity of the industry has been seriously oversupplied, and the market will face more fierce and fierce competition.

At present, the market demand and market environment change very much. The demand characteristics are that the demand ratio of medium and high-end CNC machine tools is increasing. It is mainly composed of high-speed, high-precision, intelligent and environmentally-friendly composite processing machine tools. At the same time, the market has released a new demand situation, and the demand for technical services is more urgent, that is, the integrated turnkey project with equal emphasis on equipment and process, software design and remote service, requires the host manufacturer not only to provide hardware, but also to Providing software and process technology services, the future market will pay more attention to technical services, and the technology-centric marketing model will replace the traditional product marketing model.

The transformation and upgrading of China's heavy-duty machine tool industry is imminent, and there is no time to delay. Enterprises should realize that the production capacity of the industry is seriously overcapacity. The company should be market-oriented, start from management, innovation, and adjust product structure, change business philosophy, change to technology-intensive business model, and accelerate product technology upgrade, including product structure. Design optimization, functional improvement, precision improvement, manufacturing process optimization, lean production, optimization of materials and functional components and accessories. Among them, the precision of the machine tool, the level of manufacturing technology and the reliability need to be improved, which is the most important reason for the domestic heavy-duty machine tools to be passive in the market competition.

Technology upgrade is to adapt to the market and meet the needs of the market. It must focus on key industries such as aviation, aerospace, military, shipbuilding, energy, railway, rail transit, etc. These industries have high requirements for heavy-duty machine tools, especially for medium and high-end CNC machine tools. The largest and most influential industries need to be imported, and these industries should be targeted at tracking targets and industry sectors as a technology upgrade for heavy-duty machine tools.

Manual Directional Valves

Manual Directional Valves type WMM & WMR are lever operated Directional Spool Valves. They control the start, stop, and direction of a flow. These directional valves basically consist of housing; lever; control spool; return springs. A full array of spools are possible with variations for detented operation on both 2-position or 3-position functions. Flow and pressure rates from 4000 PSI to 5000 PSI and 16 GPM to 32 GPM cover a wide range of applications.

Features:

l  Size 6 and 10

l  For mounting:

l  Size 6: Porting pattern according to ISO 4401-3, NFPA T3.5.1M R1, and ANSI B 93.7 D 03

l  Size 10: Porting pattern according to ISO 4401-5, NFPA T3.5.1M R1, and ANSI B93.7 D 05

l  Operation by means of manual lever
