The development of China's machine tool industry has on the one hand the world's largest industrial scale. On the other hand, it faces the situation that the domestic high-end market, especially the high-end market, still relies on imports. In particular, the dependence of medium-to-high-end CNC systems and major functional components on imports is even greater. high. Under the strategic background of the country's adjustment of the industrial structure, the machine tool industry can not only be positioned in terms of scale expansion and the increase in the amount of production and sales. What is important is how much of the industry's core technologies are mastered, what are the advantages of brand competitiveness, and the resource consumption and energy of products. The rate of utilization of social contribution rate. Therefore, machine tool companies must quickly move out of the erroneous zone of extensive product growth and industrial numbness expansion, and vigorously shift towards quality and efficiency.
At present, the domestic machine tool manufacturing enterprises are generally large and not strong, while the functional components and numerical control system enterprises are neither big nor strong. Now many domestic machine tool companies think that their products are not enough for secondary development on the CNC system, but only use those functions on the standard platform, even if the same high-end CNC system is used, the domestic machine tool application level and adaptation The scope is also limited. This is mainly due to the deficiencies in our overall R&D system, etc. It is still difficult to fully upgrade the industrialization level of domestically produced high-end CNC cutting machine tools in the short-term.
At present, China's machine tool industry suffers from the dual effects of the global economic downturn and the adjustment of domestic industrial policies, and has experienced a sharp decline. In 2012, the machine tool industry showed a trend of low growth and high growth. The sustained and prosperous domestic market demand in the low-end market slowed the growth rate of the industry to some extent. The industry still has not fundamentally shaken off the development model with scale expansion as the main feature. Although our industry has a large scale, the level of product structure is low and it is still at the low end of the global industrial chain.
On the whole, it can be said that the basic characteristics of the industry at this stage are “big but not strongâ€. At this stage, the main contradiction of the industry is the contradiction between the accelerating upgrade of the domestic market demand structure and the industry's supply capacity. Therefore, the machine tool companies must improve the localization of the middle-to-high-end numerical control systems and core functional components and the market share, and further improve the overall level of support for the company. It is necessary to focus on the improvement of traditional equipment technology focusing on improving product performance, accuracy, and efficiency as well as reducing energy and raw material consumption, and promote the transfer of traditional products from low to medium-end industries. At the same time, it is necessary to implement lean production with ERP management as the core, and improve the information engineering construction of resource management, manufacturing, and supply chain management.
The next few years will be a critical period for the Chinese machine tool industry to “grow from big to strong.†During this period, China will form a new industry structure represented by high-end machine tools, led by high-end equipment manufacturing, and supported by multiple advanced manufacturing industries. China's machine tool industry as a whole has already entered the frontier of the world, but what we have before us will be more intense competition. It is a long way to go, and it is time to wait. We must work hard to meet more challenges.

Types' Specification
Welding neck
1, Preferred for high-pressure, subzero or elevated temperature
2, Hub is tapered and bored to match pipe's inside diameter so flow is not restricted, preventing turbulence and reducing erosion
3, Easily radiographed and provides excellent stress distribution
Slip-on
1, Not normally used in high-stress applications due to low hub and weld attachment
2, Silps over outside of pipe
3, Inside of flange welded at hub and end of pipe
Lap joint
1, Used where bolt alignment or access for cleaning is required
2, Similar to slip-on flange when used with lap joint stub end
3, Radius at intersection of flange face and bore to match lap joint stub end
Threaded
1, Used where welding would would be hazardous
2, Designed for low-pressure and non-cyclic applications
3, Bore is threaded to match pipe thread
4, Tapered to seal pipe and flanges
Socket welding
1, For small-diameter chemical processes, hydraulic and stream distribution lines
2, Similar to slip-on flange
3, Counter bore matches pipe bore, allowing unrestricted flow
4, Counter bore from hub side fits pipe's outer diameter can insert pipe in socket with fillet weld at hub
Blind
1, Used to close ends of piping
2, Has no bore
3, Permits access to sealed lines
Other flanges
Orifice, Expander, Reducing, Lightweight, Studding Outlets, Long Weld Necks,Metric, Navy Drawings, Customer Drawings
