in the past few years, china’s shipbuilding industry realized the leap-forward development in the international shipping market is becoming increasingly important. in particular, in 2008, the chinese shipbuilding shipbuilding industry not only in quantity, at the end of handheld shipbuilding orders made great achievements, but also in the economic scale, economic benefits, such as independent research has also made a breakthrough. in innovation, high technology ships and ocean engineering equipment, construction of new breakthroughs in research and development: first to build large lng carriers, container ships 10,000 boxes a smooth delivery level; for the first time china started the construction of the first 3,000 meters deep water semi-submersible drilling platform; 160 000 / 200 thousand cubic meters of liquefied natural gas carrier-class, independent brands in the speed diesel engine and other key scientific research has made new progress. a domestic tool industry and the interactive development of shipbuilding industry should be said that the shipbuilding industry has made great achievements and the tool industry is closely related to sound and fast development in recent years, the two complement each other. 1. domestic tool industry processing support as “s that make s” of the industrial tools, domestic tool industry has for the shipbuilding industry enterprises, particularly the marine equipment manufacturers to provide the variety, technical precision, high-performance tool equipment, to enhance the overall capacity of shipbuilding industry and production efficiency to provide strong support. in the field of shipbuilding industry, the importance of marine diesel engine parts such as crankshaft, cylinder block, cylinder head, connecting rod and camshaft five major pieces of processing, a large marine propeller, rudder blade, rudder stock, cranes, anchor hinge separator ancillary products such as marine manufacturing, require various types of milling s and other tools. present, the chinese tool industry, shipbuilding industry has been able to meet most of the necessary tools, and rising high-tech equipment. among them, nc lathe , turning and milling centers, horizontal centers, vertical universal grinder, cnc milling and boring , gear hobbing and other equipment, local tool companies can provide. jinan tool group has successfully developed china’s first fully independent intellectual property-type five-axis cnc tools the equipment can improve the workpiece to be d surface accuracy and finish, reduce or even abolish the follow-up of hand-grinding, etc., apply to propeller processing. harbin measuring tools cutting tool group is china’s first success with the international advanced level sets of parallel s, this composed of tool production line can significantly reduce the number of units, to improve processing quality and reliability, suitable for large ship free surface complex parts. qi heavy cnc equipment co., ltd. independent development of “heavy-duty cnc center crankshaft tornado” to fill the gap. moreover, the first by the of large marine crankshaft root hercynian heavy industry co., ltd. in qingdao, offline, change made in china crankshaft of large tools rely on import of the situation. 2. shipbuilding demand driven same time, the shipping industry is the tool industry, the fastest-growing downstream industries, the most active industry, the relevant enterprises gantry milling and boring, boring and milling, machining centers, grinding s and gear cutting s great demand for large tools, quality and performance requirements are high, this fully stimulating the rapid development of domestic machine tool industry.
