Germany has been the world engine bed technological advance, the machine tool industry developed country. Its engine bed production is later than for 50 years the US, but because the personnel quality is high, processes the craft, the thorough engine bed to experiment as well as dares to innovate familiar, its engine bed technology surpasses France, Britain successively, also has caught up with the US, and realized the engine bed export amount in 1969 to occupy the world first. in 1976, Germany’s engine bed output value surpassed the US, leapt to the world leader. The German present population is 83,000,000 people, the machine tool industry jobholders approximately 70,000, has 300 enterprises. in 2000 engine bed output value 7,330,000,000 US dollars, export amount 3,890,000,000 US dollars, occupied second in the world.

The German government takes the machine tool industry all along strategic status The German government takes the expand industry, but the expand industry needs to equip, therefore takes the machine tool industry specially the development, thought that the machine tool industry is in the entire machine manufacturing industry is most important, is most active, most has the creativity the department. Started when the 19th century constructed the railroad, French government’s policy buys the engine bed, but The German government’s policy was makes the engine bed. They studied at that time UK and US’s advanced engine bed technology, and first built the engine bed test chamber in the world, carried on the comparative trial unceasingly, improved. They also send the technical personnel, the worker study abroad. Therefore, its engine bed production and the machine tool construction technology advancement is very quick. For development mining, the power, the shipbuilding industry, Germany gradually has also established some Heavy machine-tool plants, becomes heavy-duty machine tool’s production base. In the world many biggest heavy-duty machine tools, like the processing work piece diameter is 6 meters lathes, 12 meters gear-hobbing machines, the work table 5×29 rice Dragon Gate engine bed, the processing diameter is 25 meters vertical lathes and so on, is Germany makes. Because the quality is good, the precision is high, the moderate cost, causes the heavy-duty machine tool which, the large-scale precision machine tool and many NC heavy-duty machine tools Germany produces (for example slideway grinder and so on) internationally very much has the market. After Second World War, The German government strengthens the machine tool industry by might and main the development, if works out the engine bed curacy standard, the renewal product mix, unifies the traditional technology and the modern electron, develops each kind of NC engine bed, snatches world market which loses.

The main engine design is exquisite, with main engine necessary foundation spare part, cutting tool, NC system advanced Germany casts the forging precision to be high, the quality is good, ratio of the metal-cutting machine tool and the formed engine bed is 2:1. In the metal-cutting machine tool capacity and the output, the rough machining engine bed are few, the precision work grinder are many. They take the cutting tool, grinding wheel’s sophistication, to enable the engine bed specially high grade to display the performance and the efficiency fully. In the main engine design, the technology is exquisite, the structural change are many, each kind of engine bed from becomes the complete series, the metal-cutting machine tool and forms engine bed’s variety above 4000 kinds, each kind of gear engine bed, the cutter grinder variety is specially more complete.
