A total of 11 servo axes machine with automatic tool change system, standard configuration the tool 42 can be expanded to a maximum of 92; Part docking in high-speed rotation. To illustrate the strategic value of this device, I have to say that of the world famous "Toshiba event. May 27, 1987, the Japanese National Police Agency arrested the Toshiba Machine Company of Japan Foundry Minister the Lung-two and the Vice Minister of the Machine Tool Division Tanimura Hiroaki. They were charged with direct responsibility for cases of high-tech products, Toshiba Machine Company Norway Constance Fort collusion, and the Former Soviet Union illegally export large milling. This is the world-famous Toshiba incident. Soviet hegemony when Soviet submarines because of the noise, NATO could certainty on their whereabouts, the competition has been at a disadvantage the submarine 90% of the noise from the propeller. The submarine noise increased by 10 dB, it will be 1 - to 3-fold increase in exposure distance; Conversely, the noise is reduced by 5 dB, its exposure distance will be reduced to 1/3 of the original. Underwater propulsion vortex to produce a small, low-noise, the other sonar is difficult to ascertain the advanced propeller, you need high-precision CNC machine tools. The United States and other Western countries, has been strictly prevent propeller blade machining high precision CNC machine tools into the Soviet Union (for example, in 1970 the Soviet Union had Western Order 6 units designed for submarine propulsion for shaping and polish with a giant milling, but later U.S. Navy blocked). The Soviet Union had to spend spy. Through the instigation of the Moscow office director of the trade shares of companies in Japan, and the light and the Itochu and Toshiba Machine Company of Japan, and Norway Constance Fort trading company personnel. From December 1982 to June 1983, the Soviet Union won the 9-axis CNC large marine propeller milling (machine about 10 meters high, 22 meters wide and weighs 250 tonnes of milling machine can process up to 130 tons, with a maximum diameter of 11 meters marine propeller, the error down to a hair's breadth below), and from the Toshiba Machine Company, a grinding machine and control research mushroom correction of computer software, used to improve the performance of the machine. 4-axis milling machine installed at the Baltic Shipyard in Leningrad City, 12 to 17 year manufacturing quality propeller. Manufacture of the aircraft carrier, "Kirov" class nuclear-powered cruisers and submarines propeller. Asked 10 years from 1975-1985, the former Soviet submarine noise reduction of 30 decibels. This apparent progress, so that people in the West were shocked. In 1986, the former Soviet Navy's new nuclear submarine equipment noise, only the equivalent of 10% of the previous nuclear submarines, the U.S. Navy until nearly 20 nautical miles, will it be possible to detect out. For example, in October 1986, 688 U.S. Navy nuclear submarine "Augusta" because no one is tracking Soviet submarine noise detected near in Gibraltar, even collided with. NATO and Japan and other 15 countries of the Paris Commission requirements: with a processing capacity of more than 3-axis CNC machine tools is a strategic material, strict export restrictions prohibit the export to communist countries. 5 heavy marine propellers processing machinery - heavy weapons CKX5680 seven Five Axis milling machine, which is the national "863 Program" project topics.

A total of 11 servo axes machine with automatic tool change system, standard configuration the tool 42 can be expanded to a maximum of 92; Part docking in high-speed rotation. To illustrate the strategic value of this device, I have to say that of the world famous "Toshiba event. May 27, 1987, the Japanese National Police Agency arrested the Toshiba Machine Company of Japan Foundry Minister the Lung-two and the Vice Minister of the Machine Tool Division Tanimura Hiroaki. They were charged with direct responsibility for cases of high-tech products, Toshiba Machine Company Norway Constance Fort collusion, and the Former Soviet Union illegally export large milling. This is the world-famous Toshiba incident. Soviet hegemony when Soviet submarines because of the noise, NATO could certainty on their whereabouts, the competition has been at a disadvantage the submarine 90% of the noise from the propeller. The submarine noise increased by 10 dB, it will be 1 - to 3-fold increase in exposure distance; Conversely, the noise is reduced by 5 dB, its exposure distance will be reduced to 1/3 of the original. Underwater propulsion vortex to produce a small, low-noise, the other sonar is difficult to ascertain the advanced propeller, you need high-precision CNC machine tools. The United States and other Western countries, has been strictly prevent propeller blade machining high precision CNC machine tools into the Soviet Union (for example, in 1970 the Soviet Union had Western Order 6 units designed for submarine propulsion for shaping and polish with a giant milling, but later U.S. Navy blocked). The Soviet Union had to spend spy. Through the instigation of the Moscow office director of the trade shares of companies in Japan, and the light and the Itochu and Toshiba Machine Company of Japan, and Norway Constance Fort trading company personnel. From December 1982 to June 1983, the Soviet Union won the 9-axis CNC large marine propeller milling (machine about 10 meters high, 22 meters wide and weighs 250 tonnes of milling machine can process up to 130 tons, with a maximum diameter of 11 meters marine propeller, the error down to a hair's breadth below), and from the Toshiba Machine Company, a grinding machine and control research mushroom correction of computer software, used to improve the performance of the machine. 4-axis milling machine installed at the Baltic Shipyard in Leningrad City, 12 to 17 year manufacturing quality propeller. Manufacture of the aircraft carrier, "Kirov" class nuclear-powered cruisers and submarines propeller. Asked 10 years from 1975-1985, the former Soviet submarine noise reduction of 30 decibels. This apparent progress, so that people in the West were shocked. In 1986, the former Soviet Navy's new nuclear submarine equipment noise, only the equivalent of 10% of the previous nuclear submarines, the U.S. Navy until nearly 20 nautical miles, will it be possible to detect out. For example, in October 1986, 688 U.S. Navy nuclear submarine "Augusta" because no one is tracking Soviet submarine noise detected near in Gibraltar, even collided with. NATO and Japan and other 15 countries of the Paris Commission requirements: with a processing capacity of more than 3-axis CNC machine tools is a strategic material, strict export restrictions prohibit the export to communist countries. 5 heavy marine propellers processing machinery - heavy weapons CKX5680 seven Five Axis milling machine, which is the national "863 Program" project topics.
