Recently, when Governor Carey came to New York to encourage Japanese companies to invest, one of the few factories he attended was the big uma machinery factory. Okuma already has a wholly owned subsidiary in N Farmingdale, mainly the sales and distribution office. Y. First US action against Nagoya Based on machine tool manufacturers. Like some other Japanese machine tool companies, Okuma is starting to do business in the US to help avoid possible trade friction, just as Japanese automakers are now facing friction in exports to the US. Simply put, machine tools are machines that make parts for other machines. They make up billions of dollars in the U. Operating equipment, computers with complex shapes and flat metals- Linkage System for manufacturing robots. Half of the ads More than a dozen machine tool manufacturers opening factories in the United States are one of Japan\'s most advanced Ikebukuro ironmaking plants. Ikegai opened its first US factory in Long Beach, California. Earlier last year, it shared production With Strasman machinery. The factory now assembles five tank bags FX20 CNC machine tools per month, a widely used CNC lathe. ( Nearly 75% of Japan\'s new products have CNC equipment installed on machine tools to automate through various electronic systems. ) High quality customers of Japanese machine tool products provide manufacturers with high quality and reliable machine tools. One advantage they seem to have over American competitors is that their delivery time is shorter Seven months, according to an estimate, compared to 18 months for many American manufacturers. As aso Asano, president of American subsidiary Ikebukuro, said: \"We have no problems in the United States. S. Sometimes the problem is that the machine is done too fast. About 40% of Japanese machines Tool production is shipped abroad every year, and the United States is the largest overseas market for Japanese products. In addition to the direct investment of Japanese companies, the Japanese government hopes to prevent trade troubles by authorizing a machine tool cartel, which will maintain the lowest export price for two major categories of machine tools. The agreement also applies to the EC, which is \"to avoid excessive competition in export prices for these two product lines and to avoid unfair trade such as dumping, ikusaburo Kashima of the Ministry of International Trade and Industry, the government agency responsible for implementing cartel provisions, explained.

Growth in the industry has been spurred by strong demand from aircraft and electronics industries around the world, as well as from the Japanese automotive industry, which set a record in production and sales in 1980. Detroit automakers are expected to spend up to $80 billion in a decade to build smaller fuels. Efficient cars will also be stable customers of machine tools. According to the Japan Association of machine tool manufacturers, 350 to 400 companies produce machine tools. However, only 68 of them accounted for 3- Hatoshi Hakojima, the association\'s manager, said four of all products last year. Official data from the Japanese government show that machine tool production in the first 10 months of 1980 was $2. 7 billion, plus $1. Exports of 1 billion. Less than 40% of products are exported to the United States. Initial estimates for the year were $3. $3 billion, up from the previous record of $2 in 1979. 4 billion. \"We have a very good, very manageable situation,\" he said . \"Hakojima. Japanese machine tool manufacturers overstocked orders for two years at peak times. Last November, it\'s still a 14- Month backlog, compared to six or seven months in the United StatesS. According to official estimates of the association, Japanese companies last year\'s new orders totaled about $4 billion. In Japan, about 30% of production went to the automotive industry, 30% to the general machinery industry, and the rest were mainly exported to the United States, Western Europe, South Korea and Southeast Asia. At the ikebukuraki plant outside Tokyo, workers repeatedly tested new machines to ensure that performance was as accurate as possible. Machine- The tool buyer wearing a white lab coat was invited to the factory to observe and participate in the test. \"Our customer needs cover a wide range, so our factory\'s goal is to make machines as accurately as possible,\" said Akio Kira, plant manager . \". \'\'One khaki- The dressed worker tested a CNC lathe to monitor how true it was to shave off the metal rods used on the escalator on a cloudy green screen. A series of red numbers flashed through the screen, showing that the machine had ground the rod to within six microns of its specifications. Micron is one in a million of 1 m. This precision will be essential in the new generation of machine tools, which will be mainly used in high-tech fields such as industrial robots, aerospace, Nuclear Instruments and marine exploration. Software - Machine programming for this advanced task- Industry experts say it will become more and more important.
