inery Compared with Japanese and West German producers, .. gear producers have much lower percentage of gear-making machine tools that are less than 1 years old. The following tabulation compares the share of gear cutting anu finishing machine tools by age for the United States and Japan (in percent): 6 Age Country/survey year United States 1 Japan 1 0 to 4 years 4.6 1.9 5 to 9 years 7.1 2 .6 over 1 years 8.3 6.5 e3 Based on data from Ministry of International Trade and Industry' (MM') statistical survey of Japan' machine tool inventory undertaken in September 1, and summarized in 'Trends in Machine Tool Inventory Over Past Seven Surveys,' Metalworking Engineering and Marketing, November 1, pp. 1-1. According to officials of VDMA, it is not the average age of the total machinery that is important, "but the age of the key machinery in gear manufacturing - cutting, grinding, milling machinery; measurement devices, heat treatment equipment." 6 The VDMA estimates that the average age of these key machines in the West German gear industry is less than 1 years old. Key gear-making machinery in Korea and Taiwan is much newer than that in the United States. In Taiwan, most machinery is less than 1 years old 6s and in Korea, less than 4 years old. 6 Investment by .. and French gear producers is not as great as that of West Germany or Italy. Gear producers tend to use older machines for dedicated operations, thereby reducing the need for substantial new investment. However, new machines are used as much as possible in order to maximize the return on investment. 6 " VDMA written response to USITC staff questions, Dec. 1, 1, . 3. 6 American Institute in Taiwan Airgram, 1, Taipei, Message Reference No. 0.
