为期10年的日本“微型机械技术计划”今年进入第5个年头,日本在微型机械制造方面取得的成就引发了美国科学家对美日两国毫微技术不同发展方向的一番比较。 日本的毫微技术注重于机械制造。由日本政府部门组织26家大公司参加、为期10年的“微型机械技术计划”总预算近2.5亿美元,制订了三大应用目标,即制造出能进入管道内检修工业管道的微型机械;能进入病人血管实施手术的微型机器人,能生产微型机械零部件的低能耗微型工厂,该工厂本身面积将不超过数平方米,其主要产品将是手表、相机等设备中的微型部件和其他微型机械的零部件。 如今该计划时间过半,日本取得的成绩令世人瞩目。如丰田公司制作的微型汽车只有米粒大小,却有发动机、轮胎、车轴、顶灯、前灯等24个部件,而且该车可以每秒5厘米的速度行驶,精工公司制作的微型钻可在金属上打出直径小于1毫米的圆孔;奥林帕斯公司正在试验的温控变形金属技术
The 10-year “Micromechanical Technology Project” in Japan entered its fifth year this year. The achievements made by Japan in the field of micromechanical manufacturing sparked a comparison between U.S. scientists in different development directions of nanotechnology in the United States and Japan. Japanese nanotechnology focuses on machine building. By the Japanese government departments to organize 26 large companies to participate in a 10-year “micro-mechanical technology program,” the total budget of nearly 250 million US dollars, formulated the three major application goals, that is, to create access to the pipelines to repair industrial pipelines of micro-machinery; Micro-robots that enter the patient’s blood vessels for surgery, low-power miniature plants that produce micromachine components that will themselves cover an area of less than a few square meters, and whose main products will be micro-components in watches, cameras and other micro-machines Parts. Now more than half of the plan, Japan’s achievements have attracted worldwide attention. Such as Toyota mini-cars produced only grain size, but there are engine, tires, axles, dome lights, headlights and other 24 components, and the car can be 5 cm per second speed, Seiko Micro drill produced in the metal Hit a diameter of less than 1 mm round hole; Olympus is testing the temperature control deformation metal technology
