German economy and its products are associated with supposedly German characteristics such as high precision,quality and reliability.The sector produces a large variety of equipment and machines(i.e.capital goods)to be used in the,新机电英语 课文讲解,Unit 1,production processes of other industries.Some of the most important branches of mechanical engineering are machine tools(including manufacturing systems),printing and paper machines,power transmission engineering,equipment for air handling,refrigeration and air pollution control,vacuum and compressor technologies and food processing and packaging machines.These branches account for half of the total production value of the,新机电英语 课文讲解,Unit 1,German machinery industry.German machines are well-known for their high degree of specialization and customization.They are typically produced in small batches whereas Japanese producers concentrate on multipurpose,standardized machines which can be produced in larger production runs.In the 1970s,German machine tool producers were challenged by new Japanese competitors that offered inexpensive,multi-purpose machinery,新机电英语 课文讲解,Unit 1,with a high degree of technological sophistication and flexibility i.e.numerically controlled(NC)machines.In 1980s,Japanese machinery producers were faster in integrating microelectronics applications into their products puterized NC machines(CNC),robots.,新机电英语 课文讲解,Unit 1,The Germany machinery industry has a long tradition of exporting its products to other countries.The important producers are often among the world leaders in
