Here are our sales catalog and instruction manualsSection V Broaden Your HorizonGet to know more of the World Famous Companies.FANUC CORPORATIONFANUC's businesses were founded in 1956 when it started to develop numerical controls (NCs) and servo systems. Since its founding, FANUC has always emphasized research and development in its management. In 1956, the first NC in Japanese private sector was developed successfully. Since then, FANUC have continued to develop new technology into their products.FANUC LTD was established in July 1972 when the Computing Control Division became independent from FUJITSU.The history of FANUC has been recognized the history of CNC itself. With a land of approximately 1.2 million square meters, FANUC headquarters is located at the foot of Mt. Fuji, near Lake Yamanaka, in a wonderful natural environment surrounded with highland woods. Here, FANUC has situated laboratories such as CNC Laboratory, Software Laboratory, Software Development Center, Servo Laboratory, Robot Laboratory, Robot Technology Center, Robomachine Laboratory, Laser Laboratory and Basic Laboratory, as well as the Central Technical, the FANUC Training Center and various social and recreational facilities. Also settled here are factories such as the Electronics Factory, Servo Motor Factory, Machining (Turning) Factory, Press & Die Cast Factory, Machining (Milling) Factories, Sheet Metal Factory, Robot Factory, Injection Molding Machine Factory and Laser Factory.FANUC main building office sections as well as all its laboratories and factories are highly automated to achieve efficient management.编制日期：20＿＿年＿＿月＿＿日教师签字：教研室主任签字：数控技术英语专业授课计划20______－20______ 学年第______ 学期_______ 系（部）专业班授课时间：第周第1－4 课时文章及题目:Unit 2 Introduction of Computerized Numerical Control教学目的：1.
