美国诺尔弗克和西方铁路朴茨茅斯车轮工厂的计算机控制的车轮车床深受人们的注意。这是因为该机床可使货车磨损车轮的重旋自动化。轮对旋转一周,电子探头即可测出为重旋车轮所需的各项数据。数据立即输入控制机床操作的专厢计算机内。当使轮对旋转时,几秒钟内就可对每个车轮开始切削程序。该机床可供窄轮和宽轮的重旋之用。车轮上最大的圆弧半径(最大允许到1.58 The computer-controlled wheel lathe of Northropark and Westport Portsmouth Wheel Factories has drawn much attention. This is because the machine can automatize the wagons of the wagon wheels. Rotation of the wheel a week, the electronic probe can be measured as the re-spin all the necessary data wheel. The data is immediately entered into the box computer controlling the operation of the machine. When the wheelset is rotated, the cutting program can be started on each wheel in seconds. This machine is available for heavy and wide wheels. The largest radius of the wheel (maximum allowable to 1.58
