英国的霍斯托曼凯奇公司董事、负责工程技术管理的经理Ray Butle,最近设计并试制成功了能使加工工件精密定位的新装置,该装置是由回转工作台、数字显示器以及操纵台组成的。在回转工作台上设置了精密光学角度器,变速箱,光栅发送器、转换器等,用闭环方式通过微处理机,把信号传送到驱动系统。并设置了键盘、纸带或磁性盒来存储程序的数据。这个存储器的容量能在很长的时间里存储许多程序。并且在必要的时候,还能对这些程序的数据进行编辑、删除,增补。由于使用了新研制的滚柱轴承和夹紧装置,因此,不管工作台在任何角度的位置,都能达到0.00025mm的最高定 Ray Butle, director of engineering and technology management at Horstorman Cage, a British based company, recently designed and prototyped a new device that allows precise positioning of the machined workpiece, consisting of a rotary table, a digital display and a console of. Set in the rotary table precision optical angle, gearbox, grating transmitter, converter, etc., with a closed-loop microprocessor through the way, the signal sent to the drive system. And set the keyboard, tape or magnetic box to store the program data. The capacity of this memory can store many programs for a long time. And when necessary, but also the data of these procedures to edit, delete, add. Thanks to the newly developed roller bearings and clamping devices, the highest setting of 0.00025 mm is achieved regardless of the table position at any angle
