    • PROBLEM TO BE SOLVED: To provide a boring tool which not only is lightweight but also has both abrasion resistance and high stiffness. SOLUTION: In the boring tool, a shaft-like tool body 10 is provided with a cutting tool 20 and the tool body 10 reciprocates in the axial direction to ream a hole provided to a workpiece. The tool body 10 includes a base material 11 formed by a carbon fiber reinforced composite material, a hard plating layer 13 consisting of hard plating applied to a surface 10b of the tool body 10, and an under layer 12 which is applied between the base material 11 and the hard plating layer 13 and which consists of base plating to improve the wettability of the hard plating layer 13.

    • A line boring apparatus comprising a motorized spindle and tool support mounted on a support frame for motion along two axes perpendicular to a rotational spindle axis. The spindle is also supported for motion along the spindle axis relative to the tool support. A tool cradle is supported beneath the spindle on the support frame and stores boring bars of differing outside diameters equipped with support bushings having outside diameters equal to an inner diameter of the tool support. A CNC is programmed to actuate an axes drive to cause the spindle to select a boring bar and bushing from the cradle. The CNC and axes drive then move the bar and bushing to a predetermined boring position axially aligned with an interrupted line bore to be machined in a workpiece. The CNC then commands the spindle to advance axially toward the tool support, removably engaging the bushing in the tool support and continuing to push the boring bar through the engaged bushing while rotating the bar and boring the interrupted line bore in the workpiece.
    • 一种线镗孔装置,包括安装在支撑框架上的电动主轴和工具支架,用于沿垂直于旋转主轴轴线的两个轴线运动。 主轴也被支撑用于沿着主轴轴线相对于工具支撑件的运动。 工具支架支撑在支撑架上的主轴下方,并且存储具有不同外径的镗杆,其具有外径等于工具支撑件内径的支撑衬套。 CNC被编程为启动轴驱动器,使主轴从支架中选择一个镗杆和衬套。 然后CNC和轴驱动器将杆和衬套移动到与被加工成工件的中断的线孔轴向对准的预定的镗孔位置。 CNC然后命令主轴轴向前进到工具支撑件,可拆卸地接合工具支撑件中的衬套,并且继续将镗杆推动通过接合的衬套,同时旋转杆并钻削工件中的中断的线孔。
