摘要： In a thread grinder which grinds a thread grove on an inner surface of a workpiece while a rotation axis of a grinding wheel shaft is inclined with respect to an axis of a main shaft, a centering master which has a cylindrical outer surface is mounted to the main shaft. A measuring unit including two measuring instruments such that probes can contact two edges of a grinding wheel is mounted to the centering master. The origins of the measuring instruments are set by the probes contacting the cylindrical outer surface of the centering master. The measuring unit is moved in the axial direction of the centering master to bring the probes of the two measuring instruments into contact with the edges of the grinding wheel, respectively. The position of the grinding wheel shaft is adjusted such that measured values obtained by measuring instruments become same.
摘要翻译：在研磨轮轴的旋转轴相对于主轴的轴线倾斜的情况下，在工件的内表面上研磨螺纹槽的螺纹磨床中，具有圆筒形外表面的定中心主体安装在主轴。测量单元包括两个测量仪器，使得探头可以接触砂轮的两个边缘安装到定中心。测量仪器的起源是通过接触定心母盘的圆柱形外表面的探头来设定的。测量单元沿定心母盘的轴向移动，使两个测量仪器的探头分别与砂轮的边缘接触。调整砂轮轴的位置，使得通过测量仪器获得的测量值相同。

摘要： A quill includes a fixing side quill to be fixed to a spindle housing and a leading end side quill having a whetstone mounted thereon and removably connectable to the fixing side quill. In the connecting portions between the fixing side quill and the leading end side quill, faces that are perpendicular to the axis of the quill are combined with each other. A first drive shaft is provided within the fixing side quill, and a second drive shaft, rotatable integrally with the whetstone, is provided within the leading end side quill. The first drive shaft and second drive shaft are removably connected to each other.

摘要： A quill 2 includes a fixing side quill 11 to be fixed to a spindle housing 50 and a leading end side quill 20A-20C having a whetstone 40 mounted thereon and removably connectable to the fixing side quill 11. In the connecting portions between the fixing side quill 11 and the leading end side quill 20A-20C, faces C, C′ that are perpendicular to the axis T of the quill 2 are combined with each other. A first drive shaft 17 is provided within the fixing side quill 11, and a second drive shaft 27, rotatable integrally with the whetstone 40, is provided within the leading end side quill 20A-20C. The first drive shaft 17 and second drive shaft 27 are removably connected to each other.
摘要翻译：针筒2包括固定到主轴壳体50的固定侧针筒11和安装在其上的砂轮40的可拆卸地连接到固定侧针筒11的前端侧针筒20A-20C。在固定侧针筒11和前端侧针筒20A-20C，与羽毛笔2的轴线T垂直的面C，C'相互结合。第一驱动轴17设置在固定侧套筒11内，并且在前端侧针筒20A-20C内设置有与砂轮40一体旋转的第二驱动轴27。第一驱动轴17和第二驱动轴27彼此可拆卸地连接。
