苏联明斯克分院研制成功一种内圆 磨床的防护装置,无论砂轮靠近工件还 是返回原位或者是修整砂轮时,它总是 跟着砂轮,保证了砂轮工作的安全。 该装置(如图所示)防护罩2固定 在圆杆5的前端并护盖着砂轮;在圆杆 的槽里装有滚动轴承6(在垂直和水平 面内),圆杆依靠它沿导轨7移动。 Minsk Branch of the Soviet Union succeeded in developing a protective device for the internal grinder, whether the wheel near the workpiece or return to its original position or dressing wheel, it always follows the wheel, to ensure the safety of the work of the wheel. The device (as shown) is attached to the front end of the rod 5 and covered with a grinding wheel; in the groove of the rod is mounted a rolling bearing 6 (in the vertical and horizontal planes) by which the rod moves along the guide rail 7 .
