本小型磨刀机操作简易，性能稳定。砂轮由电动机带动，电动机和砂轮部分固定在双坐标工作台上，可以在XY轴方向移动。刀具装夹在三向虎钳上，虎钳可以在XYZ三个方向转动，通过两者的移动和转动，便可精确地刃磨出刀具所需要的角度。

Design of Small-scale Grinding
ABSTRACT
This paper is the design of a small grinders. Mainly calculate and design on the table, three grinders, pulleys, and to the jaw vice spindle and V belt. This small grinders is simple operation, stable performance. Grinding wheel is driving by moter, motor and grinding wheel part fixed on double coordinates working place, it can move in the direction of XY axis. The tool clamping in three to the jaw vice, jaw vice rotating in three directions, XYZ. Through both mobile and rotation, the small grinders can precisely cutting out the tools needed angle
