XK5-15数控铣床的自动装卸刀机构(见图),是利用机床主轴自身的旋转来进行装刀和卸刀的一种机构。这种装置的优点,首先是装刀卸刀方便,节省装卸刀时间,减轻工人的劳动强度,提高劳动生产率,操作安全。用它装刀时,只要以较低的主轴速度开车正转,就可以上紧刀具。卸刀时,以主轴较低的速度开反车,就能松开刀具,然后停车取刀。整个装刀和卸刀过程,只需3～5分钟就可以完成。若是普通立铣,装卸刀一次,需20分钟左 XK5-15 CNC milling machine automatic loading and unloading knife mechanism (see photo), is the use of the rotation of the machine tool spindle to carry out the knife and unload a knife. The advantages of this device are firstly that it is convenient to load and unload knives, to save time for loading and unloading knives, to reduce the labor intensity of workers, to improve labor productivity and to operate safely. When using it to load a knife, you can tighten the tool as long as you drive it at a lower spindle speed. Unloading knife, the lower the spindle anti-car speed, you can release the tool, and then stop taking the knife. The entire process of loading and unloading knife, just 3 to 5 minutes to complete. If the ordinary milling, loading and unloading knife time, take 20 minutes left
