Slowly move the container so that spindle is roughly in the center of the container and away from its point of entry into the coating sample.
缓慢地移去容器这样锭子大概处于容器的中心并且从进口到涂层的样品上。
This function can make numerical control system according to the point in the X coordinates, as the diameter of the workpiece calculated value spindle speed, and the cutting speed to be constant.
该功能可以使数控系统根据刀尖所处的X坐标值,作为工件的直径值来计算主轴转速,使切削速度保持恒定。
The experiments to verify the limit cutting depth show that the cutting efficiency of machine tool can be improved by cutting at the spindle speed corresponding to the stable cutting point.
极限切深试验表明,以稳定切削点所对应的主轴转速进行切削可以提高机床的切削效率。
