In high-speed cutting, the machining accuracy, cutting life and productivity are influenced by the high rotational speed of spindle.

高速切削时主轴转速很高，加工精度、刀具寿命和生产率受到影响。

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。

Select a combination of spindle and speed that gives a minimum scale reading of 10 and preferably in the middle or upper portion of the scale.

选择锭子和速度的综合指数，它给于最小的刻度10和最合适的是在刻盘的顶部和中部。
