CNC vertical lathe_Small CNC vertical latheExcellent processing flexibility, high adjustment, high processing accuracy. TodaySmall CNC vertical latheThe purpose of the growth target is high-speed CNC lathe processing to achieve efficiency at high speed. However, once the small CNC vertical lathe exceeds the specified speed of the machine tool spindle, the original existence of some small problems, sometimes become a serious problem. The following is a brief introduction for everyoneSmall CNC vertical latheThe influence of speed on processing.
CNC vertical lathe_Small CNC vertical lathethe impact of speed on processing:
UseSmall CNC vertical latheIn metal cutting, the spindle speed has a significant impact on the machining process. In the low speed or common speed range of the spindle, it has little effect on the processing quality. Between the cutting speed and the processing quality, the selection of various cutting parameters will follow the laws revealed by the cutting theory. Machining above the specified value or at a higher spindle speed will causeSmall CNC vertical latheThe increase in cutting temperature. The greater centrifugal force of the workpiece may also cause vibration of the machine tool. The higher the spindle speed, the greater the force (centrifugal force) that pulls the part outward from the rotating shaft. Especially in finishing, the centrifugal force has a greater impact on the spindle bearing.
Small CNC vertical latheThe cutting speed is a fixed value to ensure the accuracy of the machined parts. Control the machine tool spindle speed, through the control system in the command, to achieve a constant cutting speed. When machining parts, when the peripheral cutting speed is constant, the roughness of the workpiece surface after turning can be kept consistent, and the service life of the parts can be improved. After setting a constant cutting speed, the rotational speed of the spindle is varied at different diameters of the workpiece.Small CNC vertical latheAt the large diameter of the cutting workpiece, the spindle speed is low; at the small diameter of the cutting workpiece, the spindle speed is high. If the spindle speed is too high, the workpiece will fly out of the danger, so the need to constrain the spindle speed.
