Small CNC vertical latheExcellent processing flexibility, high adjustment, high processing accuracy. Today's small CNC vertical lathe growth target is the purpose of high-speed CNC lathe processing, to achieve high speed efficiency. 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 to the impact of small CNC vertical lathe speed on processing.

The influence of the speed of the small CNC vertical lathe on the processing:

The spindle speed has a significant impact on the machining process when using a small CNC vertical lathe for metal cutting. 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 in excess of the specified value or at a higher spindle speed will cause an increase in the cutting temperature of the small CNC vertical lathe. 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. When the small CNC vertical lathe is cutting the large diameter of the workpiece, the spindle speed is low; when the small diameter of the workpiece is cut, 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.
