CNC vertical lathes are often used to produce high-precision parts. In the process of CNC vertical lathe processing high-precision parts, the quality and performance of the spindle are particularly important. Therefore, let’s take a look at the spindle requirements of CNC vertical lathes.
First of all, CNC vertical lathes have very low requirements for the axial and radial runout of the spindle. Axial and radial runout refer to the deviation of the spindle during rotation. If this value is too large, the part will lose accuracy. The accuracy of parts required for CNC vertical lathes is usually within tens of microns, so the axial and radial runout of the spindle cannot exceed a few microns.
Secondly, CNC vertical lathes have very high requirements on the roundness, parallelism and verticality of the spindle. The roundness of the spindle refers to the degree to which the spindle rotates into a circle, and the parallelism and perpendicularity refer to the degree of parallelism and perpendicularity between the axis of the spindle and the guide rail. These three indicators are key factors to ensure the processing accuracy of machine tools and parts.
In addition, CNC vertical lathes also have certain requirements for the spindle speed, torque and stiffness. The high-speed spindle can improve processing efficiency, and sufficient torque and stiffness can ensure that the machine tool can maintain stable operation under heavy load.
Finally, CNC vertical lathes also have certain requirements for the spindle tool change system. Usually CNC vertical lathes are equipped with automatic tool changing systems to facilitate processing of different parts. As the number of workpieces increases and the complexity of processing increases, the reliability and stability of the spindle tool change system become increasingly important.
To sum up, CNC vertical lathes have very high requirements for the spindle, because the quality and performance of the spindle directly affect the accuracy and quality of the processed parts. Therefore, when applying CNC vertical lathes, we need to add high-standard spindle equipment to ensure processing quality and efficiency.
