How much do you know about the shaft of roller?

The machining quality of the shaft is another important factor affecting the quality of the roller. Its own roundness will directly affect the radial runout and rotational resistance of the roller, which will ultimately affect the running life of the roller. Therefore, we use the thimble at both ends of the shaft to process the cutting method one by one and use the grinding to ensure the size and accuracy of the shaft, thus avoiding the quality problems caused by the difference of the shaft.
