The CNC rotary table is usually a device used to process workpieces, and the rotor shaft is a component of the coupling. The relationship between them is mainly reflected in the following aspects:

1. Coupling connection: The CNC rotary table is usually connected to the motor or other transmission device through a coupling, and the rotor shaft is the part of the coupling that transmits the rotational force and torque. The coupling plays the role of connecting and transmitting the rotational force, enabling the CNC rotary table to receive the rotational power of the motor and transmit it to the workpiece.

2. Transmission performance of the rotor shaft: As the core part of the coupling, the rotor shaft has an important influence on the transmission performance of the CNC rotary table. The rotor shaft should have good rigidity and axial alignment performance, be able to withstand the torque and speed from the motor or other transmission devices, and stably transmit them to the CNC rotary table to ensure processing accuracy and efficiency.

3. Maintenance and care of the rotor shaft: During the use of the CNC turntable, the rotor shaft, as an important part of the coupling, needs regular maintenance and care. This includes lubrication, checking the bearing condition and fasteners, etc. to ensure the normal operation and life of the rotor shaft.

In summary, the CNC turntable and the rotor shaft are closely related. As the core transmission part of the coupling, the rotor shaft connects the motor or other transmission device and the CNC turntable, and plays the role of transmitting rotational force and torque. Reasonable selection and maintenance of the rotor shaft can ensure the normal operation and processing effect of the CNC turntable.

Rotor shaft alignment is an important task that has a significant impact on the normal operation and service life of the coupling. In the process of alignment adjustment, it is crucial to use accurate methods and tools. This article will introduce the requirements for the alignment adjustment of spacerless and spacer couplings, as well as the process and precautions of using laser alignment.

For the centering adjustment of the spacerless coupling, it is advisable to use the double gauge alignment method or the multi-gauge alignment method. The range and accuracy level of the gauge should meet the requirements of centering and alignment, and the rigidity of the gauge frame should also meet the requirements of the product technical documents. During the adjustment process, the two shafts should rotate synchronously, and the influence of axial movement should be taken into consideration.

The alignment adjustment of the coupling with a spacer shaft also needs to meet the requirements of no spacer. The alignment adjustment of the rotor shaft can be done by a single table alignment method. When calculating the adjustment amount, the influence of the alignment frame's own deflection on the table value needs to be considered.

Laser alignment is a common method for rotor shaft centering, concentricity measurement, and plane measurement. First, install stable laser generators, detectors, and other measurement system components, and preset the basic parameter settings of the input display according to the requirements of the machine technical documents. The three-point method (such as 0°, 90°, 270°) should be used for adjustment. If the rotor turning is restricted and cannot rotate 180°, the arbitrary three-point method can be used for alignment, and the shaft rotation angle is at least 2 20°. Before reading, a rough adjustment is required to make the laser beam completely penetrate the target area. During the adjustment process, adjust the vertical displacement first, then adjust the horizontal displacement, and ensure that the laser beam always fully penetrates the target area. In addition, it is also necessary to avoid the influence of changes in environmental factors on the alignment process.

By following the above requirements and steps, the rotor shaft alignment adjustment was successfully completed. The laser alignment method was used to ensure the accuracy and precision of the adjustment. The good alignment of the rotor shaft can improve the working efficiency and life of the coupling and ensure normal operation.

Through the introduction of this article, readers can understand the requirements of rotor shaft alignment and the process of using laser alignment. Following the correct methods and precautions can ensure accurate alignment and improve the working efficiency and life of the coupling.
