Shanghai imported motorized spindle maintenance manufacturer believes that motorized spindles are usually integrated with the machine tool and installed inside the machine. During installation, it only needs to be placed in the special position of the machine spindle, which is very convenient and simple. Because the motorized spindle is installed inside the machine, space can be effectively saved and no special installation space is needed.

The manufacturer believes that compared with other machine tools, machines equipped with motorized spindles have a longer service life at the same speed: the spindle is powered directly by its internal motor, and there is no need to connect other transmission gear belts or devices when in use, effectively improving the working efficiency of the spindle and thus the performance of the machine. Moreover, because the spindle is electrically driven, it can also reduce the vibration frequency caused by machine running, effectively reducing the noise produced by transmission belts or gears. The motorized spindle has strong damping, so it can greatly improve the machining efficiency and quality of the machine tool, thereby extending the machine service life and reducing machining cost.

Currently, machines using motorized spindles do not need to change machines according to different workpieces; only the output power of the spindle needs to be set to better adapt to different working conditions and loads.

The manufacturer believes the reasons affecting the rotation precision of motorized spindles:

1. Spindle errors. Mainly including roundness errors, spindle journal coaxiality errors (causing spindle axis offset) and perpendicularity errors between the spindle journal axial bearing surface and the axis (affecting spindle axial displacement).

2. Bearing errors. Bearing errors include roundness errors of sliding bearing bores or rolling bearing raceways, waviness of sliding bearing bores or rolling bearing raceways, shape and size errors of rolling bearing rollers, perpendicularity errors between the bearing locating end face and the axis, parallelism errors between bearing end faces, bearing clearance and stress deformation during cutting, etc.

3. Unequal radial stiffness and thermal deformation of the spindle system. The main causes affecting spindle rotation precision are bearing wear and wear of shaft and contact surfaces. To ensure the spindle works normally with precision, the wear rate of bearing-related parts should be reduced as much as possible; the main way to reduce wear is lubrication. Therefore, choosing a reasonable and correct lubrication method is an important condition for ensuring the normal operation of the motorized spindle.
