Electric Spindle Shaft is more compact than Mechanical Spindle Shaft, modular structure, easy to install. However, Electric Spindle Shaft is more prone to vibration than traditional timing belts and V-belt spindles. After all, traditional spindles can eliminate the vibration of the motor through the flexible belt. Furthermore, the Electric Spindle Shaft generates more heat. The heat dissipation requirements are higher than traditional ones.

Electric Spindle Shaft is generally used on CNC machinery, while Mechanical Spindle Shaft is used on general machine tools.

Reason: Low-cost lathes cannot use Electric Spindle Shaft, because it will cause too much investment, while high-end lathes require higher accuracy of Electric Spindle Shaft and Electric Spindle Shaft with large heat generation. It is easy to form thermal deformation and then form a headstock. The height changes, so it is not suitable for use on high-precision lathes.

Electric Spindle Shaft is a new technology that integrates machine tool spindles and spindle motors in the field of CNC machine tools in recent years. The main drive system of the high-speed CNC machine tool cancels the pulley drive and gear drive. The main shaft of the machine tool is directly driven by the built-in motor, thus shortening the length of the main transmission chain of the machine tool to zero, realizing the "zero transmission" of the machine tool. Mechanical Spindle Shaft refers to the axis that drives the workpiece or tool to rotate on the machine tool. The main shaft components are usually composed of the main shaft, bearings and transmission parts (gears or pulleys). In the machine, it is mainly used to support transmission parts such as gears and pulleys to transmit motion and torque, such as machine tool spindles; some are used to clamp workpieces, such as spindles.
