difference:

Electric spindles are commonly used in CNC machine tools, while mechanical spindles are used in general-purpose machine tools.

Reason: Due to high costs, low-cost lathes cannot use electric spindles. On high-end lathes, due to the high precision required for the spindle, the high heat generating electric spindle simply forms thermal deformation, and then the height of the spindle box changes, making it unsuitable for high-precision lathes.

Instructions:

Electric spindle is a new technology that combines machine tool spindle and spindle motor in the field of CNC machine tools in recent years. The main drive system of high-speed CNC machine tools has removed belt transmission and gear transmission. The spindle of the machine tool is directly driven by a built-in motor, which shortens the length of the main transmission chain of the machine tool to zero, achieving "zero transmission" of the machine tool.

Mechanical spindle refers to the axis on a machine tool that drives the rotation of workpieces or cutting tools. The spindle components are usually composed of spindle bearings and transmission components (gears or pulleys). This machine is mainly used to support transmission components such as gears, pulleys, drive motion and torque, such as machine tool spindles; Some are used to clamp workpieces, such as spindles.
