Difference:
The motorized spindle is generally used on CNC machinery, while the mechanical spindle is used on general machine tools.
Reason: Low cost lathe can not use motorized spindle, because the cost is too high. And the high-end lathe, because the demand spindle precision is high, the electric main shaft with large calorific value is very simple to form thermal deformation, and then form the spindle box height change, so it is not suitable for use on high precision lathe.
Explanation:
Spindle is a new technology which combines spindle and spindle motor in the field of NC machine tool in recent years. The main drive system of high speed CNC machine tool cancels the belt wheel drive and the gear drive. The spindle of the machine tool is driven directly by the mounted motor, thus shortening the length of the main drive chain of the machine tool to zero, realizing the “zero drive” of the machine tool.
Mechanical spindle refers to the shaft that drives the workpiece or tool rotation on the machine tool. usually consists of spindle parts, bearings and transmission parts (gears or belt wheels) etc. In the machine is mainly used to support the transmission parts such as gear, belt wheel, transmission of motion and torque, such as machine spindle; some are used to clip the workpiece, such as mandrel.
