The voltage across the motor multiplied by the current flowing through the motor does not equal the output power. Output power is the power value at which the motor converts electrical energy into mechanical energy. Since electric motors cannot completely convert electrical energy into mechanical energy, due to the actual coil resistance,

The small production machine tools referred to here include miniaturized CNC lathes, CNC milling machines, machining centers, engraving machines and ordinary lathes, milling machines and compound machine tools, etc.

The voltage fluctuation of the power grid should be controlled between +10% and -15%, while the power supply fluctuations in our country are large and the quality is poor. It also hides such disturbances as high-frequency pulses, plus human factors (such as sudden power failure) Wait).

The tool centralized division method is to divide the process according to the used tool, and use the same tool to finish all the parts that can be completed on the part. Use the second knife and the third to complete other parts that they can complete.

Numerical Control Machine Tools (referred to as Numerical Control Machines) is a control technology that applies digital computing technology to machine tools. It expresses various control information in the machining process with coded numbers and inputs the numerical control device through the information carrier.
