How to solve the problem of heavy load and high precision when the CNC cutting machine works

The work of CNC cutting machine is generally heavy-load and high-precision, which is characterized by the fact that the torque required to move the load is often far beyond the torque capacity of the servo motor itself, and the speed reducer is used to improve the output torque of the servo motor to deal with this problem.

1. Progressive torque:

The method of increasing the output torque may choose to directly increase the output torque of the servo motor, but this method requires the use of a high-power servo motor, and the increase in torque is proportional to the increase in the control current. The increase in the standards of electronic components and related electromechanical equipment will greatly increase the cost of the control system.

2. Increase the operating power:

Theoretically, the power of the stepper servo motor is also a method of increasing the output torque. The speed of the servo motor can be doubled to double the power density of the servo system, and there is no need to add standards for control system components such as drivers, that is, no It is necessary to increase the rated cost, and this needs to be achieved through the distribution of planetary reducers to achieve the purpose of increasing torque. Therefore, the development of high-power servo motors is to allocate the use of reducers. In this way, the situation of heavy load and high precision when the CNC cutting machine is working can be solved.
