Application of Planetary Reducer in CNC Machine Tool Industry

It is well known that the transmission sources of CNC machine tools are all servo electric motors. With the progress of industry, electric motors have been innovating in the direction of precision, high efficiency, simple control and so on. Mechanical matching has also advanced from traditional screw to precision ball screw. However, due to the machining of the machine tool itself, the conditions of the load feed system are quite different. It is necessary to add a reducer to increase the torque, improve the inertia matching at the load end, and make the feed operation smooth. Ordinary gear reducers have poor efficiency, large volume, short service life, and cannot be used for precise positioning control. Therefore, the use of high-precision planetary gear reducers with low backlash is still the best combination, which can eliminate the difficulties mentioned above.

Most of the planetary gear reducers with high precision and low backlash are used in the feed device. Because this type of gear reducer can withstand high input speed, it produces high torque density, high strength torsional rigidity, low backlash, low noise value, and easy installation. It is suitable for any assembly direction. The reduction ratio is sufficient and complete, so that the menu of the CNC machine tool now enters a more stable and precise state.
