Application Case of Planetary Reducer in CNC Machine Tools

- Aug 17, 2019-

The drive source of CNC machine tools comes from the servo electric motor. With the advancement of industry, electric motors have also been moving towards precision, efficiency, control and innovation. The mechanical matching has also progressed from the conventional screw to the precision ball screw. However, due to the machining of the machine itself, the conditions of the load feed system are quite different. It is necessary to add a reducer to increase the torque, improve the load inertia matching, and make the feed run smoothly. The ordinary reducer has poor efficiency, large volume, short life, and can not be used for precise positioning control. Therefore, the use of high-precision low backlash planetary gear reducer is still the best match, which can eliminate the above difficulties.

CNC machine tools use G+ high precision low backlash planetary gear reducer

Most of the high-precision and low-backlash planetary gear reducers are used in the feed device. Because this type of reducer can withstand high input speed, it produces high torque density, high strength torsional rigidity, low backlash and low noise. Easy to install, suitable for any assembly direction, the reduction ratio is sufficient and complete, so that the menu of CNC machine tools is now entering a more stable and precise realm.

Advantages of high precision low backlash planetary gear reducer

Compact, small, and rigid, it produces high torque density, and coaxial input and output make the design more flexible and lightweight. More than 96% high transmission efficiency, maintenance-free, long life, modular design and installation and easy to install, both forward and reverse can be applied, good thermal conductivity, not easy to temperature rise, so it is the best choice for CNC machine tools.

Applications

1. At least four or more machining centers and CNC milling machines can be used.

X, Y axis feed and rapid feed can increase feed smoothness, reduce noise and reduce the cost of servo motors. Because of the high torque, the control is easier, although the load is different, it does not affect the feed smoothing. The load on the Z-axis is completely different due to the gravity of the gravity. The installation of a high-precision, low-backlash planetary gear reducer can reduce the load on the servo motor and increase the life of the machine. The tool changer requires fast, accurate positioning and low vibration. The high precision low backlash planetary gear reducer is still the best choice.

2. At least three or more CNC lathes and turning centers can be used.

X, Z axis feed and rapid feed, fast and smooth. High-precision, low-backlash planetary gear reducers are used with precision ball screws to reduce mechanical failure rates and improve precision. The servo control high and low file conversion device shortens the time and the transfer is fast and stable.

3. At least three or more digital grinding machines and electric discharge machines can be used.

The three axes of X, Y and Z are smooth and smooth, which makes the parameter setting of the controller simpler, so that the finished product is highly precise, the arc joint is smooth, and the surface roughness is reduced.

Some points in the practical application

Thanks to the high precision, low backlash and precision ball screw, the control system is easy to set up and can produce high precision products. The high-strength and rigid structure has long service life, high efficiency, maintenance-free oil change, etc., which reduces mechanical failure. Since the gears are subjected to ion nitriding treatment, the surface magnetic layer is wear resistant and the substrate maintains its toughness. Hard cutting method, with fewer variants and correct tooth type, can produce high precision low backlash planetary gear reducer.
