The transmission source of CNC machine tools comes from servo electric motor. With the progress of industry, electric motors have also been moving towards precision, high efficiency, simple control and innovation.
The mechanical matching has also progressed from the traditional screw to the precision ball screw, but due to the machining of the machine tool, 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 difficulties mentioned above.
CNC machine tools use high precision low backlash planetary gear reducer
Most of the high-precision low backlash planetary gear reducers are used in the feeding device. Because this type of reducer can withstand high input speeds, it produces high torque density, high strength torsional rigidity, low backlash, and low noise values. 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 more precise realm.
Advantages of high precision low backlash planetary gear reducer
Compact structure, small size, strong rigidity, can produce high torque density, coaxial input and output make the design more flexible and light. High transmission efficiency above 96 ﹪, maintenance-free, long life, modular design, easy application and installation, both forward and reverse are applicable, good thermal conductivity, not easy to rise in temperature, so it is the best component for CNC machine tools.
1.At least four machining centers and CNC milling machines can be used.
X and Y axis feed and rapid feed can increase the smooth feed, reduce noise, and reduce the cost of the servo motor. The high torque makes the control easier. Although the load is different, it does not affect its feed smoothness. The load of the Z-axis is totally different due to 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 changing mechanism requires fast speed, precise positioning, and low vibration. High precision and low backlash planetary gear reducer is still the best choice.
2.CNC lathes and turning centers can use at least three.
X, Z axis feed and rapid feed, fast and smooth. High precision low backlash planetary gear reducer is used with precision ball screw to reduce mechanical failure rate and improve precision. Servo-controlled high-low file conversion device shortens the time and makes the transfer fast and stable.
3.Digital grinder and EDM can use at least three.
The X, Y, and Z three-axis movements are smooth and smooth, making the parameter setting of the controller simpler, allowing the finished product to obtain high precision, smooth arc contact, and reducing surface roughness.
4.A few explanations in practical applications
The use of high precision and low backlash combined with precision ball screws makes the control system simple 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. Because the gears are all ion-nitrided, the surface magnetic layer is wear-resistant, and the substrate maintains its toughness. The hard cutting method can produce high precision and low backlash planetary gear reducer with few variations and correct tooth profile.
