Some CNC panel saws for woodworking use synchronous belts. However, synchronous belts have a certain tension, and over time, this can lead to a decrease in accuracy. CNC panel saws have very strict accuracy requirements. They are typically designed for heavy-duty, high-precision applications, where the torque required for load movement often far exceeds the torque capacity of the servo motor itself. This problem can be effectively solved by using a planetary reducer connected to the servo motor to increase its output torque.
The advantages of using Zhuochuang planetary gear reducers are as follows:
1. Increase torque:
One way to increase output torque is to directly increase the output torque of the servo motor. However, this method requires expensive, high-power servo motors with a more robust structure. Since the increase in torque is proportional to the increase in control current, larger drivers, power electronic components, and related electromechanical equipment are needed, significantly increasing the cost of the control system. A better approach is to use a Shenzhen Zhuochuang dual-support planetary gearbox connected to the servo motor. (The Zhuochuang dual-support planetary gearbox features a one-piece structure between the output shaft and planetary carrier, and a high-speed bearing at the connection between the input shaft and planetary carrier. Its advantages include high transmission precision, smoother gear transmission, low transmission noise, high efficiency, and better stability.)
2. Improve performance:
It is understood that improper matching of load inertia is one of the biggest causes of servo control instability. For large load inertia, the inverse square of the reduction ratio can be used to adjust the optimal equivalent load inertia to obtain the best control response. Therefore, from this perspective, planetary gear reducers offer the best matching for control response in servo applications. (Zhuochuang planetary gear reducers use an integrated structure for the input shaft and sun gear, while competitors use a separate structure connected by rivets or keys. Compared to competitors, Zhuochuang's integrated structure eliminates the error in the connection between the input shaft and sun gear, resulting in higher precision, higher concentricity, greater torque capacity, and smoother transmission.)
6. Increase equipment lifespan:
Planetary gear reducers can also effectively solve the problem of reduced low-speed control characteristics of motors. The controllability of servo motors decreases with speed, especially noticeable in signal acquisition and current control stability at low speeds. Therefore, using a gear reducer allows the motor to achieve higher speeds. (The internal gear ring of the Zhuochuang planetary gear reducer is inserted directly into the housing body. It is made of high-quality 42CrMo alloy steel and undergoes a tempering and nitriding process using an imported gear shaper to ensure precision and hardness. Other manufacturers use a split structure, where the internal gear ring is mostly broached before being inserted into the housing. Some manufacturers also use gear shaping, but their materials are mostly 45 steel without any treatment.)
Therefore, based on the above analysis, Zhuochuang's double-support planetary reducer is the best choice for CNC woodworking machinery cutting machines. The models used in CNC cutting machines are ZCA115-5 and ZCA90-5.
