The application of direct-connected planetary reducer and hollow planetary reducer in CNC PCB processing equipment has its own advantages and disadvantages. Each of them is described below.
Directly connected to the planetary reducer:
The advantages of the direct-connected planetary reducer in CNC PCB processing equipment mainly include:
1) High transmission accuracy: The gear meshing accuracy of the directly connected planetary reducer is high, which can reach less than 1 arc minute, which belongs to the high-precision reducer compared with other types of reducers. In CNC PCB processing equipment, high-precision transmission can improve machining accuracy and stability.
2) Large transmission speed ratio: There are multiple groups of gear meshing transmission directly connected to the planetary reducer, and the number of gear sets is large, and the transmission speed ratio increases accordingly. This feature enables the direct-connected planetary reducer to achieve a wide range of speed regulation on CNC PCB processing equipment to adapt to different processing needs.

3) Strong bearing capacity: The direct planetary reducer has many teeth and meshing gear transmission at the same time, and the material used in the rack has high strength. After precision machining, the overall bearing capacity of the planetary reducer is effectively improved. This feature enables the direct-attached planetary gearbox to withstand large loads, and is suitable for heavy-duty cutting and high-speed operation.
4) High efficiency and smooth action: each group of gears in the direct-connected planetary reducer only engages a single tooth surface when decelerating, so the tooth surface stress requirement is greater when the transmission torque is equal. The gear design must use a large modulus and thickness. The larger the gear modulus, the greater the deflection tolerance between the gears, the higher the gear clearance formed, and the greater the backlash accumulated between the reduction ratios. The precision planetary reducer combines the unique multi-point uniform tight fit structure and the arc structure of the outer gear ring, so that the external gear ring and the planetary gear are tightly combined, and have a high degree of close fit between gears. In addition to improving the efficiency of the gearbox, the design itself enables high-precision positioning. This feature enables the direct planetary reducer to achieve smooth high-speed operation and improve processing efficiency on CNC PCB processing equipment.

Coaxial reducer:
The advantages of coaxial reducer in ultrasonic cleaning equipment mainly include:
1) High transmission accuracy: The gear meshing transmission accuracy of the coaxial reducer is high, which can reach less than 1 arc minute. This high transmission accuracy is conducive to improving the cleaning effect and stability of ultrasonic cleaning equipment.

3) Compact structure: The structure of the coaxial reducer is relatively compact, small in size, light in weight, and occupies less space. In ultrasonic cleaning equipment, this feature is conducive to reducing the overall size and weight of the equipment, and facilitating the installation and operation of the equipment.
4) High reliability: The design of the coaxial reducer is simple, the structure is stable, the parts are wear-resistant, and the service life is long. This feature makes the coaxial reducer have high reliability in ultrasonic cleaning equipment and reduces the probability of equipment failure.
The disadvantages of coaxial reducer mainly include:
1) Limited bearing capacity: The bearing capacity of the coaxial reducer is relatively limited and may not be able to bear large loads. In situations where larger loads need to be carried out, other types of gear units may be required.
2) Weak impact resistance: The impact resistance of the coaxial reducer is relatively weak and is easily affected by sudden impact loads. In some high-impact situations, additional measures may be required to improve the impact resistance of the device.
