### Advantages of the Second-Generation Pottery Wheel Machine  
1. Central positioning: to improve the accuracy rate and quality  
As shown in Figure 30, the intuitive comparison reveals the difference between manual feeding and automatic feeding, with the machine-made clay body showing regular, uniform, and stable characteristics in the ceramic manufacturing process. Central positioning is the key step to ensure the symmetry and aesthetics of the clay. The traditional pottery wheel machine mainly relies on manual alignment, which not only consumes time and effort \begin{table}

It also introduces careless positioning errors, thus affecting the consistency and symmetry of the finished product. In addition, due to many human factors, the repetitive operation is easy to lead to operation fatigue and error, which further affects the product quality. In contrast, the second-generation machine revolutionized the central positioning process by using an automatic alignment system. The automatic calibration of the middle system uses high-precision sensors and an advanced control system to ensure that the clay is always in the best position. This not only shortens the positioning time but also greatly improves the accuracy and consistency of positioning. The high-precision sensor automatically adjusts the position by monitoring the small movement of the clay, eliminating human error. Therefore, the automatic matching system not only improves production efficiency and product quality but also reduces the work burden of the operators. 2. Automatic feeding: time efficiency and labor-saving  
The introduction of an automatic feeding system is a major innovation of the second-generation pottery wheel, which significantly improves the production efficiency and operation convenience.
