This equipment is characterized by its stable operation, high processing precision, and strong adaptability to small and medium-sized workpieces, making it an indispensable tool in modern precision manufacturing processes.
In terms of working principle, the Single Rotary Table High-precision Shot Blasting Machine operates based on the principle of centrifugal acceleration. The core component is the shot blasting wheel, which rotates at high speed under the drive of a variable-frequency motor to generate strong centrifugal force. This force accelerates the shot material (such as steel shot, stainless steel shot, or aluminum shot) to a high velocity, and the shot is then projected onto the surface of the workpiece placed on the rotary table. The rotary table, driven by a precision servo motor, rotates at a controllable speed, ensuring that every part of the workpiece surface is uniformly impacted by the shot material. During the process, the shot material removes impurities such as rust, oxide scale, and oil stains on the workpiece surface through mechanical impact, and at the same time, forms a certain roughness on the surface, which helps to improve the adhesion of subsequent processes such as painting and coating. After the shot blasting is completed, the shot material and the debris are separated through the dust removal and shot recycling system, and the clean shot material is recycled for reuse, realizing the efficient utilization of resources and environmental protection.
