Machining
After welding and preliminary assembly, the semi-finished product already possesses its basic form and core structure. However, to ensure perfect integration with external systems and meet final performance requirements, we must meticulously refine its key interfaces and functional surfaces. This is the core task of machining, especially computer numerical control (CNC) machining. We use multi-axis CNC machining centers, which act like highly intelligent sculptors, precisely controlling the tool's movement trajectory in space based on a digital 3D model program.
During this process, the tool performs milling, drilling, tapping, and turning operations on specific parts of the workpiece to remove excess material and precisely shape every plane, hole, thread, and sealing groove. What we pursue is not only macroscopic dimensional accuracy but also microscopic geometric tolerances—such as flatness, perpendicularity, concentricity, and position. The achievement of these precisions directly determines several key product attributes: firstly, interchangeability; high-precision machining ensures that any part of the same model can be easily installed and function identically, facilitating mass production and maintenance. Secondly, performance is crucial. For example, a perfectly sealed surface ensures that gaskets or sealing rings are evenly compressed, achieving zero leakage; a high-smoothness flow channel inner wall significantly reduces fluid resistance. Finally, overall quality is paramount. Precise fit eliminates unnecessary assembly stress, ensuring smooth component movement and enhancing the overall rigidity and stability of the product.
Machining is the final calibration and finishing of the previous manufacturing results. It transforms a "raw" semi-finished product into a precision component with accurate dimensions, standardized interfaces, and ready-to-use specifications. This process serves as a bridge connecting the product's internal manufacturing quality with external application requirements; its level directly determines the product's final performance, reliability, and professional quality.
