The quality of a finished self-drilling screw is fundamentally determined by the quality of its blank. Imperfections in the blank-such as inconsistent volume, poor head shape, or internal flaws-cannot be rectified in later processing stages and will inevitably compromise the final product's performance. Our machine for self drilling screw production is designed to be the cornerstone of quality, producing blanks of such exceptional consistency and integrity that they become a significant value-added component in your manufacturing process.
The machine's contribution to quality begins with its precision. The control precision of the second-axis cam, maintained within a tight 0.03-0.05mm tolerance, ensures that every transfer and forming action is executed with exacting repeatability. This results in blanks with exceptionally uniform head dimensions and shank volumes. This uniformity is critical for the subsequent thread rolling and drill point fabrication, as it ensures consistent material flow during threading and provides a perfectly symmetrical base for grinding the precise drill point geometry. A blank from our machine gives downstream processes the best possible chance of success, leading to screws with accurate threads, centered drill points, and reliable clamping force.
The long-term value proposition is deeply embedded in the machine's robust construction and the resulting blank quality. Durable components like the precision cast steel tie rods and the high-precision punch die holder maintain alignment and stability over millions of cycles, ensuring that the first blank and the last blank in a production run are virtually identical. This minimizes quality variations and reduces the rate of scrap and rework after thread rolling and point grinding. Furthermore, the "near-net-shape" capability of the cold heading process minimizes material waste right from the start. By investing in a cold header that produces superior blanks, you are not just purchasing a machine; you are investing in enhanced final product quality, reduced total manufacturing costs, and a strengthened reputation for reliability in the competitive self-drilling screw market.
