· Product Overview
This precision-engineered component is a custom CNC-machined part crafted from high-grade stainless steel, featuring a distinctive stepped conical and cylindrical geometry with a precision-machined tip. Designed for applications requiring exceptional dimensional accuracy, surface finish, and structural integrity, it serves as a critical nozzle, guide pin, or precision shaft in industrial equipment, fluid handling systems, and precision machinery. The component’s smooth, polished surface and tight tolerances ensure optimal performance in high-pressure, high-temperature, or corrosive environments.
· Core Specifications
| Specification | Details |
|---|---|
| Material | 304 / 316 Stainless Steel (customizable to titanium or alloy steel for extreme environments) |
| Surface Finish | Precision-machined and polished to Ra ≤ 0.4μm, with optional electropolishing or passivation for enhanced corrosion resistance |
| Tolerance Standards | ±0.005mm for critical dimensions, conforming to ISO 2768-m and DIN 6700 |
| Machining Processes | CNC turning, precision grinding, and polishing |
| Key Features | Stepped conical tip for precision alignment or fluid control, precision cylindrical body for mounting, and a precision-machined end face for sealing or contact applications |
