Precision turning parts for high pressure gas interface

This type of part is a precision components manufactured through high-precision CNC turning and turn-milling compound processing. It is widely used in precision fluid systems, industrial automation equipment, and high-end instruments, with strict requirements on dimensional consistency, coaxiality, and surface quality. • Dimensional tolerance: ±0.01 mm ～ ±0.005 mm (local critical dimensions can be stricter) • Coaxiality / circular runout: ≤ 0.01 mm • Surface roughness: Ra 0.8 ～ 1.6 μm (critical sealing surfaces can be lower)           A comprehensive quality inspection system has been established during the production process of such precision machined parts, covering three stages: incoming material inspection, in-process inspection, and final inspection. Key dimensions are measured online using digital micrometers, pneumatic gauges, and height gauges. Geometric tolerances such as coaxiality, roundness, and positional tolerance are precisely inspected with a Coordinate Measuring…
