About This Part
Fiber optic interfaces shrink every year, and this AGT-MT-APC body packs a tapered precision bore, a controlled 40 degree end chamfer, and external turned features into 11.6 mm of diameter. The route splits the work where each machine is strongest: CNC turning roughs and finishes the external profile and datum face B, then a five-axis mill cuts the formed features and the tapered internal bore in one fixture.
The outside diameter is held at 11.6 ±0.02 mm, general features follow GB/T 1804-f, and star marked dimensions get dedicated process control. Every edge is deburred by hand under inspection, leaving a surface free of nicks, scratches, or handling marks, with the drawing specified marking applied and verified.
SUS303 cuts cleaner than 304, which matters when the part is this small: threads and chamfers come off crisp, and the free machining grade still carries the corrosion resistance a fiber optic assembly needs. Finished bodies are washed, inspected, and packed individually.

Common Questions
Why SUS303 when the design calls for 304?
303 machines significantly cleaner at this size, which keeps the small chamfers and tapered bore crisp and burr free. It keeps the corrosion resistance of an austenitic stainless; where the drawing strictly requires 304, we run 304 and adjust the process.
Can you hold ±0.02 mm on a diameter this small in volume?
Yes. The OD is finished in a dedicated turning step with in-process gauging, and the star marked dimensions are tracked lot by lot with 100 percent final checks.
Do you apply the marking in house?
Yes, marking is applied per the drawing font and position and then verified during the final inspection before packing.
