Full Product Description

Custom 316L Stainless Steel Precision Metering Cylinder

This complex metering component cannot be manufactured with ordinary 3-axis CNC machines. Our imported Mazak 7-axis 5-link turn-mill platform integrates all processes including full OD turning, angled face milling, internal bore precision boring, drilling, tapping, and involute spline hobbing, all done in one single part clamping operation. It completely eliminates accumulated positioning error caused by multiple re-fixturing steps that separate conventional turning and milling workflows will introduce, and delivers unmatched concentricity and seal face alignment that cannot be achieved on standard machines.

Made from solid 316L stainless steel billet, the part inherits excellent corrosion resistance, chemical compatibility for daily chemical fluid media, and structural rigidity for high pressure metering applications. All critical seal mating faces keep surface roughness down to Ra 0.8 μm ~ Ra 1.6 μm, forming perfect zero-leak sealing with matching seals. We support full custom modification on all dimensions, bores, spline parameters, and flange layout, all parts 100% follow your 2D drawings or 3D CAD models. The finished cylinders are widely used in daily chemical fluid machinery, industrial automation metering systems, general mechanical assemblies, and automotive precision transmission components.

Core Machining Advantages & Difficulty Breakdown

1. All-In-One Composite Structure Machining: Our Mazak 7-axis 5-link platform completes turning, angled milling, precision boring, cross-hole drilling, tapping and spline hobbing in one setup, there is no need to unload and re-clamp the part between different processes, no accumulated positioning offset that breaks concentricity.

2. Tightest Tolerance Control: We unify all features to one single master datum reference during the full machining sequence, lock the total part concentricity under ≤0.04 mm, guarantee perfect interchangeability between replacement assemblies and reliable zero-leak seal performance.

3. Hard-to-Machine 316L Material Expertise: 316L austenitic stainless steel generates high cutting heat, easy to cause tool wear and built-up edge burr. Our optimized low-feed high-speed machining parameters + dedicated anti-vibration tool holders eliminate this issue, no tool mark left on the precision seal faces.

4. Single Clamp Zero-Reset Advantage: Mazak 7-axis 5-link system realizes full feature completion in one clamping, zero reset positioning deviation, every part in the batch shares identical dimension consistency, drastically improves production efficiency for complex precision metering cylinders.

5. Premium Surface Quality: All seal and mating faces are finished with dedicated fine machining passes, sharp edges are fully broken and deburred, no micro burrs remain on all internal bores and spline grooves, perfectly adapted for corrosive media contact working environments.
