OEM Customized Stainless Steel Precision Turning Parts with CNC Machining
OEM Customized Stainless Steel Precision Turning Parts with CNC Machining is the turnkey answer for engineers who refuse to compromise on roundness, surface finish, or lot-to-lot consistency. Every component begins with mill-certified 303, 304, 316L, or 17-4 PH stainless bar stock that is ultrasonically tested for micro-cracks before it even reaches the lathe. Our Miyano BNA-42MSY 7-axis CNC turning centers equipped with 0.1-µm glass scales and high-pressure coolant through the turret hold diametral tolerances down to ±0.005 mm and surface finishes as smooth as Ra 0.2 µm—ideal for mating shafts in peristaltic pumps, beverage valves, or medical-grade actuators where any leakage or backlash is unacceptable.
Live tooling and Y-axis interpolation mill off-center flats, cross-holes, and Torx-Plus sockets in the same setup, eliminating secondary operations and guaranteeing true position within 0.01 mm to the turned datum. After machining, parts are passivated in citric acid baths to remove free iron, then vacuum-bagged with desiccant to prevent transit corrosion. For food or pharmaceutical OEMs we offer electropolishing to ≤0.25 µm Ra, followed by sterile double-bagging in ISO 7 clean-room conditions and lot-specific certificates that satisfy FDA 21 CFR 820 traceability audits.
Design support is included at no cost: upload a STEP file and receive a DFM report within 24 hours that recommends optimized corner radii, minimum wall thickness, and GD&T callouts that reduce cycle time by up to 30 %. Prototypes ship in 3–5 days via our in-house 3D-printed polymer mandrel process that replicates final geometry for fit checks before hard tooling is cut. Production lots from 50 to 500,000 pieces are scheduled on lights-out robotic cells with automatic in-process gauging; every tenth part is laser-scanned against the golden profile, feeding SPC charts that customers can view in real time through a secure portal.
Secondary services—laser marking with 2D data-matrix codes, dry-film Teflon coating for galling resistance, or clean-room assembly with fluorosilicone O-rings—are handled under the same roof, eliminating vendor fragmentation. All work complies with ISO 9001:2015 and IATF 16949 where required, and material certificates, PPAP Level 3 documentation, and RoHS/REACH statements ship with every lot. Whether you need a 0.3 mm thin-wall cannula hub or a 250 mm long drive shaft with helical knurling, our OEM Customized Stainless Steel Precision Turning Parts deliver aerospace-grade quality at automotive volumes, on time and on budget.
