CNC Machined And Electropolished 316 Stainless Steel Parts For Automation Systems

15+ Years of Experience On CNC Machining:

With 15+ years in custom CNC precision machining services, JINGXIN has developed focused expertise in crafting parts for automation systems—specifically CNC machined and electropolished 316 stainless steel parts. Located in Dongguan City, China, our professional team adopts rational manufacturing processes, tailored solutions, and meticulous workmanship to supply high-quality one-stop custom CNC precision machined parts. These include core electropolished 316 stainless steel components for automation systems, alongside parts made of stainless steel (other grades), aluminum, iron, and more.

We Focus on:

Custom non-standard CNC precision machining services & milling parts, with a key focus on CNC machined and electropolished 316 stainless steel parts designed for automation systems. These parts are critical for the smooth, long-term operation of automation equipment, such as:

•Sensor mounting brackets (resisting oil and moisture in factory automation environments)

•Pneumatic cylinder fittings (needing low friction and corrosion resistance for repeated actuation)

•Conveyor system drive components (requiring durability against wear and chemical exposure)

The electropolished finish of 316 stainless steel reduces surface friction (preventing jams in automated motion) and enhances corrosion resistance (ideal for cleanrooms or industrial settings with coolants), while the material’s inherent strength meets automation’s high-load demands. Our product scope also covers fittings, valves, hydraulic components, electric motor parts, transmission and pump parts, sprocket wheels, wear parts on packing machines, and electronic and medicinal pieces.

Our Advantage:

1.Advanced Equipment: We operate a world-class facility equipped with a variety of precision CNC machines (Brother, HAAS, Mazak), vertical milling centers, and precision milling and turning lathes (including 3-axis, 4-axis, and 5-axis models). Our CNC machines are optimized for machining 316 stainless steel—its higher chromium-nickel content requires stable cutting forces, which our rigid equipment delivers to maintain tight tolerances. We also have in-house electropolishing equipment, ensuring consistent, uniform surface finishes (free of tool marks) that are critical for automation part performance.

2.Complete Machining Capability In-House: We adhere to the ISO 2768-F/M machining standard for tolerances, producing parts in a wide range of sizes and complexities—from small electropolished 316 sensor brackets to large conveyor drive components. For 316 stainless steel parts, our post-machining electropolishing process achieves a surface roughness of Ra ≤ 0.2μm, reducing particle adhesion and making parts easier to clean (a must for automated food or pharmaceutical production lines). Maximum CNC milling capability is detailed in the list below.

3.Raw Material: We guarantee 100% compliance of all materials with RoHS standards and your design specifications. For 316 stainless steel (our core material for automation parts), we source high-purity billets with low carbon content (316L grade optional) to enhance weldability and corrosion resistance—critical for parts like automated valve bodies. We provide material certificates, SGS reports, and electropolish quality reports (verifying surface finish and corrosion resistance) upon request. Our material range also includes steel, aluminum, other stainless steel grades, titanium, and engineering plastics (e.g., PEEK, PC, POM); more details refer to the list below.

4.Order Quantity: We accept orders starting from 1 unit, supporting both short-run precision CNC milling & turning and large-volume production—whether you need a small batch of custom electropolished 316 cylinder fittings or mass-produced conveyor components for automation lines.

5.Quick Turnaround: We provide quotes within hours and fast delivery in days, backed by a skilled and professional R&D team. Even for parts requiring electropolishing (an additional step to optimize automation performance), we streamline workflows to avoid delays—ensuring your automation system assembly stays on schedule.

6.Our Customers: Our customers are from the EU and North America, many of whom are leading automation equipment manufacturers. They rely on our CNC machined and electropolished 316 stainless steel parts to ensure their systems run with minimal downtime (thanks to corrosion resistance) and precise motion (thanks to smooth electropolished surfaces).

Quality Assurance:

What we do to ensure you receive high-quality CNC Precision Machining parts from JINGXIN: We declare here that we will be responsible for our precision machined parts at all times—especially for CNC machined and electropolished 316 stainless steel parts, where quality directly impacts automation system reliability.

1.100% inspection before shipping: For 316 stainless steel parts, we conduct specialized tests—including spectral analysis (to verify 316 material composition), salt spray testing (to confirm corrosion resistance), and surface roughness measurement (to check electropolish quality). An inspection shipment report for each piece of precision CNC milling part is available. We implement ISO quality control throughout the whole production process, from 316 material incoming checks to electropolish final inspection.

2.We have served Volvo Auto Corp since 2016 as an approved precision CNC milling company in China (supplying high-precision auto parts), and we also have a 5-year+ track record of partnering with EU-based automation brands—providing electropolished 316 stainless steel parts that meet strict industrial automation standards, with no complaints so far.

3.In case any precision machined part (including electropolished 316 stainless steel parts) is outside tolerance, fails to meet your electropolish requirements, or deviates from your special specifications, we will remake and deliver them as fast as we can, 100% free from our side.

4.Over the past years, JINGXIN CNC Milling Company has manufactured thousands of pieces of precision CNC machined components for our customers—including tens of thousands of CNC machined and electropolished 316 stainless steel parts for automation systems. The 99.9% satisfaction feedback (especially regarding the durability and precision of our automation parts) drives us to supply more quality precision machined parts to meet customer's requests.
