Custom CNC Machining Stainless Steel Parts​

Product Overview

This subtractive manufacturing process offers unparalleled design flexibility, accommodating everything from simple brackets to intricate aerospace components. Our machining centers handle 304, 316, 17-4 PH, and duplex stainless steels, producing parts that meet ISO 9001 and AS9100 quality standards. Whether for medical devices requiring biocompatibility or industrial machinery needing wear resistance, these custom parts balance performance, durability, and cost-effectiveness.

Product Features

Machining Precision: Multi-axis CNC centers achieve tolerances as tight as ±0.01 mm on critical dimensions, with positional accuracy of ±0.005 mm/m ensuring consistent part-to-part interchangeability.

Material Optimization: 316 stainless steel parts provide superior chloride corrosion resistance (10,000 ppm Cl⁻), while 17-4 PH offers tensile strength up to 1,100 MPa after heat treatment, ideal for high-load applications.

Surface Finish Control: Advanced tooling produces surface finishes from Ra 0.8 μm (polished) to Ra 3.2 μm (mill finish), with options for passivation, electropolishing, or PVD coating to enhance corrosion resistance.

Production Flexibility: Equipped with automated tool changers and pallet systems, our facility handles batch sizes from 10 units to 10,000+ units with lead times as short as 5–7 days for prototype runs.

Applications

These precision-machined parts serve diverse industrial sectors:

Medical Devices: Surgical instrument components and implantable hardware from 316L stainless steel, meeting ISO 13485 and biocompatibility standards (ISO 10993).

Aerospace & Defense: Hydraulic fittings and structural brackets from 17-4 PH, withstanding extreme temperature fluctuations (-55°C to 315°C).

Food Processing: Sanitary valves and conveyor components with electropolished surfaces (Ra ≤0.8 μm) to prevent bacterial growth and meet FDA standards.

Energy Sector: Pump shafts and valve trim from duplex stainless steel, resisting sulfide stress cracking in oilfield and geothermal applications.

FAQ

Q: What design files are required for custom CNC machining?

A: We accept CAD files in STEP, IGES, or SOLIDWORKS formats, with 3D models preferred for complex geometries. Our engineering team reviews files for manufacturability within 24 hours.

Q: How do you ensure dimensional accuracy across large production runs?

A: We implement statistical process control (SPC) with in-process CMM inspections every 50 parts, maintaining process capability indices (Cp/Cpk ≥ 1.33) for critical dimensions.

Q: Can you machine thin-walled stainless steel components without distortion?

A: Yes, using specialized fixturing and high-speed machining techniques (10,000+ RPM spindles) with coolant-through tools, we successfully machine walls as thin as 0.5 mm in 304 stainless steel.
