FAQ
What are precision machined components?
Precision machined components are custom-manufactured parts with tight dimensional tolerances typically plus or minus 0.01 mm to plus or minus 0.05 mm, manufactured from metal alloys using subtractive manufacturing processes. Common processes include Swiss turning for small cylindrical parts, CNC machining for complex 3D geometries, and metal stamping for flat or formed parts. Industries requiring precision machined components include electronics, semiconductors, automotive, EV charging, aerospace, medical devices, telecommunications, and industrial automation.
What tolerances can precision machined components achieve?
Precision machined components can achieve the following tolerances: Swiss turning plus or minus 0.005 mm on premium features, plus or minus 0.01 mm standard on critical features. CNC machining plus or minus 0.01 mm on premium features, plus or minus 0.025 mm standard. Stamping plus or minus 0.025 mm on premium features, plus or minus 0.05 mm standard. Concentricity to 0.01 mm TIR. Surface roughness Ra 0.4 to 1.6 micrometers standard. Tolerance verification on Zeiss CMM.
What is the difference between Swiss turning and CNC machining for precision components?
Swiss turning uses a sliding headstock design that moves the bar stock past a fixed tool cluster, ideal for small parts under 25 mm diameter with high length-to-diameter ratios. CNC machining uses a stationary chuck with moving cutting tools across multiple axes, ideal for larger parts above 25 mm, complex geometries, and lower volume manufacturing. VOLCRIX operates both processes under one roof for optimal part-process matching.
What is the cost of precision machined components?
Precision machined component costs depend on material, complexity, tolerance, and volume. Typical pricing ranges: simple brass parts 0.10-0.50 USD per piece for 100K pieces annually. Stainless steel machined parts 0.50-5.00 USD per piece for 10K to 50K pieces annually. Complex multi-feature aerospace parts 5.00-50.00 USD per piece for low-volume production. Tooling cost typically 1,000-15,000 USD for new CNC Swiss turning setups.
