Custom shafts with accurate diameters, shoulders, keyways, and threaded features.
Frequently Asked Questions
Most common carbon steel grades can be CNC machined, but machinability depends on carbon content, hardness, and material condition. Free-machining grades such as 12L14 generally cut more easily than hardened medium-carbon steels.
It depends on the part’s requirements. 1018 is a practical choice for general-purpose components, 1045 offers greater strength and hardening potential, while 12L14 is well suited to efficient precision turning when its material limitations are acceptable.
1018 is a low-carbon steel with good weldability and ductility. 1045 contains more carbon, offering higher strength and better hardening potential for shafts and other mechanical parts.
Yes. Unprotected carbon steel can rust when exposed to moisture. Black oxide with oil, zinc plating, and powder coating are common protective options, depending on the operating environment and part requirements.
Yes, suitable carbon steel grades can be heat-treated after machining. Since heating and cooling may cause distortion, critical dimensions may require finishing or inspection after treatment.
Tolerances down to ±0.005 mm may be achievable for suitable features. Actual accuracy depends on part geometry, material condition, machining method, and inspection requirements.
Cost depends on material grade, part complexity, tolerances, quantity, and any required heat treatment or finishing. A CAD model and technical drawing help determine an accurate machining quote.
Yes. YUANYI has no minimum order quantity and supports one-off prototypes and low-volume production. Lead time and pricing depend on the part’s specifications.
