Custom CNC Turn-Machined Stainless Steel Long Shaft
This custom stainless steel long shaft is a high-precision mechanical component manufactured by advanced CNC turn-mill composite machining technology. The shaft features a multi-structure integrated design, including a precision thread section, a smooth long shaft body, and a square positioning block with symmetrical through holes. The one-piece forming process ensures excellent concentricity, straightness, and structural stability, avoiding assembly deviation and mechanical shaking during high-speed operation. Made of high-quality industrial stainless steel, the part provides outstanding anti-rust performance, strong tensile strength, and long service life, making it perfectly suitable for continuous working industrial environments.
- Integrated one-piece structure: The thread segment, long shaft body, and square hole block are integrally machined with no secondary welding or splicing, ensuring ultra-high structural stability.
- Strict precision control: Controlled micron-level tolerance, high concentricity, and straightness effectively reduce vibration and noise during mechanical movement.
- Premium stainless steel material: Optional 303, 304, or 316 stainless steel offers excellent corrosion resistance, oxidation resistance, and mechanical hardness for harsh working conditions.
- Precision thread & hole positioning: Standard thread pitch and symmetrical hole spacing ensure accurate locking, positioning, and smooth assembly matching.
- Smooth burr-free surface: Fine turning and milling processes ensure a clean surface without burrs, scratches, or tool marks, ready for direct installation.
- Full custom support: Customizable total length, shaft diameter, thread specification, hole position, hole size, and square block size according to customer drawings.
- Stable batch consistency: Fixed machining parameters and professional quality inspection ensure uniform dimensions and performance in mass production.

Q1: Can I customize the shaft length and thread size?
A1: Yes. We provide full drawing customization. Shaft length, outer diameter, thread standard, hole spacing, and square block size can all be modified according to your technical requirements.
Q2: Which stainless steel grade is best for long-term outdoor use?
A2: 316 stainless steel is the best choice for humid, outdoor, or corrosive environments. For standard indoor automation equipment, 304 and 303 stainless steel are more cost-effective.
Q3: Do you provide inspection reports?
A3: Yes. We provide dimensional inspection reports, material test certificates, and full quality records for batch orders to ensure stable quality.
Q4: What is your production lead time?
A4: Prototype samples take 7-10 working days. Mass production delivery time is based on quantity and processing difficulty.
