Machining Instructions – Best Practices
- Design Review – Upload your CAD model (STL, STEP, IGES) for a free DFM analysis. Our engineers will flag potential issues such as under‑cutting, unsupported overhangs, and tool‑reach limitations.
- Material Selection – Choose the alloy that balances strength, machinability, and cost. For high‑speed aluminum CNC Lathe Machine Parts, consider 6061‑T6; for high‑temperature or corrosive environments, Inconel 718 is recommended.
- Tolerance Allocation – Assign tighter tolerances only to functional features (e.g., bearing seats, mating surfaces). This reduces machining time and cost without compromising performance.
- Surface Finish Specification – Define Ra values early. If a surface must be ≤ 0.2 µm, request a post‑process polishing or abrasive flow machining (AFM) step.
- Tooling Choice – Carbide end‑mills with TiAlN coating are optimal for stainless steel; high‑speed steel (HSS) for brass and softer alloys. For deep‑cavity parts, use long‑reach tools with low‑runout spindles.
- Fixturing – Provide accurate drawing of the fixture or allow us to design a custom fixture. Proper fixturing eliminates deflection and ensures repeatability.
- Lead Time Planning – Standard production lead times: 7‑10 business days for 1‑100 pcs; 15‑20 days for 101‑1 000 pcs. Rapid‑prototype runs (≤ 48 hrs) are available for standard alloys.
