Typical lead time for custom gears range from 30-70 days normally, though complex or large-volume projects may take 60-80 days or more.
Several factors influence this timeline.
- First, the gear type (e.g., spur, helical, bevel, or worm) and material (steel, brass, plastic, or exotic alloys) determine machining difficulty.
- Second, the manufacturing process—hobbing, shaping, grinding, or 5-axis CNC milling—impacts speed; grinding for high-precision gears adds significant time.
- Third, heat treatment and surface finishing (e.g., carburizing, nitriding, or phosphate coating) require additional days.
- Fourth, tooling availability: standard cutter stocks shorten lead times, but custom-designed hobs or form tools extend them.
- Finally, quality assurance steps like coordinate measuring machine (CMM) inspection and gear metrology reports add 2–5 days. For urgent needs, many shops offer expedited services (e.g., 2-week rush) at a premium.
To avoid delay, we suggest you prepare order in advance so as to save enough time for production.
