Datum dimensions
Which dimensions establish mounting distance, shaft location and the relationship to the tooth geometry?
Manufacturing & quality
Manufacturing & Quality for Spiral Bevel Gears
The manufacturing route is planned around the controlled drawing and the acceptance method. The aim is to keep blank datums, heat-treatment condition, tooth finishing and final inspection connected rather than treating them as isolated operations.
Process route
1
Drawing & datum review
Confirm the gear pair, machining references, interfaces and inspection requirements.
2
Blank & machining preparation
Plan turning and interface machining so later gear operations have stable references.
3
Gear cutting & heat treatment
Use the ordered gear system and protect critical surfaces according to the process plan.
4
Finishing & inspection
Finish teeth where specified, verify drawing characteristics and prepare agreed records.
Inspection scope should be agreed before production
Not every part needs the same report. A replacement pair may depend on contact, mounting geometry and dimensional comparison with a sample. A drawing-controlled production part may call for a defined gear quality standard, runout, bore or spline checks and material/heat-treatment records. Put these expectations into the RFQ so they can be included in the route and quotation.
Typical inspection questions
Pair identification
Are the mating components controlled as a set, and how must hand or pair marking be managed?
Gear quality
Which gear-quality or tooth inspection requirement applies to the ordered configuration?
Material condition
Which material, heat-treatment and hardness requirements are stated on the controlled drawing?

The more clearly the mating relationship and assembly datums are defined, the faster the configuration can be reviewed.
Ordering & delivery guidance
MOQ is flexible by product type, manufacturing route and total order value. Suitable new projects may request 1–5 sample pieces at sample pricing. Mixed models can be combined when the order total reaches approximately USD 1,500. Orders of 1–2 pieces can be reviewed, although unit cost is normally higher.
Typical planning windows are 10–25 working days for standard parts, 20–45 working days for customized components and 45–120 working days for project-type equipment or assemblies. EXW, FOB, CIF and DAP are commonly supported; FCA, CFR, CPT, CIP and DDP can be discussed for the shipment.
