How to Request a Machining Quote with a Complete RFQ Package
Provide the technical and commercial inputs needed to review manufacturability, define inspection scope, and prepare a responsible quotation.
2D Drawing and Model
Send the current revision-controlled 2D drawing and, when available, a 3D model showing geometry, datums, tolerances, threads, and critical notes.
Material and Condition
Specify the required material grade, condition, heat-treatment requirement, and any material documentation needed before SUUXIANG evaluates the proposed manufacturing route.
Process and Finish Requirements
Identify surface finish, coating, EDM, grinding, fitting, or secondary-process needs, including cosmetic areas and surfaces that require controlled handling.
Critical Features and Inspection
Mark critical dimensions, mating features, datum relationships, and required inspection reports so the measurement method and traceability expectations can be reviewed.
Quantity and Delivery Target
State prototype or production quantity, anticipated repeat demand, target delivery date, and any partial-shipment, packaging, or scheduling constraints affecting the quotation.
Application and Assembly Context
Share the part function, mating-component information, and known design concerns so tool access, tolerance stack, and process risks are addressed early.
Prepare the Details That Determine Machining Feasibility
Identify CTQs and Datums
Mark critical-to-quality dimensions, functional datums, and tolerance relationships on the drawing. This lets SUUXIANG assess setup strategy, inspection method, and tolerance stack before a process route or quotation is based on assumptions.
- Identify features that control fit, sealing, alignment, or motion
- Show datum references and applicable GD&T requirements
- Separate functional tolerances from noncritical dimensions
- State required inspection reports or measurement methods
Define Surface Requirements
Specify surface finish, edge condition, cosmetic priorities, coatings, and heat-treatment requirements where they affect function. A clear callout helps determine machining sequence, stock allowance, protection needs, and whether a secondary process must be considered.
- Call out Ra requirements only on relevant surfaces
- Note burr, edge-break, and cosmetic acceptance criteria
- Identify masking, coating, or post-treatment requirements
- State material grade and required condition
Review Access and Process Needs
Deep pockets, narrow slots, sharp internal corners, hardened features, and fine details can change the route. Flagging these features early supports a practical review of cutter access, electrode strategy, wire path, EDM requirements, and grinding stock.
- Identify restricted tool access and deep-cavity features
- Flag features that may require wire or sinker EDM
- Allow grinding stock where precision grinding is required
- Share hardness or heat-treatment sequence requirements
Provide Mating Context
A drawing alone may not show how a component functions in the assembly. Include mating-part information, interface sketches, and assembly priorities so critical fits, locating surfaces, orientation, and inspection priorities can be reviewed before quotation.
- Provide mating dimensions or an assembly view when available
- Explain fit, alignment, sealing, or movement requirements
- Identify nonnegotiable interface surfaces
- Confirm revision status and applicable document set
