A part drawing is essential when requesting a high-volume machining quote, but it does not always tell the full production story.
An accurate RFQ should also explain expected volumes, material specifications, critical tolerances, secondary operations, quality requirements, and delivery needs. Providing this information upfront helps your machining supplier develop realistic pricing and recommend the most efficient production approach.
Quick Answer: What Should an OEM Machining RFQ Include?
Include the following information whenever it applies:
- Current part drawing and revision
- Initial order quantity
- Estimated annual usage
- Typical release quantities
- Exact material grade
- Critical dimensions and tolerances
- Secondary operations and finishes
- Inspection and documentation requirements
- Packaging and delivery expectations
The RFQ does not need to be lengthy. It simply needs to describe the completed part and the production program clearly.
Submit the Current Part Drawing
Provide the latest controlled drawing with the correct revision number.
The drawing should clearly identify dimensions, tolerances, threads, surface finishes, material specifications, and other requirements used to approve the finished part. Even a minor revision can change tooling, inspection, cycle time, or pricing.
For complex parts, ask the supplier how it prefers to receive supporting CAD files.
Provide Quantity and Annual Usage
For repeat production, the first order quantity is only part of the equation.
Also provide:
- Estimated annual usage
- Typical release quantity
- Expected ordering frequency
- Anticipated future volume
These details help the supplier evaluate capacity, tooling, setup costs, and the most appropriate production process.
Depending on the part, CNC turning, Swiss CNC machining, automatic screw machining, or multi-spindle production may offer the best balance of precision, consistency, and cost.
Specify the Material and Critical Tolerances
Identify the exact material grade, alloy, temper, or condition. Broad descriptions such as “steel” or “aluminum” may not provide enough information for firm pricing.
Also note whether you require:
- Domestic material
- Material certifications
- Heat or lot traceability
- A customer-specific material standard
- Approval before using alternate materials
Clearly mark the dimensions that are critical to fit, function, sealing, alignment, or assembly. This helps the supplier plan the appropriate tooling, process controls, and inspection methods.
Include Secondary Operations and Quality Requirements
Your RFQ should describe the finished component—not only the machining operation.
List required secondary services such as heat treating, plating, anodizing, passivation, grinding, broaching, deburring, cleaning, part marking, or light assembly.
Quality requirements may include:
- First-article or initial sample reports
- PPAP documentation
- Material certifications
- Certificates of conformance
- Dimensional inspection reports
- Statistical process control data
- Heat or lot traceability
Including these requirements during quoting helps avoid changes to pricing or lead times later.
Explain Packaging and Delivery Needs
Identify any special packaging needed to protect threads, cosmetic surfaces, precision features, or finished coatings.
Also include the requested delivery date and anticipated release schedule. For ongoing programs, explain whether parts will be ordered in full quantities or through scheduled releases.
These details help the supplier plan production, inventory, packaging, and shipping around your actual requirements.
What Commonly Delays an OEM Machining Quote?
The most common issues are straightforward:
- An outdated drawing
- No annual usage estimate
- An incomplete material specification
- Missing secondary operations
- Unidentified quality documentation
- No requested delivery schedule
Not every requirement needs to be finalized before you submit an RFQ. Clearly identify any open items and explain whether alternate materials, tolerances, finishes, or production methods may be considered.

People Often Ask About High-Volume Machining RFQs
Why does annual usage matter?
Annual usage helps the supplier evaluate equipment, tooling, production capacity, and quantity pricing. The most efficient process for 1,000 parts may differ from the best process for 100,000 parts.
Can OEM buyers request several quantity price breaks?
Yes. Pricing at several quantities can help purchasing teams compare costs and plan future releases.
Should PPAP and inspection requirements be included in the RFQ?
Yes. PPAPs, inspection reports, certifications, and traceability requirements affect quality planning and should be identified before pricing is finalized.
What if some requirements are still undecided?
Submit the available information and clearly identify the open items. The supplier can explain what must be finalized before providing firm pricing.
