Rotary RFQ Template: 12 Fields to Prevent Rework
A practical RFQ template for OEM buyers to reduce quote loops, lock technical assumptions, and compare servo rotary suppliers on equal terms.
When two suppliers cannot quote from the same assumptions, you are not comparing suppliers, you are comparing guesswork.
Most quote delays are not caused by supplier speed. They come from missing inputs, mixed assumptions, and unclear release criteria.
Below is the RFQ structure I use to help buyer teams shorten quote loops and get technically comparable offers.
Applicability, Date, and Limits
- Last verified date: 2026-05-11.
- Applies to: rotary table and indexing-platform RFQs where engineering and procurement must sign jointly.
- Does not replace: machine safety validation, legal contract review, or customs classification decisions.
- Decision boundary: this template improves quote comparability; it does not make a weak specification technically valid.
When This Template Should Be Used
Use this template when all four conditions apply:
- You are sourcing a servo hollow rotary table or indexing platform for OEM equipment.
- More than one supplier is being compared.
- PO timing matters (launch, retrofit, or cost-down project).
- Engineering and procurement decisions must be signed off by different roles.
Do not use this as your only document for safety-critical or regulated systems. In those cases, add your internal validation protocol and legal compliance checklist.
RFQ Package Structure (Send as One Bundle)
A strong RFQ package has three sheets plus two attachments:
- Technical requirement sheet (application, load, motion, interface, environment).
- Commercial assumption sheet (Incoterm, route assumptions, payment terms, MOQ, tooling).
- Validation and acceptance sheet (sample criteria, FAT format, release gate).
- Mechanical envelope drawing (critical dimensions and clearance zones).
- Controls stack note (servo model, encoder/protocol, controller family).
If one of the five items is missing, suppliers will fill gaps with their own assumptions, which breaks comparability.
The 12 RFQ Fields to Lock Up Front
| Field | Required format | Owner | Minimum acceptable input | Typical failure if omitted |
|---|---|---|---|---|
| Application process | One sentence + duty context | System engineer | Process type and cycle target | Wrong product family quoted |
| Through-bore requirement | Diameter, tolerance, pass-through media | Mechanical engineer | Bore size and cable/air path note | Re-quote after drawing review |
| Axial/radial/moment load | Peak + continuous values, units | Mechanical engineer | Load table with direction definition | Bearing life mismatch |
| Indexing cycle and duty | Moves/hour, dwell %, accel notes | Controls engineer | Duty snapshot for worst station | Thermal underestimation |
| Positioning repeatability | Target value and measurement method | Quality + controls | Repeatability target with condition | Spec interpreted differently by each supplier |
| Servo motor brand/model | Full model code + brake option | Controls engineer | Confirmed motor SKU and revision | Flange/coupling mismatch |
| Encoder and protocol | Absolute/incremental + bus/protocol | Controls engineer | Controller and IO stack note | Late integration rework |
| Mounting interface drawing | 2D drawing with datum references | Mechanical engineer | Bolt pattern, pilot, center height | Adapter redesign after quote |
| Environment | Temperature, dust/coolant, vibration | Reliability engineer | Operating envelope statement | Seal/material mismatch |
| Annual volume and MOQ plan | Year-1, year-2, lot cadence | Procurement | Forecast bands by quarter | Lead time instability |
| Target delivery window | Required first delivery date + ramp | PM + procurement | Date and ramp schedule | Non-actionable lead-time quote |
| Validation and acceptance plan | Sample gate criteria + report format | Quality manager | FAT/SAT checkpoint list | Endless pass/fail disputes |
RFQ Completeness Score (Internal Gate Before Sending)
Use a simple internal score before release:
- Critical fields (servo model, load table, interface drawing, acceptance plan): 10 points each.
- Major fields (duty profile, environment, delivery window, volume plan): 7 points each.
- Supporting fields (process summary, protocol note, commercial assumptions): 4 points each.
Decision rule:
- 90-100: release RFQ.
- 75-89: release only with risk note attached.
- Below 75: do not send; complete missing fields first.
This single gate reduces quote loops more than any negotiation tactic.
Quote Normalization: Make Supplier Responses Comparable
Require each supplier to return the same quote structure.
| Quote line | Supplier A | Supplier B | Your normalization rule |
|---|---|---|---|
| Unit price (base route) | value | value | Compare same Incoterm and lot size |
| Unit price (tariff-stress route) | value | value | Same customs assumption window |
| Tooling/NRE | value | value | Separate one-time from recurring cost |
| Lead time (sample) | value | value | Clock starts after data freeze |
| Lead time (mass production) | value | value | Tie to approved sample gate |
| Warranty/support scope | text | text | Convert to risk-adjusted note |
Always request two commercial scenarios:
base routetariff-stress route
Without dual scenarios, "lowest quote" can become the highest landed cost after route or duty changes.
Supplier Response SLA and Clarification Loop
Set expectation in the RFQ email:
- Clarification questions due in 2 business days.
- First quote due in 5-7 business days for standard configurations.
- Change log required for every revised quote.
If clarification questions exceed 10 items, hold a 30-minute joint review call instead of email ping-pong.
Red Flags That Should Block PO Release
- Supplier quote references a different servo motor family than your RFQ.
- Load assumptions are missing peak values or direction definition.
- Repeatability value is provided without measurement condition.
- Lead time is stated without sample approval milestone.
- Commercial line includes hidden tooling in unit price.
Any two red flags together should trigger re-quote, not negotiation.
Copy-Paste RFQ Email Template
Subject:
RFQ - Servo Hollow Rotary Table - [Project Name] - [Target PO Date]
Body:
Hello [Supplier Team],
Please quote based on the attached RFQ package (Technical, Commercial, Validation sheets + drawings).
Required quote structure:
1) Unit price under base-route assumptions
2) Unit price under tariff-stress assumptions
3) Tooling/NRE separated from recurring unit price
4) Sample lead time and MP lead time, each with start condition
Please submit clarification questions within 2 business days and first quote within 5-7 business days.
Best regards,
[Name]
[Company]If you want a fast pre-check of your RFQ package quality, send the draft to [email protected] before supplier release.
