How to Prepare a Design for a CNC Machining Quote

Core Principle

Providing clear, complete, and standardized manufacturing information is the key to receiving a fast and accurate quote. Incomplete information causes delays and inaccurate price estimates.

Essential File Checklist

1. 3D CAD Model: STEP (.stp) is most universal and preferred format

2. 2D Engineering Drawing (PDF):
• Clearly call out all critical dimensions and tolerances
• Specify material and heat treatment requirements
• Specify all thread sizes and standards
• Indicate surface finish requirements
• Note required post-processing (anodizing, passivation)

3. Quantity: State quantities needed (10, 100, 1000 pcs) as quantity drastically affects unit price

Use this checklist before submitting RFQ. A professional "quote package" gets better pricing and establishes you as credible customer.
