Getting the Best Quote from CNC Machining Shops
Practical tips for preparing RFQs, comparing quotes, and negotiating with CNC machining shops to get the best value.
Preparing Your RFQ Package
A well-prepared RFQ gets you better quotes, faster. Include 2D drawings (PDF) with GD&T callouts, 3D models (STEP or IGES format), material specifications, surface finish requirements, quantity and delivery schedule, and any required certifications or testing. The more detail you provide upfront, the more accurate your quotes will be.
What Drives Pricing
Key cost factors include material type and grade, part complexity and number of setups, tolerance requirements (tighter tolerances = higher cost), surface finish specifications, quantity (higher volumes reduce per-unit cost), required certifications, and lead time (rush orders cost more). Understanding these factors helps you optimize your design for manufacturability and cost.
Comparing Quotes Effectively
Don't just compare bottom-line prices. Look at what's included: material costs, setup charges, inspection and testing, packaging, and shipping. Ask about payment terms, minimum order quantities, and blanket order options for recurring needs. A slightly higher quote from a more capable supplier often provides better value through reduced scrap, fewer quality issues, and faster delivery.
