Design for CNC Machining (DFM)
Optimize your part design for manufacturability, cost efficiency, and lead time reduction.

Standard DFM guidelines optimize part geometry for CNC production
Recommended Wall Thickness
Minimum 0.8mm for plastics, 1.0mm for aluminum, 1.5mm for steel
Corner Radius Guidelines
Minimum R0.5mm internal corners; larger radii reduce machining time
Hole Depth-to-Diameter
Maximum 4:1 ratio for standard drilling; up to 10:1 with special tooling
Thread Design Best Practices
Allow 1.5× diameter engagement; avoid blind hole tapping where possible
💡 Cost Reduction Tips
Standard tolerances, fewer setups, common materials, and avoiding undercuts

Frequently Asked Questions
What tolerance can CNC machining achieve?
Standard production holds ±0.02mm tolerances. For critical features, we can achieve ±0.005mm precision with appropriate fixturing and inspection protocols. All precision parts include full CMM dimensional reports.
What materials can be CNC machined?
We regularly machine aluminum (6061, 7075), stainless steel (304, 316L), titanium (Ti6Al4V), brass, copper, and engineering plastics including PEEK, ABS, PC, and Nylon. Specialty alloys available upon request.
What is the minimum order quantity?
There is no minimum order quantity. We accept orders starting at 1 piece for prototypes and single-part requirements. Pricing becomes increasingly competitive at volumes of 50+ pieces and above.
How fast can CNC prototypes be delivered?
Standard prototype lead time is 3-7 working days for aluminum and plastic parts. Titanium and stainless steel prototypes typically ship in 7-10 days. Expedited 3-day service is available for urgent projects.
Can you machine titanium and other difficult materials?
Yes. We have extensive experience machining titanium, Inconel, Hastelloy, and other high-performance alloys. We use specialized carbide tooling, optimized speeds and feeds, and coolant strategies for these challenging materials.
Do you provide CMM inspection reports?
Full CMM inspection reports are available upon request for any order. We operate coordinate measuring machines with micron-level accuracy and can provide dimensional layouts, first-article inspection reports (FAIR), and material certification documents.
Can you support production quantities?
Absolutely. We scale seamlessly from single prototypes through low-volume production (10-500 pieces) up to medium-high volume production runs (500-10,000+ pieces). Dedicated production cells are established for ongoing programs.
What CAD file formats do you accept?
We accept STEP, IGES, SolidWorks (SLDPRT), Parasolid (X_T), and STL files. PDF drawings with critical dimensions and tolerance specifications are also appreciated. DXF files work for 2D profiles and sheet metal parts.
What surface finishes are available?
Standard as-machined finish is Ra 1.6-3.2μm. Available options include: bead blasting, anodizing (Type II/III), chromate conversion, passivation, electropolishing, powder coating, and various plating options.
Do you offer design for manufacturability (DFM) feedback?
Yes. Our engineering team provides complimentary DFM analysis on every quote. We identify potential cost-saving opportunities, tolerance optimization, and feature modifications before production begins—no charge for this service.
