Frequently Asked Questions
Common questions about our CNC milling services, capabilities, and processes.
What's the difference between 3-axis, 4-axis, and 5-axis CNC milling?
3-axis milling moves in X, Y, and Z directions for basic geometries. 4-axis adds rotational movement around one axis for cylindrical features. 5-axis provides simultaneous movement in all five axes, enabling complex geometries, undercuts, and complete part machining in a single setup with superior surface finish.
What tolerances can you achieve with CNC milling?
Our standard tolerance is ±0.005" (±0.127mm), but we can achieve precision tolerances down to ±0.0001" (±0.0025mm) for critical features. Tolerance capability depends on part geometry, material, and feature size. We follow ISO 2768 standards and provide detailed tolerance analysis for each project.
Which materials can you machine with CNC milling?
We machine a wide range of materials including aluminum alloys (6061, 7075, 2024), stainless steels (304, 316, 17-4 PH), carbon steels, titanium alloys, Inconel, brass, copper, and engineering plastics like PEEK, Delrin, and nylon. Material selection depends on application requirements, with full material certification provided.
What are typical lead times for CNC milled parts?
Lead times vary based on part complexity, quantity, and material availability. Simple parts can be completed in 3-5 days, while complex 5-axis components may require 2-3 weeks. We provide accurate lead time estimates during quoting and offer expedited services for urgent requirements.
What are your size limitations for CNC milled parts?
Our CNC milling centers can accommodate parts up to 60" x 40" x 24" (1524mm x 1016mm x 610mm). For smaller precision parts, we can work with features as small as 0.010" (0.25mm). We also handle both prototype single pieces and production runs up to 10,000+ parts.
What quality certifications do you maintain?
We maintain ISO 9001:2015 quality management certification and are working toward AS9100D aerospace and ISO 13485 medical device certifications. All parts include inspection reports, material certifications, and dimensional verification using CMM and other precision measurement equipment.
Do you offer secondary operations and finishing services?
Yes, we provide comprehensive secondary operations including anodizing, powder coating, plating, heat treating, assembly, and custom finishing. Our integrated approach ensures quality control throughout all processes and reduces lead times by eliminating multiple vendor coordination.
What file formats do you accept for CNC milling quotes?
We accept various CAD formats including SolidWorks (.sldprt), AutoCAD (.dwg), STEP (.stp), IGES (.igs), Parasolid (.x_t), and PDF drawings. 3D models are preferred for complex parts, but we can work from 2D drawings for simpler geometries. Include material specifications, tolerances, and quantity requirements.
How do you ensure part quality and consistency?
We implement comprehensive quality control including incoming material inspection, in-process monitoring, statistical process control (SPC), and final CMM inspection. All operators are trained and certified, machines are regularly calibrated, and we maintain detailed process documentation for traceability and continuous improvement.
How are CNC milling costs calculated?
Costs depend on material type, part complexity, machining time, tooling requirements, quantity, and tolerance specifications. We provide detailed quotes breaking down material, machining, setup, and any secondary operations. Volume discounts are available for production quantities, and we offer design optimization suggestions to reduce costs.
What are your packaging and shipping options?
We provide protective packaging appropriate for each part type, including custom foam inserts for delicate components. Shipping options include standard ground, expedited air freight, and white glove delivery for large or sensitive parts. Parts are inspected and documented before shipment with full traceability.
Do you provide design for manufacturability (DFM) feedback?
Absolutely! Our engineering team provides comprehensive DFM analysis to optimize your designs for CNC milling. We suggest modifications to reduce machining time, improve tolerances, eliminate potential issues, and reduce costs while maintaining functionality. This collaborative approach ensures the best possible outcome for your project.
