CNC Machining FAQs
1. What is the typical cost of a CNC machined part?
Our engineering and sales teams will provide one-on-one quote support for your project. Typically, for similar parts, CNC lathes cost 15% less to machine than standard 3-axis CNC milling. In contrast, the cost of 5-axis machining increases, continuous 5-axis CNC milling typically costs over 20% higher than an indexed 5-axis machine (also referred to as 3+2 milling), and about double that of a standard 3-axis mill. To achieve the most cost-effective CNC machined parts, larger production runs are recommended to spread the cost of machine setup.
2. What is the typical lead time for CNC machined parts?
Lead times for CNC machined parts vary depending on factors like part complexity, material availability, and order volume. Generally, prototype parts can be delivered within 5-7 business days, while larger production runs may require longer. We strive to meet client deadlines and offer expedited services when possible.
3. What file formats do you accept for CNC machining projects?
We accept various CAD file formats, including STEP (.step, .stp), IGES (.iges, .igs), and STL (.stl). Providing detailed 2D drawings alongside 3D models is recommended to ensure accurate interpretation of dimensions and tolerances.
4. Do you offer finishing services for CNC machined parts?
Yes, we provide a range of finishing services to enhance the appearance and performance of CNC machined parts. Our offerings include anodizing, powder coating, bead blasting, and polishing. These finishes not only improve aesthetics but also add protective properties to the components.
