How much does CNC machining cost?
CNC machining is a very effective solution for limited runs and lower quantity parts. Price depends on the material chosen, complexity, quantity, and required lead time. Prices for geometry manufacturable by CNC versus 3D printing are relatively comparable, but typically machining offers improved material properties and surfaces. The best way to find your exact price is to submit a 3D CAD model and get an interactive quote with design for manufacturability (DFM) feedback.
What types of threading options are available?
At all our fulfillment locations, we offer UNF, UNC, and metric threads. Our automated factory can machine parts for coil and key inserts without supplying or installing them. In our semi-automated factory and Protolabs Network, we provide the same threading options, plus SM1, SM2, and SM3 lens threads. We can also install hardware like standard coil inserts, key inserts, and heli-coils at these locations.
What is the maximum part size for CNC machining?
Maximum part size will vary based on your selected material. Our largest part size offered is 22 in. x 14 in. x 3.75 in. (559mm x 356mm x 95.25mm) and is available in Aluminum 6061 and 7075.
