Before you send
the drawing.
Clear project details help us review your part quickly and give you a useful answer.
What kinds of CNC work do you quote?
We quote CNC turning, 3-axis milling, prototypes, short runs, repeat production, fixture work, and secondary operations. Challenging geometry and heat-treated materials are welcome.
What should I include with an RFQ?
Send a solid model and drawing when available, plus material, quantity, tolerances, finish requirements, and the date you need the parts.
