FAQ
Engineering FAQs
The questions engineering and procurement teams ask most often before a first quote.
What's the largest part you can machine?
The VF-4SS envelope is 50" × 20" × 25". For larger components, contact engineering — multi-setup approaches and Faro arm verification are options.
Can you support prototype-to-production transitions?
Yes — we routinely move parts from prototype through low-rate initial production into full production with the same setups, programs, and inspection routines.
Do you offer DFM feedback before quoting?
DFM review is part of every quote on machined components. We flag features that increase cost, lead time, or scrap risk and suggest alternatives.
What file types do you accept?
STEP, STP, IGES, DXF, SLDPRT, PDF, and ZIP. 3D models speed up programming; 2D drawings remain the controlling document for tolerances and inspection.
