FAQ
Frequently asked questions
+What’s the largest part you can machine?
Oversized work is our specialty — the parts that won’t fit or hold at other shops. Call with your dimensions and we’ll tell you straight whether we can handle it.
+What materials do you work with?
Steel, cast iron, aluminum and a wide range of alloys — for turning, boring, milling, welding and fabrication.
+Do you do one-off parts or only production runs?
Both. From a single oversized part to full high-volume CNC production, on the same shop floor.
+How tight are your tolerances?
We machine to your print. Send the drawing and we’ll confirm the tolerances we can hold.
+Can you repair or rebuild existing equipment?
Yes — machine repair and rebuilds to get your equipment operational and safe, and we’ll work after-hours when a line is down.
+How do I get a quote?
