What surface finish is achievable on 1117 Steel with CNC Turning?
Surface finish on 1117 Steel is controlled to your specification; we confirm the achievable Ra against your callout.
Does CNC Turning 1117 Steel require dedicated tooling?
Most 1117 Steel turning work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
Why is 1117 Steel a good choice for CNC Turning?
1117 Steel is strong, economical and widely available, which makes it well suited to CNC Turning. We tune the process to the alloy so the finished 1117 Steel turning part meets your dimensional and functional requirements.
What tolerances can you hold for CNC Turning 1117 Steel?
Achievable tolerances for 1117 Steel turning depend on the alloy, geometry and feature size. Turning holds diameter tolerances to around ±0.005 mm with concentricity within 0.01 mm. Exact figures are confirmed against your drawing callouts.
Can VT machining make custom 1117 Steel parts to my drawing?
Yes. 1117 Steel turning is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
