FAQ's
1. How long does a typical CNC turning process take?
The duration of a typical CNC turning process varies based on factors such as part complexity,
material type, tolerances, and machining operations. It can range from minutes to hours.
For projects with time constraints, lead times as short as 5 days.
2. What are your tolerances for machined parts?
Our tolerances for machined parts are typically within +0.005"/-0.005" for most metal geometries,
and within +/- 0.010" for plastics. However, tolerances may vary for larger parts, especially when
maintaining flatness over extensive sections post-heat treatment.
Regarding the finish requirements, an "As Milled" finish should have a minimum of 125 surface
finish for CNC parts.
For all fabricated parts, there is a dimensional tolerance of 0.010" and an angular tolerance of 1°.
Please note that tapped holes not explicitly indicated as features in the provided CAD model
may be machined to the specified diameters in that model.
Additionally, surface treatments like anodizing, bead blasting, iriditing, powder coating, etc.,
will only be applied if they have been paid for and explicitly acknowledged in advance.
