Design Guidelines: CNC Turning
Our basic guidelines for CNC turning include important design considerations to help improve part manufacturability, enhance cosmetic appearance, and reduce overall production time.
|Length||0.25 in. to 0.030 in|
|Wall Thickness||0.020 in.|
6.35mm to 0.762mm
Typically, Proto Labs can maintain a machining tolerance of +/- 0.005 in. (0.127mm).

Live Tooling Capabilities
Our lathe machines contain live tools that allow additional milled features to be added to turned parts including flats, slots, and grooves. We can also add on-axis, axial, and radial holes to turned parts, but only support holes that are either parallel or perpendicular to the axis of revolution, and we cannot accommodate holes at odd angles.
Soft metals like aluminum and brass can be lightly bead blasted leaving a fine matte finish. Hard metals like steel and stainless steel can also be de-burred with a light bead blast which removes metal slivers and sharp or particularly rough areas.
|METAL||As-machined, deburred, or deburred with a light bread blast|
We currently support UNC and UNF threads from #2 up to 0.5 in., and metric threads from M2 to M12. Avoid modeling internal threads on your part design.
Sharp inside corners on a part will be radiused (rounded) as a natural result of the CNC machining process. Resulting radii will be identified before the part is milled. Turned outside corners will typically include a 0.005 in. chamfer.
