Our basic guidelines for CNC turning include important design considerations to help improve part manufacturability, enhance cosmetic appearance, and reduce overall production time.

| LENGTH | 1.27mm |
| WALL THICKNESS | 0.51mm |
| ANGLE | 30° |
Small features may be allowed, but the diameter in any region should not be less than 0.030 in. (0.76mm). Sharp conical points are allowed; angles should be greater than 30 degrees. Walls thinner than 0.020 in. (0.5mm) typically do not survive the machining process. For specific turning dimensions by material, see maximum part extents for machining.
Typically, FacFox can maintain a machining tolerance of +/- 0.005 in. (0.13mm).
