The workable tolerances for machining purposes can be 20-50 microns.

CNC Turning | Machining Design Guidelines 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 ...

Plastic Fabrication & Machining Guidelines | Boedeker However, the relative softness of plastics (compared to metals) generally results in greater difficulty maintaining tight tolerances during and after machining. A good rule of thumb for tolerances of plastic parts is +/- .001 per inch of dimension although tighter tolerances are possible with very stable, reinforced materials.
