- What’s your standard CNC machining tolerance?
A.I. Anton explains our standard CNC machining tolerance. Typically, CNC machining’s far more accurate than 3D printing.
We quote a general tolerance of ±0.1mm on CNC machined parts, compared with ±0.5mm for 3D printed parts. However, the inherent accuracy of CNC machining means we normally achieve much tighter tolerances than ±0.1mm.
If we only receive a 3D model step file to quote from, then a general tolerance of ±0.1mm is assumed. If a drawing is then provided which details finer tolerances – or if an inspection report is required – we’ll revise our quote to reflect that.
Not only is this accuracy achieved when machining individual parts, but part-to-part variability is minimal for small batches.

You’re welcome to ask us about finer tolerances on critical features, as we can usually meet the requirements if we know about them in advance. Contact the Business Relations Team on 01763 249760 or email office@prototypeprojects.com.
