Design Guidelines for CNC Machining
|Maximum Part Size||
3 axis: 254mm x 178mm x 95mm
5 axis: 66mm x 73mm x 99mm
(Max size for Aluminium 559mm x 356mm x 95mm)
|Minimum Part Size||6.35mmx 6.35mm|
|Tolerances||Typically, Protolabs can maintain a machining tolerance of +/- 0.1 mm. Parts may be as thin as 0.5 mm in regions as long as nominal part thickness is above 1 mm. Maximum depth that can be milled is 50 mm from either side of part. For specific milling dimensions by material, see maximum part extents for machining.|
|Radii||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.|
|Text||• Recessed text should have a minimum stroke width of 0.5mm.
• The spacing between characters on raised text should be 0.5mm or greater.
• Minimum recessed text depth of 0.3mm.
• If design permits it, opt for recessed text versus raised.
Why Choose Protolabs for CNC Machining?
Advantages of CNC Machining
The subtractive process of CNC machining provides multiple benefits for both prototyping and low-volume production parts.
- Precision and repeatability
- Tight tolerances
- Production-grade materials
- Quick-turn parts within 1 day
CNC Machining Applications
CNC machining is widely used throughout the aerospace, medical, automotive industries for its ability to rapidly manufacture precise parts in production-grade materials. Typical CNC parts, include:
- Housings and enclosures
- Fixtures for manufacturing
- Gears and bearings
- Internal mechanical components
- Medical instrumentation
