CNC Machining metal parts
Aluprototyping  offers CNC machining process to include aluminium, zink, brass, stainless steel, steel. Several surface treatments are available.

CNC Machining Design Guidelines
CNC machining via the Aluprototyping machining process produces functional parts from solid blocks of real metal. Read on to learn more.

Designing for the Aluprototyping Machining Process
Unlike additive processes that can create geometries of almost unimaginable (and, unfortunately, un-manufacturable) complexity, subtractive rapid prototyping is limited to shapes that can be cut out of a block of solid material using CNC milling machines.

Part Size 
At this point in time the Aluprototyping prototype process uses CNC mills capable of producing parts.Parts smaller than 5 x 5 x 5 mm are (really) hard to hold on to while machining.

Part Complexity
The Aluprototyping process is currently limited to 3-axis milling from 6 perpendicular sides. We mill from one side and rotate the part 90 degrees or 180 degrees as necessary to mill as many features as possible.Sharp inside corners on a part will be radiused as a natural result of the CNC milling process. 

Very small features, particularly if they are deep, may not be machinable. Recessed text should have a minimum stroke width of 2 mm. If any features cannot be machined, we can do additional EDM or we will discuss with you alternatives.

Threaded Holes
Aluprototyping now offers threaded holes. This information must be indicated in a 2D drawing.

Wall Thickness
CNC machining can produce very thick walls without sink or warp and there is no requirement that wall thicknesses be uniform. Walls thinner than 1 mm typically do not survive the machining process.

Tolerances
Tolerances of +/- 0.05 mm are expected and generally achieved. There is no provision within the Aluprototyping process to tweak any dimensions.
