CNC Machining – Express

Milling

Your part needs to fit into one of these billet sizes:

• 150mm x 50mm x 40mm
• 100mm x 100mm x 80mm
• 100mm x 100mm x 40mm
• 100mm x 50mm x 40mm
• 50mm x 50mm x 40mm

Parts can be made from:

• Aluminium 6082
• Acetal (black and natural)
• Clear Acrylic

Turning

• 60mm max dia in Aluminium 6082
• 60mm max dia in Acetal (black and natural)
• 60mm max dia in Clear Acrylic
• 60mm max dia in Stainless Steel (316/304)

Numerous types of metal and plastic material can be machined using CNC machining. We keep a stock of commonly used materials in-house. Only the materials listed below, are available on our CNC Express service. If you require different materials, you will need to choose one of our other CNC service levels.

• Acetal – black and natural
• Acrylic – clear
• Aluminium – 6082

All machined parts are vapour blasted, as standard. Other finishes are available on request, but will need to be ordered using one of our other CNC service levels.

Threaded holes of M2 – M12 (model drill hole size) are supported on our CNC Express service. Standard threads only. For through tapped holes make hole size suit drill Ø M1-M12. See the diagram below for details.

Drill depth clearance for blind holes:

As a natural result of the CNC machining process, the sharp inside corners of a part will be rounded (radiused). The resulting radii will be identified before the part is milled as this will depend on the depth of the feature.

Sharp corner concession:

Here are some considerations, should your part incorporate text:

• 0.5mm is the minimum stroke width for recessed text
• 0.5mm, or greater, spacing should be used between characters on raised text
• Recessed text is better than raised text

• General machining tolerance: ±0.1
• Hole tolerance: H7
• Number of items and quantity of limited (geometry specific)
• Maximum of five separate parts may be included in one quote request
• Inspection: basic visual to CAD
