CNC Prototyping and CNC machining

CNCA few benefits of CNC Machining or milling rapid prototypes: many choices of real production materials, along with good accuracy and durability.

We deliver the benefits of CNC machining at a very competitive price point with lead times of typically 5 to 7 calendar days or less. ABS parts and aluminum parts are the most popular and cost effective solutions for prototyping.

Most CNC machining or prototypes only requires 3 axis milling or turning. In some instances, where the part size is large, stock sizes are insufficient or complexity prohibit accessibility, it is necessary to combine machining with fabrication. In these instances, parts are assembled and dressed so no apparent indication of fabrication is visible.

Minimum CNC Feature Size
This is a function of geometry as it is also related to cutter reach and feature location. Preferably the smallest cutters used would be 1 mm, leaving a 0.5mm internal radius. However 0.2 mm cutters can be used if required.

Bed Sizes
Bed sizes up to 24"x 36" x 7" are readily available with access to larger machines as required.

Finish
The parts may be supplied in a natural state, it is more common to supply parts dressed and primed ready for a final painted topcoat, or fully finished with texture/gloss finish.
