CNC Milling

Computer Numerical Control (CNC) prototyping is a cutting process in which material is removed from a block by a rotating tool. In CNC milling the cutting tool is moved in all three or five (diagonal movement) dimensions to achieve the desired part shape. In CNC milling the cutting tool usually rotates about an axis that is perpendicular to the table that holds the material to be cut. A milling machine looks somewhat like a drill press at first glance. A cutting tool protrudes down from a rotating spindle. A block of material is placed on a moving table below the cutter. While the cutting tool turns, a computer controls the diagonal (Z axis) motion of the cutter and the horizontal and vertical (X and Y axis) motion of the block of material. The cutter is guided to move through the material, removing small portions to create the final shape. We are specialized in CNC milling. This technology gives the most accurate presentation of a mass production part

How to make a CNC prototype

  1. To make a CNC prototype, we need a 3D drawing, material information and the surface requirements.
  2. Our CNC manufacturing department selects a block of the required material and programs the CNC machine according the 3D drawing. In the whole process, the CNC machine needs to change size cutters according to the different radiuses in the 3D drawing.
  3. After the CNC machining, the preliminary shape will come out. After that we clean the corners and edges, and we measure if the dimensions are according the 3D drawing.
  4. After the initial dimension checks we will polish the CNC parts and wash it, there is again a dimension check for the 3D prototype.
  5. After CNC machining and dimension checking, we sent the parts for surface treatment finish, according to your specifications. We offer many different treatment finishes.
  6. In the end there is a final Quality control and we will send a dimension report and pictures to our client for confirmation.

Different materials and surface treatments

We can process many rigid materials including most metals: Aluminium, Stainless Steel, Copper, Steel, Brass, Titanium, Sterling Silver, Bronze, etc. 
Hard plastics and other materials are suitable for CNC machining as well: Nylon, Acetyl, Polycarbonate, Polystyrene, Acrylic, Fiberglas, Carbon fiber, PTFE, ABS, PVC, etc. 
We can apply many different surface treatments, such as: Painting, sandblasting, polish, silk-print, anodize, chroming, transparent surface, translucent surface, brush, rubber oil and electroplating.
