Pink CNC Machined Part

CNC Machining Services

CNC machining is used to control a range of complex machinery, allowing three-dimensional cutting tasks to be accomplished in a single set of prompts. Dedicated machine centers are ideal for high-volume production, short runs, test pieces, and prototypes. Over 90% of our customers’ castings require secondary die cast machining services through our CNC secondary machining centers.

Die Casting & CNC Secondary Machining Services

Custom casting is critical for providing good flow and fill characteristics for the die casting process while providing our customers with useful locating features and sufficient machine stock. If there's not enough machine stock within the initial design, you'll be scrapping parts after you've invested machining time into them.

The CNC Machining Process

The die cast part machining process must be considered well before any order for the tooling is released. A careful evaluation of machined requirements can lead to redesign for net shape die-casting or near-net shape with a reduced number of operations. SKS’ CNC machining services observe the following guidelines and parameters:

  • Complete date: 3D CAD models and 2D drawings, quantity, and all specs.
  • Tolerances with a focus on GD&T, flatness, porosity, and cosmetics.
  • Die Cast and Machining Datums.
  • Machining stock regardless of final tolerances and porosity specs.
  • Surface treatment, such as Powder Coating (PC) and Black Anodize, and tolerance impact.
    • Cast/machine/PC and masking or cast/PC (no masking) and machine.
    • Black Anodized with tolerances under 0.001" is hardly feasible to accomplish and has a different appearance compared with AL 6061 T6.
  • Dimensional and cosmetic Inspection criteria.
  • Parting line and moving mold components can affect dimensional tolerances.
  • Gate location and size in relation to porosity specs.
