Custom CNC Milled Parts

Core Advantages

Coordinated Mating Dimensions

Linear dimensional tolerances of ±0.02–±0.03 mm support controlled fit between adjoining features. In a locating block that contacts a machined shoulder, limiting variation in those dimensions preserves the clearance assigned by the assembly design rather than leaving the fit to nominal dimensions alone.

Fewer Setup Transfers

Milling, drilling, reaming and tapping can be combined for features accessible from the same setup. When a component carries both a locating face and a fastener pattern, machining them against one reference reduces the number of transfers that can affect their relative positions.

Material Options Beyond Metal

Engineering plastics are available alongside metal substrates. In an assembly that requires an insulating spacer or a nonmetallic contact piece, machining the specified plastic grade provides the required shape without introducing a metal contact at that interface.

Customization Capabilities

Production starts from the agreed drawing or sample definition. We review tool access and the machining sequence, confirm any proposed geometry changes before cutting, and use the approved version for both the initial parts and the subsequent production run.

Quality Control

Material identity and stock condition are checked before release to the workshop. Machining and inspection use the same drawing revision, including the dimensional callouts that are not fully represented by the solid model.
First-article measurement confirms the setup before production continues. A coordinate measuring machine checks drawing-defined locations and face relationships, while in-process sampling monitors dimensions affected by tool wear or a setup change.
Final inspection includes every part before packing. Dimensional results, finish condition and part identification are checked against the order; inspection records remain associated with the production lot for later queries or third-party verification.
