Rapid CNC Machining
CNC machining is ideal for prototype parts that need functional testing using final production materials. At 3ERP, we operate a broad range of CNC machining centers, including mills and lathes (for CNC turning), enabling fast and reliable production. We support a broad selection of materials and finishes, and can also combine CNC machining with other processes for greater flexibility.
CNC machining is one of the most precise fabrication methods available. While it prioritizes quick turnaround over ultra-tight tolerances, the output quality remains high.
CNC machining offers fast turnaround for small-batch production, producing parts that are often nearly production-grade. Although typically more expensive than 3D printing, CNC parts provide an excellent surface finish and superior mechanical strength.

Surface Finish and Post-Processing Options
As machined
The machined or deburring finish is the standard finish where unwanted attach chips are removed with deburring tools, and sharp edges are chamfered to smooth the surface (3.2 μm).
Bead Blasted
Bead blasting produces a matte texture, removing all the marks of machining tools. It applies to ABS, Aluminum, Brass, Stainless Steel, and Steel parts.
Anodizing
Anodizing involves adding an aluminum oxide coating to aluminum and its alloys. The layers, which come in various colors, increase strength and shield the surface from corrosion.
Alodine
Provides excellent corrosion resistance property to the aluminum parts with greenish-gold color. It is the low-cost and quick surface finishing approach.
Polishing
Physical rubbing of a metal surface to create a shiny surface is called a polishing surface finish. It increases the reflectivity and does not affect the dimensional stability of parts.
Brushing
Brushing is achieved by applying an abrasive brush to the metal surface, which produces a unidirectional satin finish. And it is not recommended for highly corrosive materials.
