Precision CNC Machining Services | BXD

BXD provides a variety of precision CNC machining services including milling, turning, EDM (electrical discharge machining) and wire EDM, surface grinding, laser engraving and much more. With our precision 3-, 4- and 5-axis CNC machining centers, combined with other advanced capabilities and our experienced team, we can provide prototypes and small volume machine parts in tight lead time and high quality, so your team can focus on bringing your product to market.

CNC can machine a wide range of materials to meet your needs (ceramic, plastic, wood, metal, composite, foam and glass), and can be used across a wide array of industries. We also offer a lot of second machining and surface finishing service, such as painting, silk printing, brushing, plating, polishing, sandblasting, anodizing and so on. At BXD, our CNC machining process is widely applied in new product development, rapid tooling, product prototyping and end-product manufacturing.

If you need a precision machining company for plastic and metal CNC machining parts, BXD is the best place to go.

CNC machining manufacturer - BXD

What is CNC Machining?

The term CNC widely refers to the “computer numerical control” technology that is used in the subtractive manufacturing process. CNC machining is a manufacturing technology involving the use of computer-aided controls and machine tools to remove layers/portions of a stock material/workpiece till a desired custom and final part is made from the workpiece.

CNC machining - Milling (3-, 4- & 5-axis)

CNC lathe- Turning machine

Wire EDM

Laser marking

Surface finishing

The surface treatment process involves clear anodize, black anodized, passivation, clear chromate conversion, clear anodize, electroplating, high speed sand blasting, high polished, deburring, smooth, superficial wiredrawing, etc.


The surface finishing types include: rose gold, gun color, chromium, nickel, etc.

Our surface treatment performance tests can meet or exceed industry standards.

These are the most common materials for CNC prototyping and production parts.  If the desired material is not listed above, please contact our team. 


EDM / Wire EDM and Surface Grinding

-Electrical discharge machining (EDM) is an essential manufacturing process used primarily on tool steels for plastic injection molding or pressure die casting. EDM uses a conductive graphite or copper electrode submerged in a dielectric bath of water or oil. When a high voltage current is applied to the electrode it sparks against the tool wall, etching away at the surface to produce deep holes, ribs, undercuts and surface textures that are difficult to machine conventionally. When done properly, EDM can produce excellent surface finishes with tight tolerances, virtually eliminating the need for secondary polishing.

-Surface grinding is an automated machining process used to make extremely flat and smooth surfaces. In this method, the workpiece is held in a fixture and then reciprocated across the face of a precision grinding wheel.
