CNC Machining Services Overview

CNC machining, as a vital process within aluminum die casting, allows for precision machining and adjustments to aluminum castings to meet the final product’s requirements and specifications. In the aluminum die casting process, the aluminum castings obtained after aluminum alloy is injected into molds often require secondary machining and finishing to achieve the desired precise dimensions, shapes, and surface quality. This is where CNC machining comes into play.

Reliable & Versatile Die-cast Aluminum for Selection

Bian Diecast takes pride in offering a diverse spectrum of top-tier die-cast aluminum alloys to cater to a wide range of industrial demands. Our carefully curated selection encompasses three primary categories, each distinguished by its unique set of properties and applications.

CNC Milling

CNC milling workshop is equipped with milling machines used for flat milling, contour milling, hole drilling, and other operations. It is commonly employed in the production of parts such as flats, grooves, holes, and continuous threads.

CNC Turning

The CNC turning workshop features lathes used for rotational machining, including external contour machining, end-face machining, and thread machining. It is frequently used for processing components like shafts.

EDM Machining

Wire EDM machining, also known as wire-cut electrical discharge machining, is an electrothermal cutting process. Compared to traditional mechanical cutting methods, Wire EDM machining offers higher precision and surface quality, and it can handle more complex geometric shapes.
