China high-quality precision CNC milling services you can trust. Competitive pricing and fast lead times.
CNC Milling is a subtractive manufacturing process that uses computer-controlled machines to remove material from a block (known as a blank or workpiece) and shape it into a finished part. The process begins with a CAD model, which is then converted into a CNC program and set up in the CNC machine.
CNC stands for Computer Numerical Control milling. This means that the milling machine is moved and monitored by numerical computer control rather than by hand. CNC milling tools perform a machining process similar to drilling and cutting parts with incredible precision, leaving no room for human error.

HKAA offers a wide variety of materials for custom CNC machining, plastic, and metal, including but not limited to:
HKAA Machining offers a wide selection of surface finishes to improve the surface qualities of CNC-turned parts. The surface finishes applied after machining can change the appearance, surface roughness, hardness, and chemical resistance of the produced parts.
This finishing option with the shortest turnaround time. Parts have visible tool marks and potentially sharp edges and burrs, which can be removed upon request.
Smooth machining is similar to a ‘As machined’ finish, but with less visible machine marks. Parts are machined at a lower feed rate, with no hand polishing.
Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment.
Machined parts are bead blasted with glass beads which results in a uniform grainy texture and reduced machining marks.
It is a process that tumbles vibrating media on machined parts to remove sharp edges and burrs. Tumbling can be used to remove machine marks from exterior surfaces.
The parts are bead blasted to #120 grit before being anodized type II—ideal for increasing the aluminum part’s corrosion resistance and cosmetic effects.
The parts are bead blasted to #120 grit before being anodized type III. Type III (Hard Coat) is thicker and adds a wear-resistant layer to Type II’s corrosion resistance, suitable for functional applications.
Black oxide is a conversion coating that is used on steels to improve corrosion resistance and minimize light reflection.
