Alloy steel
Alloy steel provides high strength, excellent toughness, and superior wear and corrosion resistance. It performs reliably under extreme temperatures and can exhibit magnetic properties, making it ideal for industrial and structural applications.
Custom CNC Turning Finishes
We offer one-stop surface finishing for custom CNC-turned parts, including sandblasting, anodizing, electroplating, baking, passivation, polishing, blackening, and QBQ protection. Professional testing ensures film thickness, hardness, color, corrosion resistance, and adhesion meet strict standards—delivering reliable, high-quality, and visually excellent components.
Electroplating
As machined finish leaves the surface straight from the CNC machine, providing a cost-effective option with tool marks.
Anodizing
Enhances corrosion resistance and surface hardness while adding color for improved durability and appearance.
Polishing
Polishing achieves a high gloss finish, reducing surface roughness and enhancing the aesthetic appeal of metals.
Sand Blasting
Sand blasting uses pressurized sand or other media to clean and texture the surface, creating a uniform, matte finish.
Tumbling
Tumbling smooths and polishes small parts by friction and abrasion in a barrel, offering a consistent but slightly textured finish.
Electropolish
Electropolish is a chemical process that smooths and brightens surfaces while improving corrosion resistance.
Alodine
Alodine coating provides corrosion protection and improves paint adhesion, mainly used on aluminum surfaces.
Electroplating
Electroplating bonds a thin metal layer onto parts, improving wear resistance, corrosion resistance, and surface conductivity.

What is CNC Turning?
CNC turning is a precision machining process in which a cylindrical workpiece is clamped in a chuck and rotated at high speed while a cutting tool moves along the X and Z axes to remove material and form the desired geometry. Controlled by CAD/CAM programming, the process supports operations such as facing, threading, drilling, and grooving, enabling high dimensional accuracy and repeatability. Coolant is applied to maintain temperature stability and ensure consistent cutting performance. After machining, parts undergo deburring, inspection, and optional surface finishing to meet customer specifications. CNC turning is widely used for producing shafts, pins, fittings, connectors, and other rotational components across industrial applications.
