Our CNC Turning Capabilities

Based on a 1500 square meter workshop and over 80 experienced CNC Machining experts, STCNC handles simple parts in bulk and has extensive experience in machining complex parts. With our Powerful Capability and Partner Network, we can Finish your parts in a quick turnaround to your requirements with Tight Tolerance.

CNC Lathing&Turning, Turning&Milling Compound Machining

A CNC Lathe uses a rotating workpiece while a cutting tool moves along the material to create a shape—they usually process Simple cylindrical geometrical parts. We used CNC Turning Machine with live tools that can make more complex geometrical components. STCNC has Milling-Turning Compound Machines capable of performing both milling and turning operations on a single workpiece without requiring multiple setups, which can save time and increase accuracy.

Available Surface Finishing

Anodize

Anodizing is an Electrochemical process that converts the metal surface into a Decorative, Durable, Corrosion-Resistant, Anodic oxide finish.

Powder Coating

Powder Coating adds a thin layer of Protective Polymer on the surface of the Parts.it is a Strong Wear Resistance finish that is Compatiable with all Metal. Custom Color available.

As Machined

It is the Standard finish of our Parts. The “As Machined “has a roughness of 3.2 micrometers (126 micro inches). We Removed all sharp edges and burrs.

Brushing

Parts are Brushed with Sandpapers #400-600 grit, which results in a Unidirectional Satin, a Finish Mostly used for Aesthetic Purposes.

Black Oxide

Black Oxide is one of the Conversion Coatings often used on steel. It can improve Corrosion Resistance Performance and reduce light reflection.

Bead Blasting

Part is Blasted with tiny glass beads using a Pressurized Air gun, which removes the Machine Marks and Adds a uniform matte and Texture to the Parts.
