Materials Available for Turning
From general-purpose metals to high-performance engineering plastics, matched to your part's mechanical and environmental requirements.
Aluminum
Lightweight with excellent machinability, ideal for prototypes and structural components.
Stainless Steel
Corrosion-resistant and durable, suited to medical, food, and marine applications.
Steel
High strength and wear resistance for structural and mechanical parts.
Brass
Excellent machinability and conductivity, common in fittings and electrical components.
Copper
High electrical and thermal conductivity for connectors and heat-transfer parts.
Titanium
Exceptional strength-to-weight ratio and biocompatibility for aerospace and medical parts.
Surface Finishes & Post-Processing
Functional and cosmetic finishing options applied after turning, matched to your part's material and end use.
As-Machined (Standard)
The standard finish directly off the lathe, functional and cost-effective, with visible tool marks.
Bead Blasting
A uniform matte, satin texture achieved by blasting the surface with fine glass or ceramic media.
Anodizing (Type II & III)
Electrochemical coatings that improve corrosion resistance and wear resistance, with Type III (hardcoat) suited to high-abrasion applications.
Black Oxide
A thin conversion coating that provides mild corrosion resistance with minimal dimensional change.
Plating
Electroplated finishes for improved corrosion resistance, wear resistance, or conductivity.
Polishing
Mechanically polished to a smooth, reflective surface for cosmetic or low-friction applications.
CNC Turning vs. CNC Milling
Turning is suited to cylindrical, axially symmetrical parts, while milling is suited to blocky, non-symmetrical parts. BSG helps you choose the right process for your geometry.
| Feature | CNC Turning | CNC Milling |
|---|---|---|
| Part Geometry | Cylindrical, axially symmetrical parts | Blocky, non-symmetrical parts with complex features |
| Workpiece Motion | Part rotates against a stationary cutting tool | Tool rotates while the part remains stationary |
| Typical Parts | Shafts, pins, bushings, fittings, fasteners | Brackets, housings, plates, enclosures |
| Best For | Round or tubular profiles | Flat faces, pockets, and angular features |
| Achievable Tolerance | Down to ±0.005 mm on diameter | Down to ±0.01 mm on position/flatness |
