Custom CNC Precision Steel Machining Parts
Steel Material Selection
Choosing the wrong steel grade is the #1 cause of premature part failure. Our engineers review your application before programming a single toolpath:
|
Application Need |
Recommended Steel |
Why It Works |
|
High strength & wear resistance |
42CrMo, 4140, 4340 |
Quench-and-temper ready, handles cyclic loads |
|
General structural & weldable |
Q235, 20#, A36 |
Cost-effective, good machinability |
|
Corrosion & hygiene critical |
304, 316, 316L |
Passivation compatible, food/medical safe |
|
High hardness tooling surfaces |
D2, O1, H13 |
Maintains edge integrity under abrasion |
We source certified raw material with full mill test reports (MTR) and verify composition via spectrometer before machining begins.
Precision Machining Without Compromise
Every batch follows a controlled workflow optimized for steel's unique properties-higher cutting forces, heat buildup, and tool wear compared to aluminum or brass:
|
DFM & CNC Programming |
We optimize toolpaths to minimize internal stress and deformation on thin-walled or long steel shafts. |
|
Multi-Axis CNC Turning & Milling |
Complex geometries, deep holes, precision threads, and tight flatness requirements handled in one setup. |
|
In-Process Inspection |
Key dimensions checked at 50% completion to catch deviation before finishing. |
|
Optional Heat Treatment |
Stress relief, quenching, or tempering performed per your mechanical spec to improve fatigue life. |

Finishing That Protects Your Investment
Raw machined steel rusts. We finish every part to match its operating environment:
- Vibration deburring for safe handling and clean assembly
- Black oxide / phosphating for indoor corrosion protection
- Zinc or nickel plating for outdoor and high-humidity exposure
- Passivation for stainless steel to restore the chrome-oxide layer

FAQ
|
Q1: |
I have a sketch but no formal drawing. Can you help? |
|
A1: |
Yes. Send photos, sketches, or samples. Our engineers convert them into production-ready 2D/3D files with tolerance recommendations. |
|
Q2: |
Do you stock raw steel, or does material sourcing delay production? |
|
A2: |
We maintain inventory of common grades (45#, 304, 42CrMo). Specialty alloys are sourced within 3–5 days. |
|
Q3: |
What is the sample lead time? |
|
A3: |
7–12 days for standard steel grades. Complex geometries or specialty materials may extend to 15 days. |
