I will machine cnc prototypes with dfm review for robotics and hardware startups
Grant Lv
About this gig
I review your CAD for manufacturability before machining CNC prototypes (110 pcs) for robotics and hardware teams catching costly design issues before you commit to a batch, not after.
This is for early-stage engineering: your design is still being tested and iterated on, not yet locked for production.
DFM review includes:
- Feasibility check on your geometry, tolerances, and features
- Flagging costly-to-machine details before cutting
- Material and finish recommendations
Typical parts I work on:
- Robotics structural components
- UAV mechanical parts
- Enclosures and functional prototypes
Capabilities:
- Rapid CNC machining for small batches
- Engineering-fit focused machining, not just cosmetic parts
- Materials: aluminum, stainless steel, plastics
- Standard tolerances of 0.02mm to 0.05mm, tighter available on request
- Prototype turnaround: 5 to 10 business days, depending on part complexity and quantity
Send your STEP file or basic dimensions to get started.

I’m a CNC Manufacturing Engineer with 10+ years of experience in precision machining, prototyping, and supplier management in China.
I help startups, product developers, and hardware teams turn CNC designs into manufacturable parts while balancing cost, quality, and lead time.
My work covers DFM review, supplier evaluation, prototype sourcing, quality inspection, and production coordination.
I can review STEP/STP files, technical drawings, materials, tolerances, and finishing requirements before production, and flag potential manufacturing issues early.

FAQ
Can you manufacture my parts?
Yes — I machine prototype and low-volume batches (1–10pcs) directly. For production runs above that (100–2000pcs) with full supplier coordination, see my dedicated production scaling Gig.
What file formats do you accept?
STEP, STP, IGES, X_T, DWG, DXF and PDF drawings.
Do you support robotics projects?
Yes. Robotics, UAV, automation equipment, fixtures, sensor mounts and custom hardware are my primary focus.
