Capabilities
CNC Machining Services Built for Your Needs
We support RFQ-based buying with CNC milling, CNC turning, prototype development, low-volume production, and surface finishing for industrial hardware, equipment builds, and engineered parts.
CNC Turning
Turning support for shafts, spacers, pins, bushings, and cylindrical components used in assemblies, jigs, and machines.
Prototype Machining
Functional prototypes and engineering samples to validate fit, assembly, and real-world application before scaling volume. 1-piece MOQ, 3–5 day lead time.
Low-Volume Production
Suitable for pilot builds, early market demand, service parts, and steady repeat orders where reliability matters most.
Surface Finishing
Anodizing, polishing, sandblasting, plating, and post-processing support depending on cosmetic and functional requirements.
Drawing-Based Work
We quote from STEP, STP, DWG, DXF, IGES, and PDF files with attention to material, quantity, finish, and critical callouts.

Quality
Inspection & Quality Control
Our Process
Parts you can trust
Every order goes through dimensional inspection before shipping. We use CMM, digital calipers, and gauging tools to verify critical dimensions against your drawing requirements.
- CMMCoordinate Measuring — CMM inspection for complex parts with tight tolerances and GD&T callouts.
- DIMDimensional Verification — All critical features checked against drawing dimensions before shipment.
- SFCSurface Finish Control — Ra measurements and visual inspection for cosmetic and functional surface requirements.
- PKGProtective Packaging — Parts wrapped and packed to prevent damage in transit to your U.S. address.
