Our CNC Machining Process: From Drawing Review to Delivery
Every CNC machining project follows a controlled process—from engineering review and production planning to machining, inspection, and shipping. This structured workflow helps us maintain consistent quality, predictable lead times, and reliable delivery.
1. Drawing Review & Quotation
We review your 2D drawings, 3D CAD files, materials, tolerances, surface finishes, and quantities before quoting. Our engineers check manufacturability and identify potential issues early.
What you get: Clear pricing, technical feedback, and a defined production plan.
2. Production Planning
Once the order is confirmed, we arrange materials, production capacity, machining schedules, and required processes based on your project requirements.
What you get: A clear production schedule and better control of lead times.
3. CNC Programming & Setup
Our engineers create machining programs and prepare the appropriate tools, fixtures, and machine setups according to your part geometry and tolerances.
What you get: Stable machining performance, fewer setup errors, and efficient material utilization.
4. CNC Machining & In-Process Control
Parts are machined using 3-axis, 4-axis, or 5-axis CNC equipment, depending on the complexity of the project. Critical dimensions are checked during production to identify deviations before they affect the entire batch.
What you get: Consistent dimensions and better batch-to-batch repeatability.
5. Full Quality Inspection
We inspect critical dimensions, tolerances, surface finish, and material requirements according to the order specifications. CMM and other precision measuring equipment are available for demanding parts.
What you get: Inspection data and confidence that your parts meet the specified requirements.
6. Final Quality Confirmation
Before packaging, finished parts undergo a final inspection to verify quantity, appearance, dimensions, and order requirements.
What you get: A final quality check before your parts leave our facility.
7. Protective Packaging
Parts are packed according to their material, size, surface finish, and fragility. Protective materials are used to reduce the risk of scratches, deformation, or damage during transportation.
What you get: Parts protected from the factory to your receiving location.
8. Shipping & Tracking
We coordinate shipping with your preferred logistics provider or arrange international delivery with tracking information. Shipment status is monitored through delivery.
What you get: Clear shipment visibility from dispatch to delivery.
