Step-by-Step: How MQJM Produces China Precision CNC Milling Parts with Accuracy

Step 1: Design CAD Models

The CNC milling process begins with creating 2D or 3D drawings of the desired part using CAD/CAM software like Autodesk Inventor or SolidWorks. These tools allow you to specify dimensions and tolerance requirements.

Step 2: CAD Models to CNC Programs

Use CAM software to convert CAD models into G-code, executing necessary manufacturing operations, including cutting sequences, tool paths, speeds, and movements.

Step 3: Set Up CNC Machine and EMO

Insert the workpiece onto the CNC machine’s work surface, attach the cutting tool to the spindle, and download the G-code. Initiate the machining program, and the CNC machine will execute all necessary operations to process the workpiece.

Step 4: Inspection and Surface Treatment

After milling, inspect the part's accuracy and quality. Use additional processes like deburring, polishing, or surface treatment to meet the final product's requirements.



Quality Assurance from Leading China Custom CNC Milling Services Supplier

CNC product quality is maintained through three steps: pre-production, during production, and before delivery.



In pre-production, MQJM's procurement department strictly adheres to standards when acquiring raw materials. The QC team inspects 25% of these materials, and only qualified ones are processed. During production, technicians adjust CNC milling equipment and produce test parts for evaluation. Production proceeds only when test data meets criteria. The QC team inspects CNC millng parts every half hour, halting production for any discrepancies. Before delivery, QC personnel inspect the product's appearance, check for drilled holes, threaded components, and verify the assembly process. This ensures customers receive the products of CNC milling parts identical to the drawings. Custom CNC milling is a subtractive manufacturing process to produce a custom-designed part or product. Given the high precision and technical requirements of custom CNC milling services, implementing a robust QA process is essential for maintaining high standards of quality.
