CNC Machining Parts

1. What is CNC machining?

CNC (Computer Numerical Control) machining workpiece is a part processed by computer numerical control machine tools (such as milling machines, lathes, machining centers) for high-precision cutting, drilling, boring and other materials of metal, plastic. CNC technology enables the automatic production of complex geometric shapes by digitally programming the tool path.

3.why do we need to combine CNC machining with forging?

Forging advantages: The forging process can optimize the organization of the metal, and improve strength, toughness, fatigue life (such as wind power flange, engine parts).
CNC machining advantages: provide high precision, complex surfaces (such as pins and pin holes, bolts and nuts).
✅ Improve performance: forging to ensure the mechanical properties of the matrix, CNC machining to ensure the assembly accuracy.
✅ Cost reduction: forging close to Net Shape (Near-Net shape), reduce CNC machining allowance.
✅ Shorten cycle: avoid material waste and man-hour consumption of pure machining.
✅ tolerance high precision: tolerance up to ±0.005mm, mainly concentricity, coaxial, position to meet the needs of precision assembly.
✅ Complex shape: can be processed 3D surface, (such as alloy joints, impeller).

✅ A wide range of materials: suitable for metal (steel, aluminum, copper, alloy).

4. Key quality control measures in Weforging:

4.1 Dimensional detection: Coordinate measuring machine (Mitutoyo), optical profilometer.
4.2 Surface treatment: Dacromet, chrome plating, sand blasting, phosphating, galvanized.
4.3 Material testing: Provide the original material report (such as ASTM, ISO standards).
4.4 Measuring tool testing: Regular third-party testing.
4.5 Whole process inspection: first inspection, three coordinates, inspection, final inspection.
4.6 Mazak machining process monitoring: real-time tool wear detection, and the first part of the Mitutotyo coordinate synchronous detection of comparative data, adjust the program parameters to prevent machining deviation.
4.7 Sample and small batch inspection: After the three-coordinate test, the customer confirms and tests twice to confirm the testing standards of both sides!
