After the completion of titanium alloy CNC Machining, a series of quality inspections are required to ensure machining quality and accuracy. These tests include: 1. Dimensional accuracy testing: checking whether the actual dimensions of the workpiece meet the design requirements. 2. Surface quality inspection: Check whether the surface of the workpiece is smooth, free of scratches, cracks, etc. through visual inspection, surface roughness measurement, and other methods. Geometric shape detection: Check whether the geometric shape of the workpiece meets the design requirements, such as angles, radians, etc. 4. Hardness testing: For titanium alloy workpieces that require hardness testing, appropriate hardness testing methods should be used for testing. 5. Non destructive testing: using non-destructive testing techniques such as X-rays and ultrasonic waves to inspect whether there are defects or problems inside the workpiece. 6. Mechanical performance testing: Conduct mechanical tests such as tensile, compressive, and bending on titanium alloy workpieces to evaluate whether their mechanical properties meet the design requirements.
