How to Inspect Metal Spinning Parts

Spun parts quality checking requires a combination of methods to ensure that their dimensional accuracy, surface quality, mechanical properties, etc. meet the requirements. The following are common inspect methods and steps:On the other hand, CNC Spinning It also brings tangible benefits to everyone and feels useful. It is a model of the industry. https://www.richspinning.com/?spinningservice/

1. Appearance inspection (visual/optical inspection)

Surface defects: Check for cracks, scratches, wrinkles, peeling, oxidation and other defects.

Contour integrity: Observe whether the overall shape of the spun part is uniform, deformed or asymmetric.

Tools: magnifying glass, industrial endoscope, optical projector (for complex curved surfaces).

2. Dimension detection

Key dimensions: diameter, wall thickness, height, roundness, concentricity, etc.

Tools:

Caliper/micrometer: measure basic dimensions such as wall thickness and diameter.

Coordinate measuring machine (CMM): high-precision detection of complex surfaces and form and position tolerances.

Laser scanner: quickly obtain 3D contour data and compare CAD models.

3. Geometric tolerance detection

Roundness/cylindricity: used for rotating parts (such as cylindrical parts, tapered parts).

Coaxiality: detect whether the centers of different sections are aligned (such as missile shells, pressure vessels).

Flatness: suitable for flanges or end faces.

Tools: roundness meter, three-coordinate measuring machine (CMM), special inspection fixtures.

The inspection of spun parts needs to select appropriate methods according to their application scenarios (such as civil/military/aerospace). High-precision parts (such as missile casings, aircraft engine parts) usually require full-size inspection + non-destructive testing, while ordinary parts (such as lamps and decorative parts) may only require key size + appearance inspection.

Rich Metal have a complete QC system, we follow ISO 9001 manufacturing procedure and equipment with good measuring and test equipment, also have special QC and engineers to control the manufacturing procedure from prototyping to delivery.
