How to Inspect & Investigate Precision Machined Components? | Junying Precision CNC Machining

– For small batch production, use the micrometer to inspect the dimensional precision of the CNC machined part.

– For large volume production, a plain restriction gauge can be used for inspection. 

– For precision components with large length and high precision, we can use comparators. 

– If there are high requirements for the surface roughness, use the optical microscopes or contour graph.

– It is able to additionally use micrometer with V shape iron to degree.

– About the deviation from cylindrical shapes, we can use a micrometer to measure the difference between the max and min size of the identical axial phase.

– The inspection of mutual positional precision of most important shaft always use of the center hole on both ends of the shaft as datum reference, measuring with micrometer gauge on each bearing magazine.
