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

2018.11.17

The precision machined components should be inspected after manufacturing, to check out if they are qualified and precise. The precision parts often have a complex structure and unique shapes, need to be measured in multiple steps. Junying will introduce how to inspect and investigate the components and precision CNC machining services. 

How to Inspect Precision Machined Components? - Precision Components Inspection Tips

– 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.

Precision Components Operation Requirements

1. Establish a series of practical and effective operation rules and instructions in the use and management of CNC machine tools.

2. In order to extend the service life of CNC equipment, it’s necessary to avoid direct sunlight and other thermal radiation, too humid space, and space with too much dust and corrosive gas. The precision equipment must be far away from the devices with large vibration, such as washing and forging equipment.

3. Operators should have professional operation skills, including familiarity with the machines, understanding of precision machining, and familiarity with the characteristics of machining materials, etc.
