Do you know the testing methods for precision hardware processing?

Precision hardware processing is an important link in modern industry, where different materials are made into various precision hardware components, mainly used in fields such as automobiles, electronic products, healthcare, aviation, etc. Detection is one of the important links, which not only ensures production efficiency, but also ensures the quality and performance of the processed parts. This article will introduce the detection methods for precision hardware processing.

1、 Visual inspection

Appearance inspection is one of the most basic detection methods, which determines the quality of processed hardware components by checking their surface smoothness, shape, size, and so on. During the inspection, a magnifying glass should be used to carefully observe for any paint peeling, scratches, cracks, etc. In addition, thickness measurement, hardness measurement, metal composition measurement, and so on are also required.

2、 Dimensional inspection

Size detection is one of the most crucial steps in precision hardware processing, mainly checking whether the dimensions of the processed parts meet the specification requirements. The detection methods include coordinate measurement, universal tool tester, projector, and so on. Three coordinate measuring machine is a high-precision measurement instrument controlled by computers, which can achieve simultaneous measurement in three directions, providing a high-precision dimension detection method for precision machining of hardware components.

3、 Hardness testing

Hardness testing is an important testing method in precision hardware processing, suitable for measuring the hardness value of metal materials. At present, Vickers hardness, Brinell hardness hardness, Rockwell hardness and other methods are commonly used. Hardness value is one of the indicators reflecting the properties of metals, and different materials have different hardness values. Hardness testing can be used to determine the properties of materials such as strength, hardness, and toughness.

4、 Metal composition detection

Metal composition detection mainly measures and analyzes the metal elements composed in metal materials to determine whether the metal components used meet the requirements and objectives. At present, the commonly used metal composition detection technologies include static phase analysis, spectral analysis, chemical analysis and other methods. These methods can determine the composition of various metal alloys and determine whether they are qualified.

5、 Surface cleanliness testing

The surface cleanliness in hardware processing not only affects product quality, but also affects equipment production efficiency. Therefore, surface cleanliness testing is also one of the important testing steps. The commonly used surface cleanliness detection methods include adhesion method, smoothness detection method, and visible spectrum method. Smoothness detection is mainly to use a spectrometer to sweep a simple radiation light across the sample surface. The spectrometer can detect organic and inorganic substances on the material surface, measure their light reflectance, and then determine the surface cleanliness.

In summary, the detection methods in precision hardware parts processing are diverse, including appearance inspection, size inspection, hardness inspection, metal composition inspection, surface cleanliness inspection, and so on. These testing methods can ensure product quality and meet customer expectations. Through scientific and reliable methods, more product information can be obtained to understand product defects and quality issues. When conducting testing, different testing methods should be selected appropriately based on different testing purposes and requirements to ensure the quality and performance of hardware processing.
