Shenzhen precision parts
processing to determine the importance of proper inspection methods commonly used mechanical processing plant of the three dimensional precision testing equipment, two yuan, height gauge, etc.
In precision parts processing, inspection, general inspection methods are: direct test, the indirect test, exposure method and does not contact method, etc.
In actual inspection of these methods have certain relativity, therefore in the process of actual operation, precision parts inspection shall be based on actual situation as the basis, based on the scientific comparison and analysis of different test methods, to determine an appropriate test method.
First of all, for precision machinery parts processing design drawings required by the relevant content, inspection shall be conducted, and the parts with the quality standard authentication;
Secondly, for the parts processing quality in the process of observation, through to see if there are any more bad judgment problem, and the inspection shall be practiced for parts and surface appearance, to confirm whether consistent with design requirements and expected standards;
Third, choose the reasonable detection tools and precision parts machining
accuracy for measurement;
Fourth, to check whether there is error precision location precision parts, and record test data and the related content, in order to prevent the missing problem in the overall inspection.
In terms of mechanical parts processing quality inspection, reasonable selection testing tool is a top priority, when the choice should be the actual detection based on: 1.
Parts to make use of height gauge and optical instrument measurement process, the measuring range has a certain standard limit, in a size in this range, on the basis of to use the measuring tool for testing;
Ring gauge and other tools in the test precision parts with fixed quantity;
In the process of mechanical parts processing quality inspection, due to its environment and the measurement location is not fixed, when choosing measuring tool also should be based on the specific measurement environment, choose tools for measuring with pertinence, and need to know and research parts design drawings, on this basis to ensure that the selected measuring tool more reasonable, can make it has practical application value, ensure better play a role in the process of actual inspection.
