How to inspect precision machining parts?

Precision machine parts require precision. In the actual production process, we must reach the relevant standards for precision and try to improve it. At present, how to improve the precision of precision mechanical parts has become a key issue for related enterprises. The problems of deburring and polishing in the process of machining will directly affect the accuracy of parts, and it is also a difficult problem to solve in the current production automation. What I want to explain to you today is how to inspect precision machining parts?

One、 Basic requirements for inspectors:

1. To have professional knowledge and practical work experience, but also need to meet the requirements of the first product inspection work.

2. The measuring instruments used shall be verified by the measuring department and within the specified verification period.

3. Before product acceptance, it is necessary to be familiar with relevant drawings and technical documents, and understand the key dimensions of parts and key points of assembly.

4. The parts shall be determined in strict accordance with the requirements of drawings and technical documents.

5. Mark the products in process in the workshop according to the regulations.

Two、 Inspection system:

1. First inspection system: for the first part processed by each operator, it is necessary to conduct all-round inspection and keep it.

2. Inspection system: ensure that key parts will be able to obtain the whole process of controlled state.

3. Sequence transfer inspection system: for parts to be transferred to the next process, inspection shall be carried out to avoid unqualified products flowing into the next process.

4. Completion inspection system: the completion inspection shall be carried out for the products to be warehoused after the completion of production, including size and shape, whether there is missing processing procedure, etc.
