Analysis of Brightstar's daily work in parts inspection

The quality of machined parts is the foundation for ensuring product performance and reliability, and the machined parts inspectors are the key guardians of this quality checkpoint. Their daily work seems ordinary, but in fact they shoulder great responsibilities and cannot tolerate any carelessness.

After arriving at work every day, the inspector's first task is to check the inspection equipment and tools. Precision measuring tools such as calipers and micrometers need to be carefully calibrated, and equipment such as hardness testers and polymer detectors need to be preheated and functionally tested to ensure measurement accuracy and normal operation of equipment, laying a solid foundation for inspection work.

After preparation, the inspection process is officially started. According to the production plan and drawing requirements, the parts to be inspected are collected, and the first step is to conduct an appearance inspection. With experience and keen observation, the inspector carefully checks whether there are defects such as cracks, sand holes, pores, scratches, etc. on the surface of the parts. Once unqualified parts are found, they are immediately marked and isolated to prevent mixing with qualified products.

After the appearance inspection is qualified, the core link of dimensional accuracy inspection is entered. The inspector strictly compares the dimensional tolerance of the drawing and selects appropriate tools for precise measurement. For shaft parts, measure diameter, length, and cylindricity; for hole parts, test hole diameter, hole depth, coaxiality, etc. During measurement, carefully record each data to ensure authenticity and traceability. For dimensions at the critical value of tolerance, measure multiple times to ensure accurate judgment.

The geometric tolerance and surface quality of parts are equally important. Use height gauges and dial indicators to detect geometric tolerances such as flatness, verticality, and parallelism, and use roughness meters to measure surface roughness. For key functional parts such as mating surfaces and sealing surfaces, any slight deviation may affect assembly and function, and must be strictly controlled.

Sudden problems often occur during the inspection process. If batch quality problems are found, the inspector will report them immediately and assist the production department in analyzing the causes and making improvement suggestions. At the same time, full inspection or random inspection of the produced parts is carried out to prevent unqualified products from flowing into the next process, and the parts after rework and repair also need to be re-inspected.

At the end of the daily inspection, the inspector will organize and analyze the data. Count the types and quantities of defective products, draw quality control charts, find quality fluctuation patterns and potential problems, and submit reports to the quality and production departments regularly to provide data support for optimizing production and improving quality.

In addition, our inspectors continue to learn new inspection standards, process knowledge and testing technologies, actively participate in quality improvement activities, share experiences, and continuously improve their professional capabilities.

Although the daily work of machined parts inspection is tedious and the responsibility is heavy, it is a key link to ensure product quality. At Brightstar, every inspector is guarding the lifeline of product quality with a rigorous attitude and professional skills, and contributing to providing high-quality parts to global customers.
