company news about To judge the quality of a processed part just look at these points and you'll be fine.

In the field of mechanical processing, the quality of the parts directly affects the performance and service life of the entire machine. To quickly determine whether a processed part is qualified, one actually only needs to focus on the following key points.

• First, check if the size accuracy meets the standards.** This is the fundamental criterion for evaluating the quality of a part. Whether the size is within the tolerance range directly determines the fit and operational stability during assembly. Especially for precision parts, even a very small deviation in size can lead to functional failure.

• Second, examine the surface quality.** High-quality machined parts should have a smooth surface without burrs, scratches, or machining residues. A good surface is not only aesthetically pleasing but also reduces friction and extends the lifespan. High-quality CNC machined parts usually have excellent surface roughness control.

• Thirdly, check if the materials are consistent.** The materials must comply with the requirements specified in the drawings or standards, and their hardness, toughness, corrosion resistance, and other indicators must not deviate. Qualified factories will provide material certificates or batch traceability information.

• Fourth, check whether the assembly and functional tests have been passed.** Even the most precise components are still of low quality if they cannot be properly assembled or do not operate stably. The actual assembly test is an important part of performance verification.

In addition, you can also check for quality inspection reports, whether it has undergone heat treatment or surface treatment, and the consistency control among batches. Truly good parts are not just judged by appearance; they also need to be tested in use. By mastering these points, you can quickly determine the actual quality level of a processed part.
