    Precautions for receiving and quality inspection of precision hardware parts

    The receiving quality inspection of precision hardware parts is an important link to ensure product quality and performance. The following are the precautions to be taken when conducting quality inspection of precision hardware parts upon receipt:1、 Appearance inspectionCheck surface defects: Observe whether there are defects such as rust, cracks, deformation, burrs, folds, slag inclusions, pores, etc. on the surface of the parts. These defects may affect the performance and safety of the parts.Color and glossiness: Check whether the color and glossiness of the parts meet the requirements, which helps to preliminarily determine whether the surface treatment process of the parts is qualified.Identification and packaging: Ensure that the packaging of the parts is intact, free from damage or stains. At the same time, verify the identification information on the parts, such as brand, model, production date, etc., to ensure con

    CNC hardware processing product quality inspection process and precautions

    The quality inspection process and precautions for CNC hardware processing products are crucial to ensuring product quality. The following is a detailed explanation of the quality inspection process and precautions:1、 Quality Inspection Process for CNC Hardware Processing ProductsPreparation before processing:The processor needs to carefully review the content of the process card, clarify the part, shape, and drawing dimensions of the workpiece to be processed.Measure the size of the billet to ensure compliance with the drawing requirements.When clamping the workpiece, check if its placement is consistent with the programming operation manual.Rough machining self inspection:After rough machining is completed, perform self inspection immediately to check whether the workpiece is loose and correctly centered.Measure the dimensions from the machining area to the reference edge (reference point) to ensure compliance with the d
