Industrial borescopes are widely and critically used in the field of mechanical manufacturing. Through non-destructive testing methods, they can penetrate deep into the interior of machinery, providing efficient and accurate support for quality control, equipment maintenance, fault diagnosis, and process improvement. Specific application scenarios and advantages are as follows:
Inspection of Holes, Grooves, and Threads: During the machining stage, industrial endoscopes can accurately detect the dimensional accuracy, surface roughness, and potential defects (such as cracks and burrs) of machined parts such as holes, grooves, and threads. For example, tiny cracks on the inner wall of an engine cylinder, if not detected in time, may lead to sudden equipment failure during operation. The high-resolution imaging technology of endoscopes can capture such defects, preventing quality risks.
Identification of Internal Defects in Castings: In the casting process, borescopescan penetrate into the internal cavities of castings to detect defects such as sand holes, pores, and shrinkage cavities. Through the digital image acquisition function of video borescopes, quantitative analysis of defects can be performed, providing a basis for casting grading and quality traceability.
Assembly Accuracy Verification: In the assembly of complex machinery such as engines and gearboxes, endoscopes can observe the assembly status of key components (such as pistons, connecting rods, and bearings) to ensure that assembly gaps and fitting accuracy meet design requirements. For example, in aircraft engine assembly, endoscopes can check the cleanliness of the combustion chamber and the installation position of turbine blades to prevent performance degradation or safety accidents caused by improper assembly.
Inspection of Concealed Areas: For concealed areas in mechanical structures such as deep holes, blind holes, and intersecting holes, the slender insertion tube and flexible steering function of the endoscope can achieve inspection without blind spots, avoiding quality risks caused by missed inspections.
Internal Wear Monitoring: Regularly using endoscopes to inspect the internal wear of equipment (such as gearboxes and hydraulic systems) can detect early failures such as tooth surface peeling and bearing raceway damage in advance, allowing for the development of maintenance plans and avoiding unplanned downtime. For example, in wind power gearbox maintenance, endoscopes can detect pitting and adhesion damage on the gear meshing surface and assess the remaining service life.
Corrosion and Carbon Deposit Cleaning: In the petrochemical and power industries, endoscopes can inspect the degree of corrosion and carbon deposits inside pipes and heat exchangers, guiding cleaning or anti-corrosion treatment to extend equipment service life. 4. Fault Diagnosis and Rapid Repair
Fault Location: When mechanical equipment experiences abnormal vibration, noise, or performance degradation, the endoscope can quickly locate the source of the fault. For example, in the fault diagnosis of CNC machine tool spindles, the endoscope can inspect the damage to internal bearings and seals, shortening repair time.
Repair Effect Verification: After equipment repair, the endoscope can verify the repair quality (such as whether cracks in the welded repair area have been completely eliminated), ensuring that the repair effect meets the standards.
Non-destructive Testing: Internal inspection can be completed without disassembling the equipment or damaging the structure, reducing inspection costs and avoiding secondary damage.
High Precision and Real-time Capability: Using high-definition imaging technology and real-time image transmission, it can capture micron-level defects and provide immediate feedback to operators.
Adaptability to Complex Environments: Flexible endoscopes can bend through narrow channels, while rigid endoscopes are suitable for straight cavities, meeting different inspection needs.
Intelligent Upgrade: Modern industrial endoscopes integrate AI intelligent recognition, 3D reconstruction, wireless transmission, and other functions, which can automatically analyze defect types, generate inspection reports, and support remote collaboration, improving inspection efficiency.
