Engineering ceramics are increasingly extensively applied in the aerospace, vehicle, armor protection and other fields due to their excellent performances such as high compression strength, hardness, low density performance. However, engineering typical difficult-to-machine materials, especially hole machining under constant feed rate, which limits promotion application. In this study, by combining a specially developed novel thin-wall diamond trepanning bit with low-frequency axial...
Non-destructive testing (NDT) of rock bolt anchoring quality is an important part engineering and safety control, electromagnetic ultrasonic NDT one the promising detection methods, it key to obtain effective information by optimizing bias magnetic field improve efficiency transducer. In this paper, several factors affecting are studied, work divided into simulation demonstration: using COMSOL simulate transducer(EMAT) analyze influence number circuits, magnet thickness, yoke thickness on...
Radon, which comes from the radioactive decay of uranium or thorium in rock and soil, easily accumulates is difficult to discharge underground spaces, its concentration often higher than that indoors on surface, posing a major threat health people living working therein, continuous monitoring radon air spaces necessary. At present, although there are commercial detectors, most them either not able monitor online for long time, expensive, equipment large complex, suitable humid conditions...
Bulletproof ceramics are usually hard and brittle with high elastic modulus, compressive strength, low tensile strength. While machining bulletproof ceramics, severe tool wear makes it difficult to obtain desired quality efficiency, especially in hole drilling. In this work, an intensive experimental study on the overall rate of sintering diamond thin‐wall core bit during drilling Al 2 O 3 (99 wt.%) has been carried out. The loss after each drilled was selected for representing bit. Based...
Glass Fiber Reinforced Plastic is widely used in manufacturing and other fields because of its high specific strength modulus. Since the workpiece requires secondary hole processing during assembly, machining defects are prone to occur making, which seriously affects service life workpiece. A novel type thin-walled diamond trepanning bit was fabricated combined with ultrasonic technology conduct a pilot study on processing. Compared conventional twist drill processing, grinding hole-making...
