Abstract: Brazed diamond abrasive drill was suitable for drilling holes in carbon fiber reinforced silicon carbide ceramic matrix composites, but a large amount of chips could adversely affect the drilling process of the holes. Therefore, according to the chip discharge process, the chip morphology was analyz...
Abstract: The grinding power monitoring experimental platform was built with PPC−3 power sensor and NI 9203 acquisition card. An intelligent grinding process decision-making system driven by monitored power data was developed based on LabVIEW software to promote green, efficient and intelligent grinding. In o...
Abstract: In order to solve the difficult problem of dressing micro-grooves on the surface of metal-bonded diamond wheel, an infrared nanosecond laser was used to carry out the dressing test. The influences of laser average power, pulse repetition frequency, laser ablation time and other factors on the materi...
Abstract: The oxidation reaction mechanism of diamond grits in diamond/borosilicate glass composites was studied. The composites were sintered at different conditions and the samples were analyzed through TG–DSC, XRD and Raman. The results showed no chemical reaction occurred when borosilicate glass was sinte...
Abstract: The application of the cast WC, the Co powder coated cast WC and the Ni powder coated cast WC particles in diamond saw blades were studied, and their effects on the mechanical properties, the micro morphologies and the cutting properties of the diamond saw blade matrix were explored. The results sho...
