Two technical problems in flat key connections

1. Proposal of the problem In machines and tools, the shaft and the shaft (through the coupling) and the shaft to the hub are connected by a flat key. This is because the flat key coupling process is simple, the cost is low, and at the same time it can transmit a large torque, so people generally like to adopt it. In our mechanics business, we can almost solve the problem of processing flat keys and repairing keyways almost every day. This problem seems simple, but there are two problems that have given us

Gas Drilling

PDC cutters for oil&gas bits is produced by using the higher degree of diamond powder and tungsten carbide substrate. Microstructure with complete C-C bond combination is characterized between the diamond grains in polycrystalline diamond layer, which allows the high strength, hardness and wearing property of diamond layer. We adopt many types structure of the interface between diamond layer and carbide , and use the special technological post-processing in order to effectively reduce residual stress of PDC while make the interface combination firmer and more symmetrical. So Gas PDC cutter displays satisfying thermal stability, higher impact resistance and excellent performance.
