Experimental Research on Superlong Deep-Hole Drilling Processing Technology for Steel of 4145H Drill Collar
Through the analysis for steel of 4145H drill collar, Research into the various factors of cutting, such as the cutting tool material, cutting-tool angle and cutting parameters, combined with the actual structure of the workpiece and the superlong deep-hole processing method for study. In the test, the machining process is analyzed, especially the process of boring and honing. The test result indicates that the trepanning process is stable and reliable to solve the superlong deep hole (Φ71mm×7500mm) of 4145H drill collar steel processing problems of production if the optimizing cutting method is appropriate and the cutting tools and the cutting parameters are rational.
