The invention provides a turning method of an annular deep narrow groove of a high-temperature alloy integral impeller. The turning method aims at reducing the cutter breakage when the annular deep narrow groove of the high-temperature alloy integral impeller is turned, reducing the production cost and achieving the part machining in a high-quality and efficient mode. The narrow groove of the integral impeller is poor in openness and large in machining difficulty and accordingly a machining area of the annular deep narrow groove is divided into three areas, a feasibility machining route is determined, part of the narrow groove is turned, the position of a wheel disk is machined, the narrow slot allowance is removed fully, and accordingly the optimal machining quality of the integral impeller is ensured. According to the turning method of the annular deep narrow groove of the high-temperature alloy integral impeller, the annular deep narrow groove of the high-temperature alloy integral impeller is turned through variable parameters and accordingly cutting parameters are optimized, the cutting vibration is reduced, and accordingly the durability of a cutter is improved, the cutter breakage is reduced, and the high-quality, efficient and low-cost machining on the annular deep narrow groove of the high-temperature alloy integral impeller is implemented.
