Research on Spiral Drill Stabilizer Wear-resisting Layer Repair Technology

摘要

This paper introduced the repair methods of wearresistant layer of the drilling tool stabilizer, and proposed a simple fitting method for spiral drill stabilizer wear belt, fitting of spatial spiral surface is essence of the space spiral curve fitting, for a pitch fixed spiral can be expanded to twodimensional line, and then using interpolation technique can control drill stabilizer and repair work head of joint motion, the synthesis of these two motions is the space spiral.
