本文就金刚石薄壁钻头钻进钢筋混凝土的特性 ,按不同的胎体材料与固结在胎体材料中的金刚石设计钻头。通过大量的试验 ,提出以所钻切的钢筋大小和含量 ,即以钻切的钢筋面积来具体评价金刚石薄壁钻头的性能 ,同时结合理论加以分析。GD2 配方作为最佳的胎体材料 ,选用高品级的金刚石 ,适当的浓度和粒度与之相匹配可在生产使用中获得良好的经济效益
In this paper, diamond thin-walled drill bit into the characteristics of reinforced concrete, according to different carcass materials and diamond-shaped drill bit in the carcass material. Through a large number of tests, it is proposed to evaluate the performance of the diamond thin-wall drill bit by the size and content of the steel bar to be drilled, that is, the area of the rebar to be drilled and cut. At the same time, the theory is analyzed. GD2 formula as the best carcass material, the selection of high-grade diamond, the appropriate concentration and particle size can be matched in the production and use to obtain good economic benefits
