点胶法可实现金刚石有序排布进而提高钻头性能
Diamond grits are ordely arranged through dispensing method thus improving bit performance
摘要
Abstract
To orderly arrange diamond grits in impregnated diamond bits, dispensing is applied in preliminary experiments on arranging diamond grits.Matlab2016A image analysis tech provides a quantitative evaluation scheme of grit positioning accuracy.Then a single layer electroplated diamond bit with orderly arranged grits is prepared to compare its performance with that of common bits in actual drilling.Results show that dispensing helps to orderly arrange diamond grits, whose deviation ratio over the design scheme is less than 10%, and that grit-arranged bit performs 30% increase in efficience and 85% in bit life than common bits.In conclusion, dispensing method is reliable to orderly arrange diamond grits in a bit, who has significant advantage over common bits.关键词
