摘要
Abstract
Utilizing domestic hinge-type cubic press , the un-planar surfaces polycrystalline diamond compacts used in oil drilling were synthesized under high temperature , high pressure and subsequent processing conditions , including 3-ridge , 4-ridge and 5-ridge cutters . Meanwhile , the influences of cutting edge and vertical direction angle on the performances of 3-ridge , 4-ridge and 5-ridge cutters were investigated . The laboratory testing results show that the wear resistance , loading force and fatigue resistance of the 3-ridge , 4-ridge and 5-ridge cutters ( the angle between the cutting edge and vertical direction is 90°) are the same as that of the ridge-cutter;compared with flat cutters , their wear resistance and fatigue resistance are increased by about 58 .6% and 51 .8% respectively , and the loading force is reduced by 41 .9% . When the 3-ridge , 4-ridge and 5-ridge cutters′angles between the cutting edge and vertical direction are 99° , the average values of their fatigue resistances are about 30% higher than that of 90° under the same conditions of wear resistance and grinding loading force , and about 95 .7% higher than that of the flat cutters .关键词
