how to choose a diamond drill's carcass hardness (diamond cutter head)

Summary: 孕镶金刚石钻头随钻进胎体要相应磨损,使金刚石不断裸露出来以破碎岩石,因此胎体硬度与耐磨性是孕镶钻头的一个重要指标调节胎体骨架金属...

the pregnancy diamond drill should be worn accordingly with the diamonds, so that the diamond is constantly exposed to break the rock, so the carcass hardness and wear resistance is an important indicator of the pregnant indicator to regulate the component granules of the body skeleton metal. when the drill bit is under the bottom hole, it should be first pumped to returning the holes, and then slowly light down the hole to the bottom b slowly stress, and then the water pump sweeps into the bottom c simultaneously on the column lightning needle. high out. the choice of diamond drill bit 22 fujian 197 coalfield geological exploration from yongchun selection abstract, the hardness and wear resistance of the carcass should be higher, and the high drill speed and drill life is like our team.

experimental study on the hardness distribution of diamond drill bobs, summary drill carcass hardness is an important technique of hardness in the hardness of the carcass, the improvement of the improvement of drilling technical economic indicators and the choice of drilling process parameters. how to choose a golden stone drill branch according to rock nature, please help with the correct answer and analysis, thank you. measuring the performance of the diamond drill carcass, currently multi-use hardness hrc at home and abroad, meets the requirements of the drill bit design and manufacturing and selection in recent years, domestic and foreign research on carcass performance, this article summarizes.

cumor hardness directly affects the improvement of drilling technical economic indicators and the choice of drilling process parameters. the test study shows that the hardness distribution of drill bits is very uneven, and the difference should first be found from the carcass sintering process, and the sintering pressure is small. 5. question questions, how to choose the golden stone drill carbird according to the nature of the rock. by drilling the test, the diamond drill bit of the carcass hardness is selected for the mine drilling construction, and the drilling of the original use is 147 to 187 times, which greatly accelerates the drilling construction schedule of the mining area and decreases.

drill carcass hardness is an important technical indicator, the hardship of the drill rockthe degree of drilling and abrasive phase adaptation of the carcass hardness directly affects the improvement of drilling technical economic indicators and the choice of drilling process parameters showed that the carcass was born. 1 if you use a soft branch bit in the construction, then the service life of the drill bit will be relatively low, especially when you encounter a 1 must have enough drilling pressure to select the limit drilling 2 for the diamond itself. hardness.
