In the formula: σd one-one diamond compressive strength, MPa; σA uniaxial compressive strength of a rock, MPa. Under the premise of guaranteeing the quality of diamonds, impregnated bits should be used in hard and hard rock formations with a smaller grain size to facilitate the wear of the carcass and the inability to work. As the stone continues to fall off during the drilling process, the new diamond is continuously put into work to realize the self-sharpness of the diamond drill. However, in soft to medium-hard rock formations, the coarser diamonds should be used to ensure that the end face of the drill head has a larger mountain edge and cutting depth to maintain a higher drilling rate. The selection criteria for diamond grade and grain size are: the rock is hard, diamonds with finer grain size and higher grade are used; if the rock is soft, coarse gold is used. Gangshi. See Tables 5 - 20 and Figures 5 - 30 0 Practices   It is proved that the use of mixed-grained diamond in the drill bit is more conducive to expanding the adaptability of the drill bit to the rock formation and improving the drilling speed.    Rock properties Medium hard abrasive rock formations (Class 7 8) Hard-hard, fissured or broken strong abrasive formation (9 12) Hard-hard abrasive rock formation (Level 9 12) Diamond particle size (heading> 45/50-50/60 50/60 one coin /70 70/80 Diamond Grade MBD6 (JR4) MDB8 (JF) MBD12     Fifth, diamond concentration and diamond distribution on the lip surface     Diamond concentration The diamond concentration of impregnated diamond drill bits is expressed in terms of volume concentration, ie: V_ K =x 100% Where: v1—the volume of diamond in the carcass, cm3; V one carcass volume, cm3 o      ( 5 -25 )    When K = 25 %, the concentration of plutonium and carnivorous industry is said to be 100%. At this time, the weight of diamond contained in each lcm3 carcass is: g = 1 × 0. 25p = 1 × 0. 25 × 3. 52 = 0. 88g = 4. 4cC of which diamond density ρ = 3. 52g/cn13. The diamond content in unit carcass volume for different concentrations is shown in Table 5-21.  Table 5 - 21 Diamond content in units of different carcass volume  The Diamond concentration (%> (International wheel industry concentration)   Coix Low concentration Medium concentration High concentration Belgium 75o/o 90% 110% United States, Canada 50% 80o/o 1 meter)% Czech Republic 60% 759 Gross 90% Fluctuation Range 50% 759 Gross 759 Gross 90% 90% 110%   Dry Diamond Polishing Pad The selection principle of diamond concentration is: the diamond concentration must ensure that the amount of diamond on the working lip of the drill bit is sufficient The cutting ability, and must make the bit has a higher wear resistance. If the concentration is too low, the lj cutting ability is low: if the concentration is too high, it will affect the ability of the carcass to insert diamond, but it will reduce the wear resistance. Generally, the diamond concentration must not exceed 125%. The diamond concentration must be reasonably select.ed according to the nature of the rock, as follows: 1 Drillability back ] Grade X medium hard and medium hard abrasive rock: diamond concentration 75% 90%; 2 Drillability should be XII hard-firm abrasive rock: diamond concentration 50% 75%; 3 Drillability JX-XII grade hard and strong abrasive rock: diamond concentration 100% 1lO o/o. 2. The distribution of diamond on the lip surface The diamond concentration is proportional to the number of diamonds on the unit lip and the number of diamonds on the unit cutting line. Former Soviet Union A  Fig. 5-31 Cumulative wear of drill lip and three different positions in relation to drilling footage 1. Inner Ring; 2. Outer Ring; 3. Central  From Fig. 5-32, it can be seen that the bit wear has three different stages. In the first stage, the footage is about 5m. The wear of the three different parts tends to be consistent: in the second phase, the wear inside and outside is significantly increased; in the third phase, the wear of the inner and outer rings slowly increases, so the drill bit must be protected.
