How To Operate The Diamond Drill Bit Correctly

Diamond core drill bit is a drill bit used by drilling masters, for hard strata, sometimes really can only use diamond bit drilling. Do you understand the correct method of diamond bit operation? Here we diamond drill bit supplier will give you the right ways.

(1) Master the "five prohibitions": forbid drilling from the machine to add small drill pipe, forbid the use of good drill bit set sweep core, forbid the hole with foreign objects into the good drill bit drilling, forbid the pursuit of time efficiency spell bit to seize high production, forbid the pump water is not normal or the drill bit into the slow increase pressure forced drilling.

(2) Master the "three musts": the diamond core bit must be lifted upward when the drill is blocked and light rotation is ineffective, the core is blocked, and the drilling speed drops suddenly.

(3) When drilling under reduced pressure, use a wire rope to straighten the drill column and then reverse the rod. To prevent the drill bit from being damaged by sudden rotation under heavy load, lift the drilling tool away from the bottom of the hole with an oil cylinder before starting.

(4) To match the machine residual footage before drilling, and not to lift the drilling tool away from the bottom of the hole to lengthen the drill pipe during the drilling process in the return time.

(5) In complex strata, the drilling tool should not be lifted too fast and flushing fluid should be pumped into the hole at all times to prevent the hole from collapsing due to the "pumping" effect.

(6) The new drill bit must be "initially ground" after it has been put into the air. The purpose is: to understand the adaptability of the drill bit to the rock formation; to make the lip surface and the bottom of the hole to wear together; to erase the false size and angles of the drill bit.

(7) If the drill bit has the following conditions, it will no longer go down the hole:

        a,The table-set drill bit has a few diamond off-grain, squeeze crack or shear.

        b,The table-set drill bit has more than 1/3 of diamond particles exposed.

        c,Graphitization of the pregnant-set drill bit due to micro-burning.

        d,The drill bit has partial grinding or deformation.

        e,There are defects in the body.

        f,The size of the water outlet and water groove of the drill bit is too small.

        g,Severe erosion of the tire body.

        h,The drill bit has been abnormally worn.

        i,The cylinder body is deformed and the fillet is damaged.

With the rapid development of modern industrial technology, diamond has increasingly become an important industrial raw material, widely used in metallurgy, coal, petroleum, machinery, optical instruments, electronic industry and space technology departments.
