The toughness of the blast furnace bit can break rock and rock, and it is an indispensable mechanical supply in the mining industry. Such as drilling, mining, etc. - such drill bits can be used everywhere, as well as blast furnace openers. Then the drill bit will always be worn during use, and it needs to be ground to continue; to use, first place the main cutting edge of the drill bit and the grinding wheel surface on a horizontal plane, that is, after the position is set, slowly move to the grinding wheel surface Rely on. ⒉The angle at which the axis of the drill bit is inclined to the surface of the grinding wheel. This angle is the sharp angle of the drill bit. If the angle is wrong at this time, it will directly affect the size of the top angle of the drill bit, the shape of the main cutting edge and the bevel angle of the chisel edge. This refers to the positional relationship between the drill bit axis and the surface of the grinding wheel, just take it, this angle can be seen more accurately. Here we should pay attention to the drill before sharpening. The relative horizontal position and angular position should be taken into consideration as a whole. Do not ignore the angle of the angle in order to level the edge, or ignore the level of the edge for the sake of setting the angle. The blast furnace bit is an indispensable accessory in the drill pipe. It is used to drill through holes or blind holes in solid materials, and can expand the existing holes.

You can purchase blast furnace drill bits that are suitable for you according to your own production environment. . How does a blast furnace drill work? During digging, the drill bit rotates around the vertical axis and moves axially at the same time. The soil is cut under the action of the torque and axial force of the drill bit, and is pounded and broken under the action of the extrusion and centrifugal force of the working blade, forming a soil flow that is pressed to the pit wall, and at the same time is lifted to the surface along the page. When the soil flow moves to the place without the obstruction of the pit wall|, the broken soil is thrown around the pit due to the centrifugal force, and the whole process of digging the pit is completed. Therefore, although the work of the blast furnace drill is boring and tasteless, it is important to our life. The front and back of the twist drill in the furnace dismantling machine are curved surfaces. The front and back angles of each point along the main cutting edge are different, and the strength is low. The sharp cutting speed is large, so the wear is serious. Therefore, the machined hole accuracy is low. The main cutting edge of the drill bit of the furnace demolition machine participates in cutting, and the cutting speed and speed of each point on the edge are not equal, which is easy to form spiral chips, and chip removal is difficult. Therefore, the chips are squeezed and rubbed against the hole wall, often scratching the hole-wall, and the surface roughness after processing is very low. The diameter of the twist drill is affected by the hole diameter, the spiral groove makes the drill core thin, and the drill bit has low rigidity; there are two rib guides, the axial resistance becomes larger, and the drill bit is easy to swing. The shape and position error of the drilled hole is large. After use, disassemble it, lift the drill pipe (with drill bit), connect the drill box body of the furnace dismantling machine to the turntable as required, lift the drill pipe so that the groove of the drill bit corresponds to the convex point of the core board of the drill bit box, and the drill bit is stuck in the In the drill bit box, withdraw the drill rod and drill bit in turn. There are many types of blast furnace drill bits, commonly used in mines, type, type, type, larger, useful, and so on for drilling teams. You can buy blast furnace bits suitable for your own production environment. How does a blast furnace drill work? During the digging operation, the drill bit revolves around, the shaft rotates, and moves axially at the same time. The soil is cut under the action of the torque and axial force of the drill bit, and is smashed and smashed under the action of the extrusion and centrifugal force of the working blade. For a long time, all kinds of blast furnace drill bits, blast furnace drill bits wholesale-, blast furnace opening drill bits, and opening machines are sold to the whole country at high prices for a long time. The drill bit and blast furnace drill manufacturer are reasonable: reasonable price and perfect service, which have been recognized by the majority of customers. The soil flow is formed to press against the pit wall, and at the same time, it is lifted to the surface along the page. When the soil flow moves to the place where there is no obstruction by the pit wall, the crushed soil is thrown around the pit due to centrifugal force to complete the entire digging process. Therefore, the main models of blast furnace opening heads with complete models but important to our life are φ～φ blast furnace high temperature resistant drill bits and φ～φ mine drilling bits. Although the work of the blast furnace opening head blast furnace drill bit produced by us is dull and boring, the diameters range from mm, mm, mm, mm, mm, mm, mm to mm, mm, mm, mm, mm, etc., and can also be customized according to drawings and samples. , fully meet the needs of different customers.
