deep hole threaded drill manufacturers support customization [Tungsten Carbide Inserts]
It is a company that produces drilling tools in the drilling tool industry and has domestic advanced production and inspection equipment..The business scope includes rock drilling tools, drill rods, drill bits, light drilling tools, heavy drilling tools, down-the-hole drilling tools, coal machinery and milling gears, etc., covering all fields of rock drilling system.Production and sales of other related machinery and equipment, etc..
Taper connection column tooth bit, taper connection column tooth bit is mainly used with pneumatic rock drill and taper rod. The drill bit is connected with the drill rod for drilling operations. It is mainly used for secondary crushing in mines and anchor rods. Support, tunneling and other fields.During drilling, the phenomenon that the drilling tool is stuck in the well and cannot move freely due to various reasons is called stuck. It mainly includes keyway stuck, sand stuck, well collapse stuck, differential pressure stuck, and reduced diameter stuck. , Falling object stuck drill, sand bridge stuck drill, mud pack stuck drill and drill tool fall off, stuck drill, etc..Formation structure, poor drilling fluid performance, improper operation, etc. may cause sticking.Must be analyzed for specific situations.In order to effectively remove the card.Keyway jams mostly occur in hard formations, with large changes in well deviation or azimuth.Where formed, when drilling, the drill string section rotates.
(1) When drilling rock, before the first opening of the eye is 2 to 5 cm deep.It is not advisable to use full wind. After 5 cm of drilling, full wind can be used, so that the rock will be smooth and the drill bit will not be bounced..It is not easy to damage the drill bit, otherwise, it is very easy to cause the cutting edge of'T to break, and the drill rod is very powerful..Laborious operation.It is also small to be able to drill smoothly, but it affects the drilling speed,
(2) in the broken rock.If there is a sticking phenomenon, you should look for the cause in time, whether the size of the drill bit is appropriate, whether there is any broken stone, etc., the width of the worn end face of the drill bit should not exceed 2 to 3 mm. Under normal circumstances, the inline drill bit should be scrapped with a sword. It can be polished 10-15 times, when the alloy sheet at both ends of the drill bit is left 3-5mm.It can be considered that the drill bit has reached the level of scrap, the type and reason of the damage of the deep-hole rock drilling cemented carbide bit. The main damage of the deep-hole rock drilling cemented carbide bit is the fracture of the bit body and the damage of the cemented carbide sheet..
What is a column tooth bit
Column tooth bit, also known as column tooth air drill bit, column tooth bit; it is a drill bit product produced by the multi-meter down-the-hole drill bit.
Since its establishment in 2009, the multi-meter down-the-hole drill bit has been focusing on customer needs, bringing together domestic drilling tool development experts and engineering and technical personnel, and at the same time cooperating with relevant domestic scientific research institutions to continuously strengthen investment in product innovation. Customers have different requirements for products, and they have domestically imported machining centers and heat treatment equipment as well as complete inspection systems.
The column tooth bit has 32, 40, 42 and other product models, and it has the characteristics of no grinding and fast drilling speed. The column tooth bit is made of YG13 alloy and 40 chrome steel body through welding, which has obvious advantages such as saving time and labor. , The connection method is simpler, more durable and has a longer service life, etc..
The column tooth drill is made by advanced processes such as circular hacksaw forging, hot forging, drilling and milling machine processing, etc..
What are the uses of column tooth bits
Column tooth bit and b22 drill pipe can be used together. The bit product is widely used in coal mine, iron ore, gold mine, copper mine, lead-zinc mine and other rock drilling projects, mining, railways, tunnels, and highways. And other engineering construction.
The multi-meter down-the-hole drill bit also focuses on the supply of accessories such as "drill bits", "coal drill bits", "drill pipes", "B19 drill pipes", "rock drill bits" and "impacters".
Column tooth bit is a new type of drill bit in which the cemented carbide is columnar and is embedded in the bit body in a point shape..
Advantages of column tooth bit
The blast hole is easy to open the door, not easy to stick, the blast hole is rounder, the drilling speed is higher, and the amount of coarse-grained cuttings, the broken specific work is low, the dust concentration on the working face is low, and the consumption of cemented carbide is also less. Grinding costs are also low, but the diameter of the borehole should not be less than 40mm.
Column tooth bits are being used more and more on-site due to their unique advantages.
In the standard, the matching tolerances of the diameter of the shank and the shank are stipulated.There are three types of shank (flange) shank, shank (lug) shank and spline shank, and shoulder shank for light pneumatic rock drills.The shank of the heavy rail type rock drill is always installed in the shank sleeve.Can be regarded as a part of a rock drill.Shank shank or spline shank.In the case of the same clearance between the shank and the shank, the longer the length of the shank, the less likely to be deflected when impacting the shank, thereby reducing the rock drilling speed, reducing the wear with the shank, and reducing the wear of the shank at the same time. life.If the length of the shank is too long, it will increase the weight of the drill rod itself and the rock drill. The shank must have a moderate length. At present, there are three types of shank lengths in the world for pneumatic rock drills, 108mm and 159mm..Which only applies to small rock drills.
Brazing rod and the entire rock drill bits) is a new way for humans to conquer rock and ore.It consists of a slender rod system, in dth drill pipe Under severe abrasion of rocks and ore, high pressure flow (or pressure) and erosion and erosion of mine water, it is pulled every minute..The load capacity of pressing, bending, twisting and rock drill is about 2000 to 9000 times. For high frequency impact.The impact energy is as high as 25-500J, which tends to cause stress corrosion fatigue fracture, and the service life is only tens of minutes to tens of hours. Rock drill bits are demanding in the basic industry of human machine tools, with short life, high technical content and large consumption. A kind of tool, excavator workers in more than 100 regions and regions in the world work 8 hours a day.More than half of them dig holes in rocks and ore, and the annual consumption of drilling tools required is about 50 times that of the domestic market..
