Safety in Tungsten Carbide Dental Burs Use

Eye protection must be worn to protect against ejected particles.

Surgical mask must be worn to avoid inhalation of aerosol or dust generated.

Inspect the bur for broken flutes before each use and discard defective burs.

Ensure that the bur is fully seated and gripped in the handpiece collet.

Maintain handpieces in good working order and correctly lubricated.

Do not exceed the maximum speeds tabulated above.

Move the bur continuously when in use to avoid localized heating.

Clean and sterilize the burs in accordance with the directions below before first use an before each reuse.

Tungsten Carbide Valve Ball

Tungsten Carbide Valve Ball Picture

Tungsten carbide valve ball is an important part of globe valve , globe valve can make use of the handle or other drive means rotating sphere 90. So that the hole of the ball and the valve overlap or vertical centerline of the channel, to achieve the valve fully open or fully closed action, usually working in harsh environments. tungsten carbide valve ball with high hardness, wear resistance, corrosion resistance and high temperature, etc., and therefore mainly used in all kinds of sealing work, such as: pump, thermal power plant ash slagging water systems, fluid seal rotating ball.

Valve ball, the role of a one-way valve to control the flow of oil flow, is in a very poor conditions of work. Multi-component working medium is air, water, oil, sand, wax, resin and asphalt, is a random change and non-uniform three-phase medium. Pumping liquid carry some mechanical impurities at high speed flows violently scour the ball, the ball and seat, has produced hit between the hood, a large quantity of oil wells in the sand, make the ball and seat sealing surface between the damage more rapidly, this damage is a mechanical wear. In most wells all contain corrosive medium, which valve bal is particularly serious corrosion damage. Crude oil contains H2S, Cl- ,salt, alkali and other,so chemical or electrochemical reactions can occur with metal, the metal from corrosion. In the dual role of mechanical abrasion and chemical corrosion, precision ball and seat drop, sealing destroyed, its performance for many irregular surface pitting, flaking, mesh ditch, thereby enabling the valve is fully failure, significantly decreased pump efficiency. Make tungsten carbide as the main material can better adapt to pump operating conditions. Obviously, for the harsh conditions pump, manufactured with tungsten carbide valve ball valve is an ideal material. In short, tungsten carbide valve ball used in pump, both in diluted oil, or heavy oil, high sand, wax wells, or wells rich in corrosive media,will produce good results, and will have a broad application prospect.

Tungsten carbide valve ball cost is higher, but due to the life of tungsten carbide valve ball higher than steel valve ball several times, can better adapt to the harsh working conditions in the underground, and would reduce leakage and improve pump efficiency and prolong pump inspection cycle , thus the increase in crude oil prices, operating costs savings far ccover the cost of increasing the number of tungsten carbide valve ball . Thus, making use of tungsten carbide valve ball has a very substantial economic benefits.

Tungsten Carbide Button

Tungsten carbide button is widely used as the most popular mining bits tool in modern industries, therefore, they are also named tungsten carbide mining bits, tungsten carbide button bits or just tungsten carbide mining buttons, etc. And as their material is cemented carbide, so cemented carbide buttons are also widely used among the users.

Tungsten Carbide Button Picture

Our advantage of making tungsten carbide button bits is that we are using HIP sintering for minimizing the porosity of carbide blank for increasing the transverse ruputure strenth (TRS). It is very suitable for high quality requirment for making carbide bottons to be ued in high and medium pressure DTH Drilling. As its unique working performance, tungsten carbide button bits are widely applied to oil filed drilling and snow removal, snow plough machines or equipments.

Tungsten carbide button as its unique performance are widely application for oil filed drilling. tungsten carbide buttonAccording to the different oil-field drilling machinery such as Roller Cone Bits, DTH Bits, Geotechnical Drilling Tools, Drifter Bits, button been divided into different standard styles : P type flat-top bits, Z type coin spherical bits, X type wedge bits. Quality are guaranteed by our steady and higher technic.

1.Tungsten carbide button is used in the coal cutter drilling tools, mine machinery tools and road maintenance tools.

2.Tungsten carbide button are widely applied for rock tools, mining tools for use in quarrying, mining, tunneling, and civil constructions.

We offer Tungsten Carbide Buttons. All of our tungsten carbide products are made with Virgin Raw Materials and processed in HIP/Sintering unit, be of very high quality and excellent performances.

Tungsten Carbide Tips

Tungsten carbide tips are made from tungsten carbide powde and cobalt or other binders, which owns the properties of high hardness, wear and abrasion resistance, cemented carbide is the ideal material for many cutting tools and mechanical parts.

Tungsten Carbide Tips Picture

Tungsten carbide tips as the common part of tungsten carbide tips, one tungsten carbide tip can replace 4 to 10 steel tips, its penetration rate twice as high, while the tungsten carbide drill tip replacement less often, improve production efficiency, perforation rate. Tooth tungsten carbide drill for, it is required to adapt to a variety of rock properties teeth, perforation rate, abrasion resistance, shock resistance, so as to achieve long service life. Tungsten carbide drill tip has become a major tool for high-efficiency perforated. Currently tungsten carbide tips for large and medium-sized open-air metal mines, especially for large open pit type non-ferrous metal perforation, tungsten carbide tips has broad prospects.

Tungsten carbide tips take on the important task of engineering geology, oil exploration, mining and civil construction. Tungsten carbide tips as traditional tips, tips by the complex role of impact and abrasion, harsh working conditions, there are at least wear mine rock form more than four, namely: thermal fatigue wear, shock wear the shock of fatigue wear and abrasive wear. tungsten carbide tips compared with the general tips, have higher hardness, strength and toughness. tungsten carbide able to adapt to changing conditions better,and under the guarantee toughness does not fall have further improve the wear resistance of the alloy.

What is Tungsten Carbide Indexable Inserts

Tungsten carbide inserts are replaceable and usually indexable bits of cemented carbide used in machining steels, cast iron, high temperature alloys, and nonferrous materials. Tungsten carbide indexable inserts allow faster machining and leave better finishes on metal parts. Tungsten carbide indexable inserts can withstand higher temperatures than high speed steel tools.

Tungsten Carbide Indexable Inserts Picture

Tungsten carbide indexable inserts are composed of a metal matrix composite where carbide particles act as the aggregate and a metallic binder serves as the matrix. The process of combining the carbide particles with the binder is referred to as sintering. During this process, the binder eventually will be entering the liquid stage and carbide grains remain in the solid stage. The binder is embedding/cementing the carbide grains and thereby creates the metal matrix composite with its distinct material properties. The naturally ductile metal binder serves to offset the characteristic brittle behavior of the carbide ceramic, thus raising its toughness and durability. Such parameters of carbide can be changed significantly within the carbide manufacturer's sphere of influence, primarily determined by grain size, cobalt content, dotation, and carbon content.

Our products provide optimum performance for a broad range of operations, including contouring, facing, slotting, and ramping. Inserts feature a unique and highly developed combination of substrate and coating configurations that can handle any workpiece material in any machining environment. Dapra is a leading manufacturer of cutting tools for the automotive, die and mold, machining, medical and aerospace industries.
