Cemented Carbide Cutting Tools Bue

Bue by the chip stacking a hard wedge near the cutting edge in front of the cemented carbide cutting tool, it is a region in the Cap II deformation zone (Section II deformation zone refers to the bottom of the chips in contact with the front of the cemented carbide cutting tool to produce plastic deformation) inside, is formed by the friction and deformation of the physical phenomena. In the production of medium carbon steel, mild steel, aluminum, plastic metal car, drilling, reaming, pull and thread processing may occur bue.

Cemented carbide cutting tool process basic law

Cemented carbide cutting tool is a cutting process by cutting movement, the cemented carbide cutting tool from the workpiece cut excess metal layer forming the surface of the chips and the machining process, in the course of deformation carbide cutting tools, forms a chip, resulting in cutting force, cutting heat and cutting temperature, cutting tool wear, and many other phenomena.

If you cut off the re-rolled in apple peel can also be joined together in accordance with the original look. However, metal cutting carbide cutting tools, especially in the continuous cutting of steel, the chip will not just roll up. Not because the chip is too hard, but because the chips will produce changes in the length of the reason. Meanwhile, the chip will be wider, thicker. That is, the cutting elements of different shape under different chips. The chip thickness is several times the original, while the length of the chip fraction of the original. Thus, a cutting speed obtained by cutting chips is equal to a fraction of the cutting chips produced.

How selection the tungsten carbide drawing dies fitting?

Although wiredrawing mode can be used for processing all kinds of steel, copper, tungsten, molybdenum etc metal and alloy material of different materials, but drawing die each have its applicable machining scope, therefore drawing mould material is rational selection of key to ensure successful application to obtain the longest die longevity. Different material wiredrawing molds all have its relatively reasonable processing object.

Tungsten Carbide Nozzle Fitting Advantages

Tungsten carbide nozzle fitting materials include cast iron, ceramic, tungsten carbide, silicone carbide, and boron carbide. Cast iron nozzles are now very rare as they wear out after just 6 to 8 hours. Ceramic nozzles are used only with non aggressive abrasive in light duty equipment and blast cabinets. Tungsten, Silicon, and Boron Carbide are the most popular for the majority of blasting applications due to their long life. Comparisons among tungsten carbide nozzle fitting and other nozzles service life are listed below.

Tungsten Carbide Nozzle Fitting Application

With high speed to wash, well wear resistance, excellent corrosion resistance, tungsten carbide nozzle fitting often be used in agricultural irrigation and urban greening. Used in geological prospecting, machinery tool manufacturing and serves as drill bit in wind drill and electric drills for coal digging Fit for precision lathe are used in nonstop cutting of die-cast iron.

Tungsten carbide nozzle fitting offers long life and economy when rough handling cannot be avoided, and where medium cutting abrasives (glass bead, steel shot & grit, mineral or coal slag) are used. Traditionally, tungsten carbide is the material of choice for general nozzle applications. Tungsten carbide nozzle fitting is widely used in such industries as surface treating, sandblasting and painting, electronics, chemical processes. Tungsten carbide nozzle fitting is also used in different applications like for wire straightening, wire guides and others.

Tungsten carbide nozzle fitting introduce

Tungsten carbide nozzle fitting is made by the precision machining with the tungsten carbide materials (super hard alloy). The hardness reached over HRA90 degree while the anti-bending degree reached over 2300N/mm. On machining tungsten carbide nozzle fitting, we do the precision grinding and surface treatment to achieve Ra0.1 of the bore roughness and the Ra0.025 of the R place of both ends. There is a scientific curvature radius design in the both entrance. This design can ensure a smooth transit of the thread. Due to the overall materials processing, and no elevation in the bore, the phenomenon of easy-bending and plugging has been improved comparing with the ruby nozzle.

Tungsten Carbide Cutter Fitting Description

Tungsten carbide is a chemical compound that contains carbon and tungsten and is similar to titanium carbide. It was originally developed for use as a cutting tool, in machine tools applications, where it still finds wide use today. Cemented tungsten carbide is neither a metal nor is it a ceramic. It is a Cemented although this isn't a widely used term. In most cases, tungsten carbide is simply referred to as carbide.

Tungsten Carbide Cutter FittingTungsten carbide alloys are prepared by reacting carbon and tungsten at a temperature of between 1400-2000C. The other method involves using a patented fluid bed process to mix Hydrogen and tungsten elements at a temperature of not less than 900C. Other methods are by the use of vapor deposition, which are still under investigation.

Our company has in its possession an advanced production line for manufacturing dies and moulds and a production line for post machined cemented carbide products. We can also supply tailor-made products of various specifications based on the requirements of our customers.

We supply tungsten carbide wear part, blanks, rod, plate, tips, drill bits, saw tips, tools, insert, blade, and dies etc tungsten carbide products. Please contact with our sales department for more details.

Tungsten Carbide Cutter Fitting Application

You've never seen anything like these incredible cutters. They're made of virtually indestructible tungsten carbide welded to steel shanks. They'll last for years and they won't load up, break down or overheat like ordinary steel cutters. Use on all woods, fiberglass, stone, ceramic or plastic (not recommended for use on metal). 1/8 inch shanks fit in hand drills, rotary tools and drill presses.

Tungsten carbide cutter fitting are used for shaping, smoothing, and material removal. Use on hardened steel, cast iron, nonferrous metals, fired ceramics, tungsten carbide cutterplastics,hardwoods, and other hard materials. Not for use on floor tiles.

Different Kinds of Tungsten Carbide Drill Fitting

As indicated earlier, there are different kinds of carbide drills. Essentially, there are the solid and the tipped. A solid tungsten carbide drill fitting is one in which the whole bit is made of carbide. This is contrasted with the carbide tipped drill bit, where just the tip of the bit is carbide, and the rest might be of the more common steel. There are advantages and disadvantages to the different kinds. 

Advantages of Tungsten Carbide Drill Fitting

One of the advantages of tungsten carbide drill fitting over the more common steel bit, is that they last longer, so long as nothing drastically wrong happens. Drills experience “Wear and tear” because the heat generated due to the friction between the bit and the surface being penetrated, causes the dulling of the bit. As a result, the drill bit needs regrinding from time to time, to maintain it’s cutting edge. However, there is a limited number of times that regrinding can be done before the drill becomes effectively useless. There is also the matter of the structural integrity of the bit, which gets compromised due to the repeated heating and cooling that the bit undergoes as it is put to work. As tungsten carbide drill fitting are tougher and more durable than their steel counterparts, they do not deteriorate as easily, and therefore have a longer lifespan, up to 25 times as much.

To appreciate another advantage of tungsten carbide drill fitting, we need to understand what is meant by drill tolerance. The tolerance of a drill basically is a measure that indicates the accuracy one can expect from the drill bit. It in effect is the difference between the diameter of the bit and the diameter of the largest expected hole generated from actually using the bit. The tolerance is associated with the size of the drill bit, as well as the type. As would be expected from the explanation of what tolerance refers to, the lower it is, the more accurate the bit. Tungsten carbide drill fittng have the lowest tolerances and are therefore the choice of drills for any task that requires high precision.
