What are Tungsten Carbide Rotary Burrs? ZhuZhou Apple Carbide Produced Tungsten Carbide Rotary Burrs, often referred to as rotary files or die grinder bits are used for cutting, shaping, and grinding, and for the removal of sharp edges, burrs and excess material (deburring). What Materials could be used for Carbide Burrs ? Tungsten Carbide Rotary Burrs can be used on a multitude of materials: metals including steel, aluminum and cast iron, all types of wood, acrylics, fibreglass and plastics. Carbide burrs are also perfect for working on softer metals such as gold, platinum and silver as they last a long time with no chipping or breaking. Carbide Burrs Commonly Come in Two Cuts; Single Cut and Double Cut Single cut (one flute) carbide burrs have a right handed (Up cut) spiral flute. These tend to be used with stainless steel, hardened steel, copper, cast iron, and ferrous metals and will remove material quickly. Use for heavy stock removal, milling, deburring and cleaning. Double cut carbide burrs tend to be used on ferrous and non ferrous metals, aluminium, soft steel and also for all non-metal materials such as plastics and wood. They have more cutting edges and will remove material faster. These are the most popular cut and will see you through most applications. Various Shapes of Carbide Burrs Making a decision on what shape to use will depend on the profile or cut you are looking to achieve.These different shaped burs will get into many a nook and cranny and produce some interesting profiles.

Round Nose/Ball nose/End Cut Oval Burrs Flame Burrs Oblate Spheroid Countersink Burrs Carbide Burrs are Harder than HSS Burrs Good quality Carbide Burrs are machine ground from a specially chosen grade of carbide. Due to the extreme hardness of the Tungsten Carbide they can be used on much more demanding jobs than HSS (High Speed Steel). Carbide Burrs also perform better at higher temperatures than HSS so you can run them hotter, for longer. If you have problem for choosing a corre

What To Consider When Thinking About Solid Carbide End Mill Machining The selection of geometries and coating for solid carbide end mills can be a confusing, but evaluating the operation will determine which end mills are best for the job. One of the most confusing aspects about using solid carbide end mills is the selection of many types of geometries and coatings. By understanding what geometries and coatings can or cannot do makes selection as easy as one, two, three. When first deciding which end mill to use, thoroughly evaluate the operation along with the material that needs to be employed to get the desired shape needed. The next step is deciding what geometry will work best. For example, when doing a slotting operation, unless doing a light cut of about .2D or less, it is best to use a two- or three-fluted end mill. The general rule is use less flutes for deeper cuts, with four or higher flutes for light cuts. The reason for this is the venerability of chip packing that can lead to destruction of the end mill. If the machine and program have the ability to trochoid mill, a method which is done by engaging circular arcs using an end mill smaller than the slot width, a larger number of flutes can be employed. Since the end mill is basically periphery cutting, less heat and forces allow for longer tool life, higher tolerance finishes and increased production over the same amount of time it would take using the conventional method. When a periphery cut or side mill operation is part of the application and metal removal is of concern, employ a larger number fluted end mill with four, six, even eight teeth. Knowing the basics of geometries and coatings and understanding what they can and cannot do is the first step to helping you decide which end mill should perform best for your application.  

Precautions for using cemented carbide tools 1) Cemented carbide is a hard and brittle material, which is brittle and damaged under excessive force or some specific local stress, and has a sharp edge. 2) Most cemented carbides use tungsten and cobalt as the main components and have a high density. They should be handled with heavy objects during transportation and storage, and handled with care. 3) Cemented carbide and steel have different thermal expansion coefficients. In order to avoid stress concentration cracking, attention should be paid to welding at an appropriate temperature. 4) Carbide cutting tools should be stored in a dry environment away from harsh atmospheres. 5) During the cutting process of cemented carbide tools, chips and chips are constantly produced. Please prepare necessary labor protection supplies before machining. 6) If you use coolant or dust suction device in the cutting process, for the purpose of inserting the machine tool and cutting tool, please use cutting fluid or dust suction device correctly. 7) Please stop using the tool that has cracks during processing. 8) Continuous use of cemented carbide cutting tools will cause the cutting edge to become dull and reduce the strength. Please do not let non-professionals grind. 9) Please keep the worn out alloy cutters and the fragments of alloy cutters properly to avoid hurting others.  

Carbide Carbide is a term which indicates a compound of carbon and some other element or group of elements. When you hear anyone mentioning about this chemical compound, that person is generally referring to calcium or tungsten carbide. Uses of Carbide Similarly, there are other types too which serve different purposes. For instance, there is silicon, aluminium, and boron. Calcium Carbide Calcium carbide is a substance which is produced by an industrial process. The molecular formula of this is CaC2. After looking at this formula, one can easily figure out that one molecule of this consists of one atom of calcium and two atoms of carbon. Tungsten Carbide It appears to be grey in colour, which is like a fine powder. If you look at the molecular formula, you will find in comprises of tungsten and carbon in equal quantities. When we press it, it creates a particularly hard substance which serves different purposes. For instance, the armour-piercing weaponry which the people in military use is made with the help of this chemical compound only. Silicon Carbide Next, we have this chemical compound which has a molecular formula of SiC. Thus, this molecular formula denotes that it contains one atom of silicon and one of carbon. We also refer to it as carborundum. It arises in nature as the awfully rare mineral called moissanite. When you manufacture and fuse together the grains of this chemical compound, it results in the formation of quite a hard and durable substance. Therefore, we use it in products like car brakes, turbine bearings and more. Particular kinds of seals and bearings also contain this. Similarly, its large crystals are grown artificially as the diamond imitation jewel moissanite. Boron Carbide This is one of the hardest synthetic materials which are a ceramic substance. It is made up of four atoms of  boron and one atom of carbon. We use it in tank armour, cutting tools, security padlocks and more. We also use it in nuclear reactors because of the chemical reaction of this compound. Zhuzhou Apple Carbide Tools Co., Ltd. is a professional manufacturer of tungsten carbide products in China.
