The Spring Festival Holiday-the biggest festival in China The Spring Festival, falling on the first day of the first lunar month, is the most important festival for the Chinese people. It's the time when all family members get together to celebrate it. People who live away from home will go back, making it the busiest time of the year for transportation systems. We call it 'chunyun', which means 'the transportation during the Spring Festival'，and it can last for about a month. Railway stations, long-distance bus stations, and airports are crowded with home returnees. Many customs accompany the Spring Festival. Fireworks: Burning fireworks used to be the most typical custom on the Spring Festival. However, in recent years, taking security, noise and pollutions factors into account, such an activity was completely or partially forbidden by the government in cities. red envelope: On the morning of the Spring Festival, children will dress up in their new clothes. After extending greetings to their parents, each child will get lucky money as a New Year gift, wrapped up in red envelop. There is many other customs...... Now we have come back to work, we mainly supply different carbide cutting tools like carbide inserts, end mills, carbide rods, carbide saw tips, carbide strips etc. If any interests, pls feel free to contact us!  

Tungsten carbide, not to be confounded with tungsten alloy, which is metal, is the ceramic of choice when it comes to wear and abrasion resistance. Cutting tools for steel and tool steel are made from tungsten carbide. It is also used extensively in the mining industry as a button insert for crushing rocks. The high thermal performance of the tungsten carbide keeps the nozzle tip hot, thus allowing faster printing speed without sacrificing the quality. Tungsten carbide has exceptional wear resistance due to its high hardness. Both the nozzle hole size and height will always stay the same, no matter how long or how hard you use it. Compared to a reference brass nozzle, the tungsten carbide nozzle is much easier to extrude. In fact, the output flow can be increased by around 80% while having the same results.  

1) Tungsten 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 tungsten 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) Tungsten 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 tungsten 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.  

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. Carbide Ball Burrs Carbide Tree Burrs Carbide Inverted Cone Burrs Carbide Pointed Cone & Carbide Round Nose or Ball Nose Burrs Cylinder Burrs. 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
