Carbide Cutting Tool Advantages And More Widely Used
Carbide Cutting Tool features
The so-called hard alloy is a high hardness of refractory metal carbide and a specific binder sintered powder metallurgy products. Its heat resistance is good, capable of up to 800 ~ 1000 ℃ cutting temperature. At the same time because of the hardness of carbide cutting tools, sharpness, wear resistance, durability than high-speed steel tool, its shape is more high-speed steel can not be compared, and the other. Carbide Cutting Tool long life, good processing quality, high precision, so in the furniture and wood, building materials processing industry has been widely used carbide cutting tools for wood processing, cutting all kinds of wood, plywood, particleboard, high school MDF, man-made Marble, steel, aluminum and other different materials, which can not only rough processing can be finished, not only can be used for processing all kinds of plate, but also can be used for processing all kinds of materials, veneer sheet.
Carbide Cutting Tool types, selection and grinding
Although the advantages of carbide cutting tools and more widely used, but with a variety of veneer sheet, man-made sheet, the increase in the type of building materials, as well as the different requirements of each manufacturer must choose the appropriate carbide cutting tools to adapt to different Cutting materials and different product quality requirements.
According to the quality and processing, carbide cutting tools can be divided into high, medium and low three grades.
High - grade carbide cutting tools
Mainly including Germany, Japan, Italy and other countries produced a few brands, characterized by:
As a result of the use of alloy quality, most of the production of laser cutting, so the blade is smooth and can be used continuously for many years, both durable, life of ordinary domestic tools 4 to 5 times;
All the cutting edge of the tool by the automatic CNC grinding equipment according to the scheduled process to produce a completely consistent wire profile, the end of the electronic centrifugal balance adjustment, the knife shaft hole after grinding, can achieve a smooth and vibration-free cutting, and thus high precision, High precision, good finish, cutting a molding, no longer trimming, can completely solve the wood, plywood, particleboard, medium density board flash, veneer board gnawing edge, collapse edge, paste edge and other wood processing industry common Kind of problem;
Easy to use when used, light, told the operation of the tool is not deformed, low noise design, and can effectively discharge chips and dust;
The price is more expensive, generally used for high quality requirements of the plate, furniture processing.
Carbide is a very good material, because it is very good material will be widely used, so the carbide is very famous, but the production of carbide is quite difficult, in fact, the most important issue is The tool in the grinding process will appear cracks in the phenomenon, which is a great technical problems, but although difficult, it is not can not be overcome, as long as I introduced the following points to note, I believe that is to overcome the tool grinding crack Of the phenomenon, first of all we do not open the wind pressure is too large,Carbide Cutting Tool generally 4-6 kg wind pressure appropriate. But the diamond grinding wheel is expensive, easy to repair after wear and tear, so many factories still use ordinary grinding wheel grinding. Carbide is hard and brittle material, grinding wheel vibration due to the impact of the tool to the impact load, prone to vibration; the same time, the grinding area of the instantaneous temperature and cooling so that thermal stress may exceed the strength limit of carbide recovery and heat crack. The general principle of the use of different rocks is that the alloy is not broken under the conditions of the higher hardness of the alloy the better. But the diamond grinding wheel is expensive, easy to repair after wear and tear, so many factories still use ordinary grinding wheel grinding. Drilling process, we should pay attention to the rock gap, caused by the huge impact of broken alloy and stuck drill pipe. In drilling high hardness rock when the use of high cobalt grade alloy, impact resistance, the alloy is not easy debris, out of pieces. The above-mentioned grinding wheel inside the open field covered with molybdenum disulfide, the abrasive can play a role in lubrication, so that the wheel chip is good, not easy to plug.
