Nowadays, it is not possible to meet the increasing demands of machining technology without using carbide blades, and a huge percentage of cutting tools are carbide slitting blades, which are being widely used in various industries. If your business is related to carbide blades, or you are considering whether to add carbide blades to your business, here are a few things you must know about carbide slitting Blades.
How long do carbide blades last?
Before answering this question, I want to tell you that if you find a factory to tell you that his blade can be used for 3 months or can cut 3 million meters and so on, then professionally speaking, this factory must be not rigorous. Because the life of carbide blades in addition to the material, process and other factors controlled by the manufacturer, there is the object to be cut, running time, cutting speed and other uncontrollable factors exist, as shown below, in the same material made of tungsten carbide blades, because of the different cutting speeds, the cutting edge of the cutting edge of the wear condition will be very different.
According to our many years of experience in the industry, in the cutting speed, running time is the same case of a material for cutting, carbide blades life is 10-50 times the high-speed steel blade, and the longer the cutting time the more can reflect the advantages of carbide blades.
Where is the real value of carbide blades?
1) The hardness will not be reduced at high temperature.
2) It is not easy to be worn out after long time use, and the longer it is used, the more it can realize its value.
3) It will not be deformed or broken when it receives high pressure.
4) It will not be bent or deformed even if it is processed into a very sharp cutting edge.
What are the real reasons that make carbide cutting tools expensive?
The two main components of Cemented Carbide are tungsten and cobalt, with the average price of tungsten carbide powder in 2023 year at $38,500 per ton and cobalt powder at $31,000 per ton. While cobalt is not a particularly rare metal, because it is a key material in the anode of lithium-ion batteries, two of the fastest-growing product segments over the past few years have been smartphones and electric vehicles, both of which use rechargeable lithium-ion batteries. When you consider the demand for these products and the well-known companies that make them, it’s no surprise that cobalt is in very short supply for the average tungsten carbide toolmaker.
Debunking the one-size-fits-all notion
Carbide Blades, while adaptable, are not universally suitable for all scenarios. For example, closed contours such as curved surfaces, spherical surfaces, etc. are not recommended for carbide blades, and if used incorrectly, even carbide inserts with these superb properties can become disfigured and make you wonder.
Is it rational to measure the quality of an insert by its weight?
Measuring the quality of tungsten carbide inserts mainly depends on the pure content of tungsten carbide, the density of raw material tungsten carbide is 14.8-14.9, while the density of recycled material tungsten powder is in the range of 14-14.3, we all know that: Weight = Volume * Density, If in the case of the same volume, the more high-quality raw materials, the higher the density, and thus the heavier the weight is, so the use of weight to assess the quality of the case has a certain rationality. Certain rationality. But it must be said that at present in the field of carbide cutting tools, there are some manufacturers to steal the concept of recycled materials, and even add iron powder, ceramic powder and other methods in the density of the case of decreasing by increasing the thickness of the blade to try to weight to meet the standard, so in the procurement of carbide inserts, a blindly to the weight to assess the quality of the quality is not reasonable.
