The use of 230*3*22 sharp cutting off wheel is mainly due to its stable performance, but its performance is due to its own influence. So, what are the performance factors that can affect it?
First, the influence of molybdenum: Both molybdenum and chromium are elements that form and stabilize ferrite and enlarge the ferrite phase region. The ability of molybdenum to form ferrite is comparable to that of chromium. Molybdenum also promotes the intermetallic phase in austenitic stainless steels, such as σ phase, κ phase, and Laves equivalent precipitation, which will adversely affect the corrosion resistance and mechanical properties of steel, especially the plasticity and toughness.
Second, the effect of chromium: chromium is the most important alloying element in austenitic stainless steel, the austenitic stainless steel's rust and corrosion resistance are mainly due to the promotion of steel passivation under the action of the chrome The result of keeping the steel stable and passive. The most important influence of chromium on the properties of austenitic stainless steel is corrosion resistance. The main performance is: chromium improves the oxidation resistance of steel and the performance of acid chloride medium; under the combination of nickel and molybdenum and copper, chromium improves steel resistance. The properties of reducing media, organic acids, urea, and alkali media; chromium also improves the resistance of steel to localized corrosion, such as intergranular corrosion.
3. Effect of nickel: Nickel is an element that strongly stabilizes austenite and enlarges the austenite phase region. With the increase of nickel content, residual ferrite can be completely eliminated, and the tendency of σ phase formation is significantly reduced; The temperature of the meta carbon-transfer hydrocarbon is lowered, and even the λ→M phase transition may not occur, but the increase of the nickel content reduces the solubility of carbon in the austenitic stainless steel, thereby increasing the tendency of carbide precipitation. Moreover, the addition of nickel can further improve its toughness. Nickel also significantly reduces the cold work hardening tendency of austenitic stainless steels, mainly due to the increased austenite stability, which reduces or eliminates martensite transformation during cold working.
For ultra-thin cutting blades, there are many factors that affect its cutting performance, and its shape and balance are two of them. So, what are the effects of these two factors on its cutting performance?
1. When the end of the cutting piece jumps large, it swings back and forth during cutting, and the cutting width is large. The material to be cut is unnecessarily consumed, and the consumption of the cut piece is naturally large and has a large influence. When the cutting piece has a large radial runout, the vibration is large at the initial stage of cutting, which tends to cause the 230*3*22 sharp cutting off wheel to fall off, affecting the strength and cutting, but is automatically trimmed after cutting, and the overall influence is small.
2. When the thickness is large, the slit is wide and the cutting piece is consumed greatly; when the strength is guaranteed, the smaller the thickness, the better, which not only saves the material of the fiber cutting disc Chinese supplier but also saves the material to be cut; when the flatness is large, the width of the slit is determined by the thickest part. The strength is determined by the thinnest part, and the wear is large and the vibration is large, which affects the entire cutting process. When the thickness of the cutting piece is large in the middle and the thickness on the side is small, the side of the 230*3*22 sharp cutting off wheel is ground and the workpiece is cut during the cutting process.
Third, the more unbalanced, the vibration in the cutting is large, easy to cause the cutting piece to fall off, affecting the strength.
