Relationship between Cutting Speed a€?a€?and Cutting Effect of Fiber Laser Cutting Machine

For many electromechanical manufacturing industries, modern laser cutting systems controlled by microcomputer programs can easily cut workpieces of different shapes and sizes, and are often preferred over punching and molding processes; although laser cutting is still slower than Red, but it does not die consumption, no need to repair the mold, but also save the time to replace the mold, thus saving processing costs, reducing production costs, so it is more cost-effective to consider from the overall. Laser cutting without burrs, wrinkles, high precision, better than plasma cutting.
The choice of cutting speed for CNC laser cutting machine is actually very important. The optimum cutting speed range can be selected according to equipment instructions or determined by tests. Due to the thickness and material of the material, the melting point is high and low, and the thermal conductivity is large. Factors such as the surface tension after melting, the cutting speed also changes accordingly.
1. When the speed is extremely low, the arc will even extinguish due to the wide incision. Thus, good cutting quality and cutting speed are inseparable.
2. When the cutting speed is too low, because the cutting point is the anode of the plasma arc, in order to maintain the stability of the arc itself, the anode spot or anode area must find the conduction current place near the kerf closest to the arc, and it will also flow toward the jet. Radiating more heat, so that the incision widens, melted material on both sides of the incision gathered and solidified at the bottom edge, forming a slag difficult to clean, and the upper edge of the incision due to excessive melting and heating to form a rounded corner.
3, the cutting speed is too fast so that the cutting line energy is lower than the required amount, the jet in the slit can not quickly blow the melted cutting melt to form a large rear drag, accompanied by slag slag, incision Surface quality declines.
4. Moderately improved cutting speed can improve the quality of the incision, that is, the incision is slightly narrowed, the incision surface is more even and the deformation can be reduced.

Hydrocarbon And Derivatives

Hydrocarbon and derivatives is a general name for hydrocarbons. The Chinese translation of hydrocarbons is often expressed in a combination of elements and simplification. Hydrocarbons take a fire in carbon and hydrogen goes to the head to form a word. The three groups of hydrocarbons are distinguished by the degree of molecular saturation. Alkanes (alkanes) are saturated hydrocarbons and they are unable to accept hydrogen again. Alkenes is a hydrocarbon that is less hydrogen. Alkene molecules can also have more than one unsaturated double bond, so this type of compound includes diene, three ene,... Wait hydrocarbon and derivatives that are more hydrogen deficient than alkenes are called alkynes (alkynes), which contain three bonds.

Common hydrocarbon and derivatives have methane (methane), propane and butane (lighter oil), isooctane, paraffin. High grade gasoline often boasts of isooctane value, which is inversely proportional to the shock caused by combustion of gasoline in internal combustion engines. The name of polyethylene should be paid attention to. Ethylene polymerization is a high grade Zi Wan (the end may have other groups). Many plant essential oils are alkenes. The compound, such as the ramie (limonene, figure two), is the main component of the oil extruded from the peel of orange and grapefruit. The oil produced by the pine tree contains two isomeric pinene (pinene) and a small amount of single compound. The animal liver has the function of making Sha Xi (squalene). It is the intermediate of bile steroids and some sex hormones. Bonds (regular distribution) of the alkenes. Beta carotene (beta -carotene) has a very long conjugated polyene system in which the single bond and the double bond interreplace on the carbon chain, so it can absorb the visible light waves of the part. Acetylene (Fig. three) is the most familiar and simplest three bond hydrocarbon, which can be obtained by the hydrolysis of calcium carbide. Before the electric lamps were popularized, the roadside stalls were illuminated at night for the use of acetylene.
