Voltage & Current of CNC Laser Cutting Machine
Since the 1990s, due to the rapid development of China's socialist market economy, and competition among enterprises is fierce, each firm must be in accordance with their terms, to choose correct advanced manufacturing technology to improve product quality and production efficiency. Therefore, the CNC laser cutting technology gets a rapid development in China.cnc laser cutting machine has characteristics of fast cutting speed, small cut sew in the processing and so on, sometimes it may result in limited actual cutting speed, kerf cut surface is not whole and other phenomena, in order to exclude such problems as CNC plasma cutting machine itself mechanical failure and other factors, the operating CNC plasma cutting machine parameters must be set correctly in the operation process, otherwise it will also affect the actual cutting effect.
Important Power Supply for Laser Cutting Machine
The plasma cutting power supply must have enough high-load voltage so that it can be easily arc and plasma arc steady burning. No-load voltage is generally 120-600V, and the arc column voltage is generally half of the no-load voltage. Arc column voltage can significantly increase the power of the plasma arc, which can increase the cutting speed and cutting the sheet metal of greater thickness. Arc column voltage electrode often by adjusting the gas flow and increase shrinkage is not achieved, but the arc column voltage can not exceed 65% of the no-load voltage, otherwise it will make the plasma arc instable. To increases the power of the plasma arc cutting current also can improve the plasma arc power, but it is subject to the maximum allowable current limit, or else make the plasma arc column thicker and kerf width increased, decreased the electrode life of the laser cutting machine.
Overall of Fabric Laser Cutting Machine
Nowadays, fabric laser cutting machine is widely used in the fabric and cloth industry. As for laser cutting machine, the cut fabric is generally used lens of focus 50mm, the normal speed of single-layer cutting 5 m / min, light intensity is 40%, the good or bad, and the flatness of the pump power and size, cellular floor and light size will affect or destroy the effects. Light intensity and the greater the greater the thermal radiation, thin and light will produce a gap. is currently the biggest problem of cutting is yellowing, put the fabric flat on the cellular chassis, turn on the exhaust fan, in a timely manner to take away the smoke so as to avoid the dust generated from smoking the cutting fabric into yellow, open the air compressor to ensure that the inflatable rural fruit, blow away the impurities in the slotted volatiles and soot blowing with inert gas (nitrogen) would be better.
