Zhengzhou Yu Hing CNC Cutting Machine Products Co. focused only ten years, a decade sword, specializing in the production of CNC flame, plasma, desktop, intersection Cutting, if demand Zhangqiu CNC flame cutting machines, please feel free to call letter negotiations Preheat CNC flame cutting machines muzzle velocity setting operations summarize the following six considerations. 1. Preheat and flame cutting power (acetylene flow, oxygen flow) should increase with the increase of the plate thickness; 2. Using diffusion-shaped tip and cutting oxygen curtain cutting nozzle plate thickness 20mm or less, the fire power should be large Some, in order to accelerate the leading edge of the incision is heated to ignite, resulting in a higher cutting speed; 3. When cutting thicker steel Bengbu CNC flame cutting machines, flame suitably mild carbonation flame, melt the upper edge of the incision to avoid collapse, but also to so Waiyan longer; 4. single bevel cutting torch tip, because the slag was blown lateral incision CNC flame cutting machines, to supplement the heat, to increase the power of the flame; the higher the carbon content or alloy 5. Cutting At higher levels of the steel elements Qufu CNC flame cutting machine, because it is high lighted, preheat flame of power to a large number; 6. LPG or natural gas as the gas, because the flame temperature is low, warm-up time is longer; cut small parts such as the frequent need to preheat the occasion from the cut, in order to improve cutting efficiency, the flame can be adjusted to oxidizing flame, and then start cutting back to the neutral flame. Bengbu CNC flame cutting machine, CNC flame cutting machine, CNC cutting machine provided by Zhengzhou, Henan Yu Hing Yu Hing NC Products Limited. Zhengzhou Yu-NC Products Ltd. (www.yuxingsk.cn) strong, credible, in Zhengzhou, Henan EDM, wire cutting and other industries has accumulated a large number of loyal customers.
