Notices for Flame Cutting Machine
In the process of cutting with numerical control flame cutting machine, there are often different kinds of cutting defects. In order to improve the cutting quality, the key points of controlling the quality under different cutting conditions are briefly introduced.
1. Points for Attention in Forging Cutting
Because the oxide skin on the surface of forgings is thicker and the burning point of oxide skin is higher than the melting point, cutting interruption is easy to occur in the cutting process, resulting in the decline of cutting quality and efficiency. Therefore, in order to improve the cutting speed and quality, the oxide skin on the upper and lower surfaces of the cutting area should be removed before cutting forgings.
2. Key Points of Deformation Prevention in Cutting Tooth Plate of Rolling Billet Cold Bed
How to control the workpiece deformation is very important in cutting. For example, according to the routine cutting route, the workpiece deformation and overshoot will be caused, even if the shaping is difficult to meet the size requirements, and eventually the product will be scrapped. Therefore, it is very important to arrange gas cutting routes reasonably.
