火焰精密切割技术是近几年在氧乙炔焰切割工艺的基础上发展起来的一项新工艺,在机械、造船、交通、建筑、石化等工业部门,具有广泛的推广应用意义,它能大量节约设备、材料,提高劳动生产率,改善劳动条件,是实现成形加工的重要手段之一。优质下料能获得相当于机械加工中▽_3级光洁度的切断面和良好的几何形状。由于优质割咀的排渣能力强,风线挺直而清晰,故可提高切割速度,这就使得切割口位材料的物理机械性能变化不大,对焊接和机械加工影响甚微。因此,对自由尺寸和要求不高
Flame precision cutting technology is a new technology developed in recent years based on oxyacetylene flame cutting technology. It has a wide range of promotion and application significance in machinery, shipbuilding, transportation, construction, petrochemical and other industrial sectors, it can save a lot of Equipment, materials, improve labor productivity, improve working conditions, is one of the important means to achieve forming. High-quality blanking results in a cross-section with good geometry equivalent to ▽ _3 finish in machining. Due to the high cutting capacity of the cutting Tsui, the wind straight and clear, it can increase the cutting speed, which makes the cutting port material physical and mechanical properties change little, little impact on the welding and machining. Therefore, the free size and requirements are not high
