生产喷气发动机和涡轮机时,须在部件上钻无数小的冷却孔道来降低高温,生产这些部件时要以很小的公差钻几千个冷却孔道,并且对它们的位置、方向和直径的要求都非常严格。由于部件材料的融点很高,因此至今很难用普通的机械方法加工出这些直径小的深孔。许多制造商已经想到用激光来解决问题,实际上已经这样做了。用激光的原因在于它的打孔速度 In the production of jet engines and turbines, numerous small cooling ducts have to be drilled into the components to reduce the high temperatures required to produce thousands of cooling ducts with a small tolerance when producing these components, all of which are required for their location, orientation and diameter Very strict. Due to the high melting point of the component materials, it has so far been difficult to machine these small diameter deep holes by conventional mechanical methods. Many manufacturers have thought of using laser to solve the problem, in fact, have done so. The reason for using a laser is its punching speed
