    • PROBLEM TO BE SOLVED: To provide a method for manufacturing the compressor rotor blade tip of an aircraft gas turbine. SOLUTION: With a method for finish-machining the blade tips 2 of rotor wheels made in BLISK design, in particular of multi-stage compressor rotors 1 for the aircraft gas turbines or industrial gas turbines, the rotor wheel, or also the multi-stage compressor rotor, restrained in a clamping fixture is machined, blade 3 by blade 3 and stage 4 by stage 4, at the blade tips by means of a conical cutter 5 while a cutting edge 7 of the conical cutter is oriented tangentially to the outside surface of the rotor wheel or the compressor rotor and routed on the blade tip essentially along the centerline thereof, with cutting force being introduced vertically to a tool axis 11 and in the stiffest direction of the blade, i.e. the centerline of a blade cross-section and a vertical axis extending from the centerline. The cutting action and force introduction of the conical cutter at the blade tip are such that blade tips with a geometrically precisely defined edge can be produced, thereby dispensing with time-consuming and cost-intensive assembly and disassembly of damping means likely leading to distortion and dimensional deviations of the blades.

    • 要解决的问题:提供一种用于制造飞机燃气轮机的压缩机转子叶片尖端的方法。 解决方案:使用用于对BLISK设计的转子轮的叶片尖端2进行精加工的方法,特别是用于飞机燃气轮机或工业燃气轮机的多级压缩机转子1,转子轮,或者 夹紧夹具中的多级压缩机转子通过刀片3和阶段4由工作台4通过锥形切割器5在叶片尖端处被加工,同时锥形切割器的切割刃7切向地定向于 转子轮或压缩机转子的外表面,并且基本上沿其中心线路线在叶片尖端上,切割力垂直地引导到工具轴线11并且在叶片的最硬方向上,即叶片横截面的中心线 和从中心线延伸的垂直轴。 锥形切割器在叶片尖端处的切割动作和力的引入使得可以产生具有几何精确限定的边缘的叶片尖端,从而分配耗时且成本高昂的组装和拆卸可能导致变形的阻尼装置, 叶片的尺寸偏差。 版权所有(C)2010,JPO&INPIT
