加工汽轮机、燃汽轮机、压气机、水轮机叶片的原工艺一般是:1.精铸或精锻毛坯;2.手工砂轮打磨,3.用模板测量规定截面;4.砂布轮手工拋光。其中,第2、3道工序反复交替进行,直到用模板测量达到图纸要求。这种方法,不仅效率低、精度难以保证,而且劳动强度大、工作环境恶劣。为此,可采用改制出五坐标联动计算机数控砂带磨床对叶片进行加工。 Processing of steam turbines, gas turbines, compressors, turbine blades of the original process is generally: 1. Casting or precision forging rough; 2 hand grinding, 3 with a template to measure the required cross section; 4 Shabu wheel manual polishing. Among them, the first 2, 3 procedures repeated alternately, until the template to meet the drawings requirements. This method, not only inefficient, difficult to guarantee the accuracy, and labor-intensive, poor working conditions. To this end, the system can be transformed into a five-coordinate computer CNC belt grinding machine for processing leaves.
