A scroll manufacturing tool for finishing a spiral element (141) of a preformed scroll (14) including a working member (11) having an end plate (111) on which a first involute element (112) extending is affixed, a second involute element (12) interfitting to the first involute element (112) to form a radial gap therebetween and having a plurality of pins (121), and an adjusting plate (13) rotatably mounted on a shaft (113) on the back side of the end plate (111) and fixedly connected with the second involute element (12) by pins (121) extending through arcuate holes (114) formed in the end plate. The axial end portions of the first and second involute elements (112, 12) are provided with teeth (115, 122) extending along respective involute elements (112, 12) to finish both side surfaces of the spiral element (141) urged into the radial gap. The gap between the facing teeth (115, 122) can be adjusted by relative rotation of the adjusting plate (13) and the working member (11). |
