Development of the Axial Splitting Process for Small Diameter Brass Tubes

We developed the equipment for splitting the long and small diameter tube, with using a splitting tool which was previously developed [1]. The splitting target is brass tube. Its length is about 500mm and the diameter is about 19mm. Because of the high aspect ratio, it is considered to cause a buckling easily. The developed equipment has a special gripping device for the long brass tube. Also the end of the long brass tube is gripped by the unique jig. As a result, it is shown that the brass tube (500mm length, 19mm of diameter and the thickness of the wall is 1.2mm) can be split in axial direction along its full length by using the developed tool and equipment.
