Abstract
A machining device for processing metal hanging rod of blinds having a machine platform, two fixing bases, and a retaining unit. A top of the machine platform has a holding groove for the two fixing bases. A middle section of the machine platform has an internally threaded hole for a reversible bolt of a motor. A bottom of the machine platform has a registration groove for the retaining unit to be guided via bearings. The fixing bases, each having a spring and a tapered pivot support, are adjustable to fit the length of a metal hanging rod. A sand wheel, contacting the metal hanging rod at one point and turned on to vibrate said springs, cuts out an interlaced wavy pattern on a periphery of the metal hanging rod. Alternatively, two concentric sand wheels form two contact points, producing double-layered interlaced wavy pattern on the metal hanging rod.
