Abstract


This paper indicates the enhanced method of producing components of textile machines. The use of Nd-YAG laser beam in the manufacturing process improves quality of the components. The bottom rollers are one of the few important parts of textile machine giving quality yarns. The objective is to harden the complex shaped  bottom roller and to eliminate post processes like grinding, bend removing followed by transportations and thereby made to run concentrically and giving quality yarn. The traditional processes of flame hardening, gas carburizing, nitriding, and induction hardening partially fulfil the requirements of hardness parameters on the roller. The laser hardening process was performed with 3 axes CNC machine attached with fiber optic laser head and servo controlled rotary chuck and suitable fixtures. The results of laser surface hardening show improved hardness, microstructure and uniform case depth on all contours and very less warping. The laser treated roller subjected to the normal working conditions on a textile machine run with almost concentric for longer life with which the yarn quality can be improved.
