Development of a CNC 5-kW CO2 laser processing equipment

摘要

Abstract: This paper introduces the fundamental compositions and functions of a newly developed 5KW CO$-2$/ laser processing equipment CGJ-93 controlled by microcomputer in Changchun Institute of Optics and Fine Mechanics. The laser processing equipment consists of a 5KW CO$-2$/ laser, multifunction beam guidance systems, modular processing machine, water cooling system and CNC systems. The equipment has the ability to heat-treat not only the internal holes and outer circular surfaces but also space holes and three dimensional curved surfaces. The equipment can heat-treat workpieces up to 3000mm length, 1500mm diameter and 3000kg weight. The longitudinal table allows moving speed of 0.8-12000mm per minute with 3600mm effective moving range and 0.069mm position accuracy. The transverse table allows moving speed of 5-12000mm per minute with 1000mm effective moving range and 0.028mm position accuracy. The laser head allows longitudinal moving speed of 0.1-12000mm per minute. Its effective moving range and position accuracy are 540mm and 0.03mm respectively. !6
