Abstract

Problems with the conventional linear aerostatic guideway for a PCB drilling machine include deviation from straightness or parallelism tolerance between the granite guideways, and thermal expansion caused by the heat generated from ball screw and the driving system. These factors will result in vibration and affect the positioning accuracy during machine drilling. This paper describes the development of the resistance network method (RNM) for analyzing the static behaviors of aerostatic grooved thrust bearing designed with a disk-spring compensator to hold the table in a suitable position. Comparison is demonstrated between the RNM results and experimental data. Finally, a realizable application of these types of bearing to the linear guideway system for a PCB drilling machine is presented.
