摘要

Researches done to date indicate that burning a series of microtexture into the working surface of friction units with a laser can remarkably improve the lubrication characteristics between the friction units, prolong the service life of the friction units, and reduce energy consuming. Based on this purpose, a multi-friction units working surface YAG laser micro-texturing system is studied and developed which is composed of a 15W@TEM_(00) Q-CW diode-pumped solid-state (DPSS) Nd:YAG laser, a servo drive three-dimensional worktable and a CNC system. The operating principle of micro-texturing system and the control method of the CNC system are introduced. In the CNC system, a high precision increment optical-electrical encoder is fixed to the revolving axis to detect the position that the axis has revolved. And the signal from increment encoder is input into a self-made encoder counter card. After counting and dividing the signal's frequency, a Q-switch control signal is output to the Q-switch driver to control single laser pulse output. Thus, the Q-switch and the servo drive motion control system are in synchronization control and pattern controlled microtexture is acquired. And the control method meets the requirement of high efficiency and low cost. Currently, the YAG laser micro-texturing system is being used to process cylinder jacket and mechanical seal.
