ACTUATOR ARM HAVING SANDWICH BEAM STRUCTURE CAPABLE OF ABSORBING VIBRATION AND NOISE GENERATED BY HIGH-SPEED HORIZONTAL MOVEMENT OF ACTUATOR ARM

摘要

PURPOSE: An actuator arm having a sandwich beam structure capable of absorbing vibration and noise generated by high-speed horizontal movement of the actuator arm is provided to realize a stable servo control environment and user environment. CONSTITUTION: Each beam of an E-block arm(8) to be coupled with a suspension has a slot formed to place a damping element(30) formed of a ductile material, and the damping element is inserted into the slot so that a horizontal buffer part is formed at each suspension-combined part of the E-block arm.
