Lubrication Treatment for Stabilizing Spindle Impact Balancing Process in Hard Disk Mechanisms

Abstract

In higher TPI and faster rpm drives, rotational spindle balancing is very vital for its performance and user amenity. We have developed impact balancing which uses piezoelectric impact hammer without additional mass. To obtain a stable yield, the friction of mechanical parts disturbed, hence we tried lubrication treatment for the mechanical parts. Using very thin fluorocarbon lubricant, the friction between mechanical parts diminished and became more stable, and the yield increased. We subsequently reported our experimental results.
