The supporting structure of the single-face
polishing machine comprises a box body, the box body comprises a lower box body and an upper box body arranged on the lower box body, a supporting column is connected between the lower box body and the upper box body to form an up-down split type supporting structure, a lower
polishing disc assembly is arranged in the middle of the lower box body, and a lower
polishing disc assembly is arranged in the middle of the lower box body. An upper polishing head
assembly is arranged above the lower polishing
disc assembly, and the upper polishing head
assembly is arranged on the upper box body and used for pressurizing and polishing a workpiece on the lower polishing disc
assembly. The supporting structure of the single-face polishing
machine adopts upper and lower split type supporting, can avoid an upper polishing head shaft
system resonance point, eliminates equipment vibration, improves the perpendicularity of an upper polishing head
system and a lower polishing disc, guarantees the
machining precision, and meanwhile increases the equipment
machining space.
