The invention belongs to the field of a wood machining, and particularly relates to a double-sided polishing machine for a wood used for manufacturing furniture. The invention aims to solve a technical problem that polishing efficiency can be improved and a large amount of dust generated in the polishing process can be avoided by providing the double-sided polishing machine for the wood used for manufacturing the furniture and in order to solve the technical problem, the invention provides the double-sided polishing machine for the wood used for manufacturing the furniture. The double-sided polishing machine comprises a mounting plate, a bottom plate, a motor, a first belt wheel, a first rotating shaft, a first bearing seat, a first connecting plate, the second connecting plate, the secondbearing seat, the second rotating shaft, the second belt wheel, a first flat belt, a supporting seat and a guide roller and the like. The mounting plate is fixedly connected with one side part of thebottom plate, a first dustproof frame is fixedly connected with the mounting plate through the second connecting plate, and the second dustproof frame is fixedly connected with the mounting plate through the first connecting plate. According to the double-sided polishing machine, the wood polishing efficiency is improved, and an effect that not too much dust is generated in the polishing processis ensured.
