A reaming machine includes a machine body; a retractable fixture installed above the machine body and used to press against a workpiece and fix the workpiece; and a vertical wall disposed inside the machine body. Two slide rods are installed to the vertical wall. A slide seat is slidably coupled to the two slide rods. A driving source is fixed to the slide seat. A piston rod is installed to the bottom of the slide seat. A hydraulic cylinder enables the piston rod to move telescopically. The piston rod further enables the driving source to move up and down. A tool seat is installed to the driving source. A reamer is installed at the top of the tool seat and can ream a hole on the workpiece. As the reamed hole faces downward, the wooden dust and debris generated in reaming will fall into the interior of the machine body.
