Abstract
An abrasive apparatus of a sander is provided. The abrasive apparatus is disposed above a worktable of the sander and includes a base and a lift unit. At least one abrasive wheel is provided in the base. The base has a top formed with at least one slot. The lift unit is disposed on the abrasive wheel to bring the abrasive wheel to move up so that an abrasive surface of the abrasive wheel passes through the slot of the base and protrudes from the base for the top of the base to sand the side of a workpiece. The cutting width of the sander can be extended to enhance the use of the sander, so the manufacturing process can be shortened to increase the production efficiency.
