Description

Technical Field

[0001] This utility model relates to the field of belt sander technology, specifically a belt sander with a single / dual station adjustment structure. Background Technology

[0002] A belt sander is a common processing equipment for both metal and non-metal materials, primarily used for grinding and cutting. It operates based on the grinding and cutting principles of a sanding belt, using the rotation and friction of the belt to grind and finish the workpiece. Belt sanders can be categorized into several types, including benchtop belt sanders, vertical belt sanders, push-type belt sanders, and dust-collecting belt sanders.
