Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grinders, in particular to a grinder that is easy to use. Background Art
[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, while a few use other grinding tools such as oilstones, sanding belts, and free abrasives for processing. When using a traditional grinder, the workpiece is usually held manually and brought close to the grinding disc on the grinder, and the grinding disc is used to grind the position on the workpiece that needs to be ground. When the workpiece is held close to the grinding disc, the workpiece may be over-grinded or the workpiece needs to be picked up and measured every time it is ground a little, resulting in a cumbersome grinding process and low precision. In addition, when chamfering the corners of the workpiece, the workpiece is manually tilted to bring the corners close to the grinding disc, resulting in large errors.
