Abstract
Description
Technical Field
[0001] The utility model relates to the field of mechanical processing, in particular to a dust suction structure and a turntable. Background Art
[0002] Currently, laser grinding can thin the workpiece. However, dust will be generated during the thinning process. In order to reduce the impact of dust on the processing environment, an air suction pipe is added to the side of the workpiece to be processed during the processing to suck away the dust. However, with this operation method, some dust will still not be sucked away, and the dust extraction effect is not good enough.
[0003] In addition, when multiple workpieces need to be clamped at the same time for processing, the workpieces generally need to be mounted on a turntable. In this way, during laser grinding, dust may be scattered onto other workpieces to be processed or completed, which is not conducive to creating a clean processing environment. Utility Model Content
