Description

Technical Field

[0001] The invention relates to the technical field of engraving machines, and in particular to a tool setting device for a three-axis engraving machine. Background Art

[0002] The three-axis engraving machine is a computer-controlled device that uses cutters or other tools to perform operations such as engraving, cutting, and punching on the surface of materials. It mainly moves and processes through three coordinate axes, X-axis, Y-axis, and Z-axis, and can achieve fine engraving effects. The three-axis engraving machine is widely used in woodworking, metal processing, plastic processing, stone engraving, mold manufacturing and other fields.

[0003] At present, the existing technology still has the following areas for improvement: three-axis engraving machines will generate a lot of dust during engraving. Existing three-axis engraving machines basically have no specially configured dust removal and recycling equipment. Dust will accumulate on the engraving parts and workbench, and then be cleaned up uniformly. However, if the dust is not cleaned up in time, it will easily affect the subsequent processing operations and reduce the processing accuracy. Moreover, cleaning by only blowing away the dust will cause a large amount of dust to be scattered in the air, resulting in a poor processing environment and a negative impact on the staff. Existing three-axis engraving machines can generally perform linear motion in the horizontal or vertical direction, but cannot perform motion at other angles. For example, when engraving complex workpieces, they have low flexibility and low versatility. Summary of the invention
