Description

Technical Field

[0001] The utility model relates to the technical field of engraving machines, in particular to an engraving machine with a multiple positioning structure. Background Art

[0002] Engraving is a combination of drilling and milling in terms of processing principle. The engraving machine has multiple data input modes that can be used according to needs. Computer engraving machines are divided into two categories: laser engraving and mechanical engraving. Both categories are divided into high-power and low-power. The application range of engraving machines is very wide. Engraving machines are needed for acrylic processing. During the use of existing acrylic engraving machines, the positioning stability effect of acrylic engraving is poor due to the relatively simple structure of the components for positioning acrylic. Acrylic is prone to slight deviation, which affects the reliability of engraving processing. Therefore, we propose an engraving machine with a multiple positioning structure. Utility Model Content
