Description

Technical Field

[0001] This utility model relates to the field of stone carving technology, specifically a cylindrical stone carving machine with a gantry movement. Background Technology

[0002] Stone carving is an ancient and exquisite art form that involves shaping hard stone into various forms and patterns. This art form dates back to prehistoric times and has been widely used in architectural decoration, monuments, sculptures, and other fields. As an ancient and refined art form, stone carving continues to play an important role in architecture, art, and other fields to this day.

[0003] Traditional stone carving is done manually by workers, which usually takes half a month or even longer to produce a product. The labor cost is relatively high. Therefore, we designed a gantry-type cylindrical stone carving machine that is more compact, has higher production efficiency, is easier to operate, and has a wider range of applications compared to the existing gantry-type multi-head carving machine. It is also more convenient and faster to load and unload large and heavy rotating objects and is less prone to collisions. This solves the above problems. Utility Model Content
