Description

technical field [0001] The invention relates to a numerically controlled three-dimensional engraving machine, which belongs to the technical field of woodworking machinery. Background technique [0002] In the existing three-dimensional engraving machine technology, when the three-dimensional engraving machine performs horizontal engraving on woodworking workpieces, it is generally completed by the lateral movement of the tool holder equipped with knives. The knives are installed on the water-cooled motor, and the water-cooled motor needs to The tool is driven to rotate at a high speed of more than 20,000 rpm. When engraving a large workpiece or a large amount of engraving, the load on the tool holder is large, which will affect the stability of the operation during the back and forth movement, thereby affecting the machining accuracy of the workpiece. Such as the "three-dimensional engraving machine" of Chinese Patent No. 200810060107.X, the content of the invention [0007] ...

Problems solved by technology

The "clamping the workpiece after the top is close to the turntable" mentioned here is to complete the clamping of workpieces of different lengths. The "three-dimensional engraving machine" of Chinese Patent No. 200810060107. The cylindrical guide rails arranged in parallel are not supported by the table. In such a "suspension" state, when engraving large woodworking workpieces and heavy workpieces, after a long period of longitudinal movement, it is easy to cause deformation of the guide rails and affect the machining accuracy of the workpiece.
