Description

Technical Field

[0001] The present invention relates to the technical field of metal casting processing, and more specifically, to a cutting device for precision machining of metal castings and its processing technology. Background Art

[0002] Metal castings are metal formed objects obtained by various casting methods, that is, the smelted liquid metal is injected into a pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, through subsequent processing means such as grinding, an object with a certain shape, size and performance is obtained. In the field of precision machining of metal castings, cutting devices are an indispensable part.

For workpieces with complex shapes or requiring multi-angle cutting, frequently adjusting the position of the workpiece not only takes time and effort, but also reduces production efficiency. In addition, in some cases, due to the large size or heavy weight of the workpiece, manual adjustment of the position becomes very difficult or even impossible. Summary of the Invention
