Description

Technical Field

[0001] The utility model relates to the technical field of precision mechanical processing, in particular to a cutting device for precision mechanical processing. Background Art

[0002] Precision machining is a process of changing the shape, size or performance of a workpiece by using machining machinery. Cutting refers to the use of cutting tools (including cutters, grinders and abrasives) to cut off the excess material layer on the blank or workpiece into chips, so that the workpiece obtains the specified geometric shape, size and surface quality.

[0003] According to the search, the Chinese patent document, authorization announcement number CN219786717U, discloses a cutting device for precision machining. The device can cut the clamped objects at multiple angles by setting up a multi-angle cutting mechanism, using a first robotic arm, a second robotic arm and a steering cutter. The device can block the debris in the cutting process by setting up a protective cover, but the protective cover also limits the observation field of view to a certain extent, and it is impossible to see the specific workpiece processing process. Therefore, when problems occur in the workpiece processing, it cannot be adjusted in time, and the device can only adjust the front and rear position of the cutting edge, so it can only cut one direction of the workpiece, which reduces the applicability of the device body. Therefore, it is necessary to improve the existing device to meet actual needs. Utility Model Content
