Description

Technical Field

[0001] The utility model relates to the technical field of deep hole processing, in particular to a device for accurately processing deep grooves and deep holes. Background Art

[0002] Deep groove and deep hole processing is an important and complex task in the field of mechanical manufacturing. Deep holes usually refer to holes with a ratio of hole length to hole diameter greater than 5, and such holes are relatively difficult to process. Deep grooves may refer to grooves with a large depth or grooves with specific requirements for shape and size.

[0003] The existing deep grooves and deep holes cannot obtain effective and stable support during the processing, which makes the deep hole device prone to shaking during use. At the same time, the drill bit is prone to shaking when drilling or cutting deep grooves and deep holes, which will cause an unstable cutting trajectory, making the size and shape accuracy of the processed holes or grooves unable to meet the requirements, which may cause the workpiece to fail to meet functional requirements during use, and even cause the workpiece to be scrapped. The shaking will cause irregular contact between the drill bit and the workpiece, leaving vibration marks or ripples on the processed surface, which not only affects the aesthetics of the workpiece, but may also reduce its service life and performance.
