Description

Technical Field

[0001] The utility model relates to the technical field of deep hole processing applications, in particular to a stepping deep hole drill. Background Art

[0002] In the field of engineering technology, in many cases, it is necessary to drill holes in equipment, facilities or their components. The most common way to perform drilling operations is to use a drill bit. Simply put, the drill bit is aligned with the position where the hole needs to be drilled, and a driving device is used to drive the drill bit to rotate and drill. The drill bit usually has a shank for connecting the driving device and a slender drill rod part. When drilling, the drill rod part is screwed into the position where the hole needs to be drilled to form a hole. A deep hole drill is a drill bit specifically used for processing deep holes. In machining, a hole with a ratio of hole depth to hole diameter greater than 6 is usually called a deep hole.

[0003] When the existing deep hole drill processing equipment is performing processing operations, it is generally semi-automatic processing operations, which require workers to continuously load and feed the processing materials, thereby reducing the processing efficiency of the materials. And when performing deep hole processing on the materials, the internal chips generated cannot be cleaned in time, so manual cleaning is required later, which not only increases the labor intensity but also reduces the overall processing efficiency. Therefore, the utility model proposes a stepping deep hole drill. Summary of the Utility Model
