Description

a boring tool

technical field

The utility model relates to the fields of machining and the like, in particular to a boring tool.

Background technique

Boring tool is a kind of hole processing tool, generally with round handle, and there are also larger workpieces with square tool holders, which are generally found in vertical lathes. The most commonly used occasions are inner hole processing, hole reaming, profiling, etc. But not only the inner hole can be processed, but the outer circle of the end face can also be processed.

When installing knives, pay special attention to cleaning. Regardless of whether the boring tool is roughing or finishing, cleanliness must be paid attention to in all aspects of installing and assembling the boring tool. The assembly of the tool handle and the machine tool, the replacement of the blade, etc., must be wiped clean before installation or assembly. In the existing machining process, a workpiece needs to be roughed and finished, so the boring tool needs to be replaced during the second process. Due to the existing structure, the boring tool and the tool handle are in a one-to-one pairing relationship. If the boring tool needs to be replaced, the tool holder body needs to be replaced. The process is complicated, time-consuming and labor-intensive.
