Disposable integrated coarse-fine boring tool

Abstract

The invention discloses a disposable integrated coarse-fine boring tool comprising a tool handle and a tool bit integrated with the tool handle. A fine boring blade is detachably fixed on the front end of the tool bit; a coarse boring tool bit is detachably fixed on the middle-rear part of the tool bit; the points of both the fine boring blade and the coarse boring tool bit are respectively arranged on two sides of the center of the tool bit; and a chip breaking groove is arranged on the coarse boring tool bit. A coarse boring tool and a fine boring tool are integrated into a whole, thus the requirement of one tool for coarse boring and fine boring is met, and the problems of many processing substeps and low efficiency existing in the traditional processing method are solved, and more importantly, the requirement of high-precision holes and the flexible production requirement of mass parts for processing efficiency and IE engineering are met.

Description

Rough and fine integrated discarded boring tool technical field The invention relates to the field of mechanical processing, in particular to a rough-finish integrated discarding boring tool for continuous and high-efficiency rough-finish boring processing. Background technique For a long time, continuous and efficient mechanical roughing and finishing has been the processing concept pursued in the field of metal processing. For the boring processing with large quantities and high-precision hole requirements, there are two common processing methods: one is to use the combination of rough and fine boring, but the rough and fine boring tools are divided, that is, two tools are used for processing , so that continuity and efficiency cannot be achieved. Especially under the condition that the space conditions of the equipment are limited and several cutting tools cannot be installed at the same time, this traditional method cannot be used; It is used for finishing turning to...

AI Technical Summary

Problems solved by technology

This traditional processing method meets the high-precision hole processing requirements of stainless steel and non-ferrous metal parts commonly used in the auto parts and precision instrumentation industries. Its disadvantages are that there are many procedures, long processing time, and manual intervention , the processing is discontinuous and the production efficiency is relatively low, and the advanced nature of flexible processing equipment cannot be brought into play
