Problems solved by technology

Set the diameter of the dial to Φ20, the circumference is approximately equal to 63, and the engraved line is set to 60 grids, then the diameter is adjusted to Φ0.06 per revolution, and the corresponding pitch is 0.03. Obviously, it is very difficult to process such a small pitch, even if it can be guaranteed Requirements, the rigidity of the nut and the screw is also very weak, and it is easy to be damaged by the cutting force in actual processing.
Therefore, the service life of existing high-precision boring tool is all relatively short

Abstract

The invention provides a slant micro-feeding metal cutting tool, relates to the technical field of metal cutting machining and aims at solving the technical problem of prolonging the service life of a high-precision boring cutter. The cutting tool comprises a tool handle and a tool apron; a slider and a fine adjusting screw are arranged on the tool handle; the slider is mounted on the upper end of the tool handle clamping groove matching and sliding manners, and the sliding axis of the slider is perpendicular to the axis of the tool handle; a fine adjusting groove is formed in the bottom surface of the slider; the fine adjusting groove is a straight groove perpendicular to the axis of the tool handle and inclined to the sliding axis of the slider; the tool apron is mounted on the slider; the fine adjusting screw is rotatably mounted on the tool handle; the rotating axis of the fine adjusting screw is perpendicular to the axis of the handle and perpendicular to the sliding axis of the slider; a fine adjusting nut matched with the threads of the fine adjusting screw sleeves the fine adjusting screw; the top end of the fine adjusting nut is embedded into the fine adjusting groove in the bottom surface of the slider in a clearance fit manner. The cutting tool is high in adjustment precision and long in service life.

Description

technical field [0001] The invention relates to metal cutting processing technology, in particular to the technology of a metal cutting tool with inclined surface micro-feed. Background technique [0002] In the field of metal processing, high-precision holes on non-rotating parts are usually solved by machining center boring. A high-precision machining center can solve the requirements of the position accuracy of the hole system and the roundness accuracy of the hole, but the dimensional accuracy of the hole itself depends on the adjustment accuracy and reliability of the boring tool. [0003] Conventional boring tools use a single screw to adjust the position of the cutter head. In order to obtain a small adjustment, it is often necessary to sacrifice the rigidity of the screw and nut. For example, to engrave the engraved line with an accuracy of Φ0.001 for each grid, for the convenience of operation, the adjacent engraved line is given about 1mm in advance. Set the diam...
