Abstract

The invention discloses a fine tuning finish-boring cutter, which includes a cutter bar body; a cutter loading core is inserted at the front end of the cutter bar body; the back part of the cutter bar body is provided with a set-bolt for locating the cutter loading core; the cutter bar body is also provided with a fine setting device interlocked with the cutter loading core and a displaying device displaying the adjustment volume of the fine setting device. The fine tuning finish-boring cutter rotates a fine setting handwheel, and adjusts the cutting volume according to a dial, which greatly shortens the adjusting time for cutting volume, and improves the work efficiency. Moreover, the fine tuning finish-boring cutter has high adjusting precision and can obtain ideal processing surface and precision.

Description

technical field [0001] The invention relates to a boring tool clamp for fine boring. Background technique [0002] The cutting depth of the hole wall is adjusted by the horizontal core boring machine. Usually, after each cut is completed, the set bolt of the cutter is loosened, and the pins of the dial indicator are touched against the side cutter surface of the cutter head, and the rear end of the cutter is tapped lightly or It often takes multiple times to adjust the cutting depth by directly judging the amount of knocking. Regardless of the gauge method or the direct judgment method, due to the tightening of the set bolts, the radius ratio of the tool tip will be changed, and it is difficult to achieve the required processing value, and the procedures are cumbersome and the efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fine-tuning fine boring tool, which can realize precise adjustment o...
