Embodiment Construction

[0012] Example, by figure 1 , figure 2 , image 3 Shown:

[0013] The inner hole slotting cutter of this embodiment has an integrally formed structure, which has a cylindrical handle 1, and a holding plane 2 is milled out on the handle 1, so that the cutter can be more stably held on the tool holder; The front end is milled with an arc surface 3, which intersects with the extension surface 4 of the outer arc of the handle to form a transitional shank with a cross-sectional shape that is approximately oval (cat-eye-shaped), and the transitional shank is thinner than the shank , during processing, the tool rod goes deep into the hole, and the gap between it and the hole wall is relatively large, so that the cutting debris can be discharged smoothly; the front end of the transition tool rod is milled with a section plane 5 parallel to the axis of the tool bar, and the section plane It and the inclined section 6 of the transition tool bar form the chip removal groove of the fl...

Abstract

The invention relates to an inner bore grooving cutter which is an integrally formed structure. The inner bore grooving cutter comprises a cylindrical cutter handle, wherein a clamping plane is arranged on the cutter handle; an arc surface is milled on the front end of the cutter handle; the arc surface is crossed with an extending surface of a circular arc outside the cutter handle to form a transitional cutter bar with a similar oval sectional form; a cutting plane parallel to an axis of the cutter bar is milled on the front end of the transitional cutter bar; the cutting plane and an inclined section of the transitional cutter bar are enclosed to form a chip groove of the grooving cutter; a cutting edge is arranged on the top end of the transitional cutter bar; the front surface of the cutting edge is arranged on the cutting plane of the transitional cutter bar. The inner bore grooving cutter occupies little machining space and removes chips smoothly, and can machine inner threads with various thread pitches from 0.2mm to 10 mm or more; a relief angle of the threads is modified according to a spiral lifting angle for machining the threads, so that the cutter is ensured to be cut smoothly.

Description

technical field [0001] The invention relates to an internal thread cutter, in particular to an internal hole slotting cutter. Background technique [0002] Common tools used to process the inner ring groove of nuts are solid carbide thread milling cutters and rack-blade thread milling cutters, which have 5-7 tooth tip threads and can complete the threads at one time. The general processing flow of the multi-tooth thread milling cutter is that the cutting edge of the thread milling cutter is covered with thread processing teeth, through the three-axis linkage of the CNC machine tool, the forming thread milling cutter is used to perform helical interpolation to form threads, and the tool processes a circle along the helical line The thread processing can be completed, and it can also be rotated for several weeks to reach the required depth of the thread. The disadvantage is that the multi-tooth thread milling cutter takes up a lot of processing space, and the chip removal is ...
