Abstract
The utility model relates to a cutter, in particular to a numerical control inner hole boring cutter of a numerical control lathe, which comprises a main cutter blade, a major-minor cutter blade, a cutter arbor and a cutter body; the front end of the cutter arbor is provided with the main cutter blade and the major-minor cutter blade; the rear end of the cutter arbor is provided with the cutter body; the included angle Alpha formed by the major-minor cutter blade and a horizontal line is 5 to 10 degrees, a transition blade N between the main cutter blade and the major-minor cutter blade is 2 to 3mm, a cutter head inclined surface K formed by the main cutter blade and the major-minor cutter blade is 20 to 25mm, and the circular arc radius R of a cutter tip circular arc-shaped surface formed by the main cutter blade and the major-minor cutter blade is 0.3 to 0.5mm. Q is the thickness of the cutter body and is 6mm*6mm*40mm. The included angle H formed by the main cutter blade and the horizontal line is 30 to 40 degrees. The numerical control inner hole boring cutter has the advantages of simple structure, low cost, and convenience in installation, detachment and operation.
Description
Technical field: the utility model relates to cutter, is specially a kind of numerical control endoporus boring cutter of numerically controlled lathe.
Background technology: existing numerical control Boring cutter, because cutter hub is generous, point of a knife does not arrive the workpiece center of circle, because the cutter hub relation: processing of minor diameter blind hole or the processing of endoporus circular arc, it is restricted that CNC turning tool is used.
Summary of the invention: the purpose of this utility model be to provide a kind of simple in structure, with low cost, by dress, disassembling section numerical control endoporus boring cutter easily.The purpose of this utility model is achieved in that it comprises major cutting edge, major-minor blade, knife bar, cutter hub. the knife bar front end is provided with major cutting edge, major-minor blade, knife bar rear end and is provided with cutter hub, major-minor blade and horizontal angle α are 5 °-10 °, transitional edges N between major cutting edge and the major-minor blade is 2mm～3mm, the cutter head inclined-plane K that major cutting edge and major-minor blade constitute is 20mm-25mm, and the arc radius R of the tool arc face that major cutting edge and major-minor blade constitute is 0.3mm-0.5mm.Q is that the thickness of cutter hub is 6mm * 6mm * 40mm.Major cutting edge and horizontal angle H are 30 °-40 °.The utility model has the advantages that simple in structure, with low cost, convenient by dress, disassembling section.
Description of drawings: Fig. 1 is the utility model structural principle schematic diagram; The 2nd, the utility model structural principle major cutting edge and major-minor blade schematic diagram; Fig. 3 is the utility model structural principle M enlarged diagram.
The specific embodiment: it comprises major cutting edge 1, major-minor blade 2, knife bar 3, cutter hub 4.Knife bar 3 front ends are provided with major cutting edge 1, major-minor blade 2, knife bar 3 rear ends and are provided with cutter hub 4, major-minor blade 2 is 5 °-10 ° with horizontal angle α, transitional edges N between major cutting edge 1 and the major-minor blade 2 is 2mm～3mm, major cutting edge 1 is 20mm-25mm with the cutter head inclined-plane K that major-minor blade 2 constitutes, and major cutting edge 1 is 0.3mm-0.5mm with the arc radius R of the tool arc face that major-minor blade 2 constitutes.Q is that the thickness of cutter hub is 6mm * 6mm * 40mm.Major cutting edge 1 is 30 °-40 ° with horizontal angle H.The utility model grinds with the high-speed steelknife piece and forms.The length of knife bar can extend according to the degree of depth of workpiece internal control.The intensity of lathe tool can satisfy, and the circular arc processing effect is the most desirable in interior blind hole processing of part to be processed minor diameter and the minor diameter.
