This utility model is related to a kind of flat spot facing cutter of turnery processing, including knife bar and cutter hub.Knife bar is square bar body, and cutter hub is that the flat body lathe tool of three face swords is fixedly mounted in the oblique square hole of knife bar.Before the nose part of cutter hub, cutting edge arranged on left and right sides side is left cutting edge and right cutting edge, and is provided with arcuate groove between the two.Front cutting edge is provided with initial incision anterior angle, and initial incision anterior angle is γ angles with the angle of front cutting angle of cutting edge, and initial incision anterior angle is connected with the arcuate groove between left cutting edge, right cutting edge.This utility model simple structure, cutter hub intensity are high;Big flat-bottom hole highly-efficient processing is capable of achieving, the design requirements such as aperture, roughness are effectively ensured.

Description

A kind of flat spot facing cutter of turnery processing
Technical field
This utility model is related to cutting-tool engineering field, specifically a kind of turning large disc type flat-bottom hole cutter.
Background technology
We can run into one larger-diameter flat-bottom hole of processing on workpiece in cutting process, usually, generally Processing method be first in one hole of flat-bottom hole center drilling that the workpiece is to be processed, then progressively from center to Outer layer or car boring carry out the flat hole machined of major diameter.In the case that this method is little for processing aperture, its working (machining) efficiency is also Can receive, but when the flat-bottom hole of larger aperture is processed, this traditional processing method efficiency seems very low, and cutter is firm The poor, chip removal of property is difficult.
Utility model content
For above-mentioned current condition, this utility model provides a kind of turning large disc type flat-bottom hole cutter.
The purpose of this utility model content is achieved by the following technical programs:
A kind of flat spot facing cutter of turnery processing, including knife bar 1 and cutter hub 2.Knife bar 1 is set for square bar body, and the leading portion of knife bar 1 There is oblique square hole.Cutter hub 2 is that the flat body lathe tool of three face swords is arranged in the oblique square hole of knife bar 1, and is bolted on knife bar 1 On.
The anterior angle of 2 nose part of cutter hub is 2 °, and relief angle α is 4 ~ 6 °.Before nose part, the arranged on left and right sides side of cutting edge 5 is left cut Cut sword 6 and right cutting edge 7, and relief angle α 1 of left cutting edge 6 be 6 ~ 9 °, relief angle α 2 of right cutting edge 7 is 3 ~ 5 °, wherein α 1 with plus The size of work diameter of bore is relevant, and diameter of bore is less, and α 1 is bigger.
Arcuate groove is provided between the right cutting edge 7 of the left cutting edge 6 and cutter hub 2 of cutter hub 2.The anterior angle of front cutting edge 5 is first Beginning entrance angle γ, initial incision anterior angle γ angle is between 8 ~ 12 °, and the back segment of initial entrance angle and left cutting edge 6, right cutting edge 7 Arcuate groove be in progressive round and smooth connection.
This utility model Advantageous Effects are as follows:
1. cutter structure is simple, and cutter hub intensity is high;
2. big flat-bottom hole highly-efficient processing is capable of achieving, the design requirements such as aperture, roughness are effectively ensured;
3. there is low cost of manufacture, the features such as safe and reliable.

Specific embodiment
Below in conjunction with the accompanying drawings, by embodiment, the utility model is further described.
Embodiment one:
Referring to Fig. 1.A kind of flat spot facing cutter of turnery processing, including knife bar 1 and cutter hub 2.
Referring to Fig. 2.Knife bar 1 is square bar body, and the leading portion of knife bar 1 is provided with oblique square hole.
Referring to Fig. 3.Cutter hub 2 is that the flat body lathe tool of three face swords is arranged in the oblique square hole of knife bar 1, and is bolted on On knife bar 1.2 total length l of cutter hub is 65mm, including flute portion l2With shank l3, shank l3Length be 45 ~ 55mm;Flute portion l3, Including working portion and inoperative part, length is 10 ~ 20mm.
Referring to Fig. 4, Fig. 5, Fig. 6.The anterior angle of 2 nose part of the cutter hub is 2 °, and relief angle α is 4 ~ 6 °.Cutting edge 5 before nose part Arranged on left and right sides side be left cutting edge 6 and right cutting edge 7, and relief angle α 1 of left cutting edge 6 is 6 ~ 9 °, the relief angle of right cutting edge 7 α 2 is 3 ~ 5 °.
Arcuate groove is provided between the left cutting edge 6 and right cutting edge 7 of cutter hub 2.
The anterior angle of front cutting edge 5 is initial entrance angle γ, and initial incision anterior angle γ angle is 8 ~ 12 °, and initial entrance angle Arcuate groove between back segment and left cutting edge 6, right cutting edge 7 is in progressive round and smooth connection.
Embodiment two:
Utility model works principle:
Referring to Fig. 7, Fig. 8, Fig. 9.The front cutting edge 5 of cutter hub 2 is making length feed cutting with machine cut main axis parallel, together When cutter hub 2 front cutting edge 5 originate in part to be processed internal diameter make traverse feed cutting, in working angles cut Integrated Chip enter Arcuate groove of the initial incision anterior angle between cutting edge 6 and right cutting edge 7 is discharged, and successively feeding completes the full mistake of the processing of flat-bottom hole Journey, wherein α 1 are relevant with the size of processing diameter of bore, and diameter of bore is less, and α 1 is bigger.
In addition, some flat-bottom hole roots need fillet, will can be milled into closing at the left point of a knife 3 of the cutter, 4 liang of right point of a knife Suitable rounded shapes.Such cutter is the variant of this dedicated tool.
