Structure is simple, esy to use, safe and reliable.
Realization the technical scheme is that a kind of processing band boss internal circular-grooves boring cutter, including cutter hub and blade, institute
Stating cutter hub front end radial direction has four square holes；It is characterized in that: described blade is in l shape, and the long side of its blade loads cubic in the hole, and with pressing
Tight screw is fixed, and its cutting edge is in boring cutter foremost in blade minor face away from the end on the long side of blade.
There is chip-breaker described blade short side.
The cross section of described chip-breaker is circular arc, and its arc radius is r, and groove depth is h, and groove width is l.
Tangent line at cutting edge for the described chip-breaker cross section circular arc is 12 ° with the angle of blade left surface.
The blade minor face end plane that described cutting edge is located is blade minor face front end inclined-plane.
Described blade minor face front end inclined-plane is 8 ° with the angle of blade minor face vertical plane.
It is inclined-plane outside blade minor face outside described blade minor face.
Outside described blade minor face, inclined-plane and the angle of blade left surface are 73 °.
The cutting edge place end of described blade slightly upwarps, and makes inclined-plane outside blade minor face, the reticule of blade left surface
It is less than 90 ° with the angle of cutting edge.
Outside described blade minor face, the angle on inclined-plane, the reticule of blade left surface and cutting edge is 88 °
The invention has the beneficial effects as follows:
1st, cutter cutter hub energy life-time service, blade can sharpen Posterior circle and use, and reduce cutter manufacture cycle and manufacturing cost；
2nd, versatility is stronger, for the part of different sizes, only passes through to adjust blade position, improves the utilization of cutter
Rate；
3rd, after changing or sharpen cutter head, same size annular groove can be by knife ring fast rough, the low size of dimensional requirement
Locating and machining requirement can be met, directly process；
4th, achieve and disposably complete annular groove back chipping, good ensure that product requirement, it is to avoid tool changing, tool-setting error；
5th, present configuration is simple, esy to use, safe and reliable.
6th, the present invention successfully realizes the clean-up machining with boss internal circular-grooves, and size and roughness have obtained good guarantor
Card；Lamps structure is reasonable in design simultaneously, easy to manufacture, greatly improves part quality, reduces the manufacturing cost of product.

Specific embodiment
As shown in Fig. 1 is to 5, a kind of processing band boss internal circular-grooves boring cutter, including cutter hub 1 and blade 2, described cutter hub 1
Front end radial direction has four square holes 3；Described blade 2 is in l shape, and the long side of its blade 7 loads in four square holes 3, and fixing with housing screw 6,
Its cutting edge 4 is in boring cutter foremost in blade minor face 8 away from the end on the long side of blade 7.Have in described blade minor face 7 side
Chip-breaker 5, the cross section of this chip-breaker 5 is circular arc, and its arc radius is r, and groove depth is h, and groove width is l；Wherein, groove width l, groove
The concrete size of deep h and arc radius r determines according to tool dimension and Dimension Measurement；Described chip-breaker 5 cross section circular arc
Tangent line at cutting edge 4 is 12 ° with the angle of blade left surface 14.The blade minor face end plane that described cutting edge 4 is located
For blade minor face front end inclined-plane 10；This blade minor face front end inclined-plane 10 and the angle of blade minor face vertical plane are 8 °.Described knife
