Description
Technical field
The utility model is related to process tool and in particular to electronic circuit board dedicated tool.
Background technology
Tool in Cutting industry make rapid progress, the application of cutter is more and more extensive, may not only be applied to wood cutting, gold
Belong to cutting, new-type cutter also begins to be applied to cut some special nonmetallic materials.Materials processing due to electronic circuit board
Have high demands, lead to the cutter being never suitable for be used for processing circuit board.Existing circuit board process tool cannot meet now
Circuit board cuts the processing request of industry, low production efficiency, and cost of manufacture is high, and cutter life is low, machining accuracy low
The problem of series is badly in need of solving, and to circuit board, this special rapidoprint is felt simply helpless for existing enterprise；Above-mentioned in order to solve
The working (machining) efficiency of the presence of circuit board is low, and production cost is high, and the machining accuracy of circuit board is low, the cutting speed of circuit board dedicated tool
Degree is slow, and the chip space of cutter is little, and chip removal ability is poor, the problems such as cutting-tool's used life is short, therefore researches and develops a kind of brand-new electricity
Road plate dedicated tool has certain meaning.
Utility model content
Cutting speed is high in order to provide one kind to have for the purpose of this utility model, and machining accuracy is high, and chip space is big, chip removal
Ability is strong, the perfect heat-dissipating of cutter, cutter uniform force, the electronic circuit board dedicated tool of the life-span length of cutter.
For realizing the purpose of this utility model, the utility model adopts the following technical scheme that：A kind of electronic circuit board is special
Cutter includes handle of a knife, and described handle of a knife is provided with neck, and described neck is provided with cutter hub, wherein：Described cutter hub includes apex point, cutting
Part, chip removal helicla flute, described apex point is connected with described cutting tip, and cutting tip is provided with land, and described land connects row
Bits helicla flute, described apex point is provided with chisel edge.
Preferably, described cutter hub includes cutting edge, and described margin width is 0.065 to 0.075 multiple of cutting edge diameter length.
Preferably, the formation chisel edge angle of described chisel edge and described cutter hub horizontal plane, the described chisel edge angle number of degrees arrive at 45 °
Between 55 °.
Preferably, described chisel edge length is 0.3mm 0.5mm.
Preferably, described apex point includes three angles, and the angle of described angle is 118 °.
The beneficial effects of the utility model：Cutting tip is provided with land, and during use, land is formed with the gap of hole wall,
Be conducive to the injection of coolant；Margin width is 0.065 to 0.075 multiple of cutting edge diameter length, the processing to cutter for the land
When play certain guide effect, land is too wide, friction produce heat can increase；Land is too small, stablizing during tool sharpening
Property is bad, and cutter easily swings, using such width land so that cutter good stability and frictional force in process
Little, cutting speed is high, and machining accuracy is high, long service life；Land connects chip removal helicla flute, and chip space is big, good heat dissipation effect；
Chisel edge and the formation chisel edge angle of described cutter hub horizontal plane, between 45 ° to 55 °, chisel edge length is the described chisel edge angle number of degrees
0.3mm 0.5mm, chisel edge plays a part centering, improves the machining accuracy of cutter；Apex point includes three angles, described angle
Angle be 118 °, improve the machining accuracy of cutter and cutting speed, using the electronic circuit board dedicated tool of said structure,
Make cutter hub uniform force in process, improve cutting-tool's used life.
Brief description
Fig. 1 is front view of the present utility model；
Fig. 2 is right view of the present utility model；
Fig. 3 is right sectional view of the present utility model.
1 is apex point, and 2 is land, and 3 is chip portion, and 4 is chip removal helicla flute, and 5 is neck, and 6 is handle of a knife, and 7 is cutter hub, and 8 are
Chisel edge, 9 is cutting edge diameter, and α is chisel edge angle, and β is angle.
Specific embodiment
Further illustrate below in conjunction with the accompanying drawings：
As illustrated in the accompanying drawings from 1 to 3：The utility model includes handle of a knife, and described handle of a knife is provided with neck, and described neck is provided with knife
Body, wherein：Described cutter hub includes apex point, cutting tip, chip removal helicla flute, and described apex point is connected with described cutting tip, cutting
Partly it is provided with land, described land connects chip removal helicla flute, described apex point is provided with chisel edge；Described cutter hub includes cutting edge, institute
State 0.065 to 0.075 multiple that margin width is cutting edge diameter length；Described chisel edge and the formation chisel edge of described cutter hub horizontal plane
Oblique angle, the described chisel edge angle number of degrees are between 45 ° to 55 °；Described chisel edge length is 0.3mm 0.5mm.Preferably, described apex point
Including three angles, the angle of described angle is 118 °.
When margin width is 0.065 times or 0.075 times of cutting edge diameter length, cutting performance is optimal.
When the chisel edge angle number of degrees are 45 ° or 55 °, cutting performance is optimal.
When chisel edge length is 0.03mm or 0.05mm, cutting performance is optimal.
The purpose of this utility model, feature and advantage will be further described in conjunction with the embodiments referring to the drawings.By reality
