Abstract
The utility model discloses a kind of milling cutters for high length-diameter ratio plate, cutter hub including knife handle and set on knife handle one end, cutter hub forms point of a knife far from one end of knife handle, cutter hub is equipped with several spiral chip spaces close to one end of the knife handle to the point of a knife from it, cutter hub surface forms several bar ditch back between adjacent helicla flute, the cutter hub surface is equipped with several reversed grooves along the hand of spiral contrary with the helicla flute and several bar ditch backs is correspondingly formed several chip pockets, and the ditch back between adjacent chip pocket wears into the tooth parallel with the chip space.The milling cutter for being used for high length-diameter ratio plate forms chip pocket by the groove intersected with chip space, and tooth is formed between adjacent chip pocket, sword is long to be increased, it is ensured that the rigidity and core thickness taper of tooth, to increase in leaf thickness, broken needle will not occur when boring high length-diameter ratio plate, while chip pocket assists chip removal, increase chip space, facilitate chip removal, meets the use demand of special plate.
Description
Technical field
The utility model relates to a kind of milling cutter more particularly to a kind of milling cutters for high length-diameter ratio plate.
Background technique
With the innovation of pcb board material, there are many special plates in processing PCB forming process in many producers, than
In order to improve efficiency, the thickness of substrate is increase accordingly in process for such as high TG plate, Teflon plate, thick copper sheet, and
Existing milling cutter is unable to satisfy the demand of these high length-diameter ratio plates, broken needle phenomenon usually occurs, influences the milling cutter service life.
Summary of the invention
In order to overcome drawbacks described above, the utility model provides a kind of milling cutter for high length-diameter ratio plate, meets high long
Diameter is than sheet fabrication demand.
The utility model is to solve technical solution used by its technical problem: a kind of for high length-diameter ratio plate
Milling cutter, the cutter hub including knife handle and set on knife handle one end, cutter hub form point of a knife far from one end of knife handle, and cutter hub is from it close to described
One end of knife handle to the point of a knife is equipped with several spiral chip spaces, and cutter hub surface is formed between adjacent helicla flute
Several bar ditch back, if the cutter hub surface will equipped with several reversed grooves along the hand of spiral contrary with the helicla flute
Dry bar ditch back is correspondingly formed several chip pockets, and the ditch back between adjacent chip pocket wears into the tooth parallel with the chip space.
As a further improvement of the utility model, the diameter of the cutter hub be 0.6~3.175mm, the knife handle it is straight
Diameter is 3.0~3.175mm.
The depth of the chip space is greater than the depth of the chip pocket as a further improvement of the utility model,.
The section of the chip pocket is rectangular as a further improvement of the utility model,.
The chip space is 6-8 item as a further improvement of the utility model,.
The beneficial effects of the utility model are: this, which is used for the milling cutter of high length-diameter ratio plate, passes through the groove that intersects with chip space
Chip pocket is formed, and forms tooth between adjacent chip pocket, sword is long to be increased, it is ensured that the rigidity and core thickness taper of tooth, from
And increase in leaf thickness, that is, broken needle will not occur when boring high length-diameter ratio plate, while chip pocket assists chip removal, increase and hold bits sky
Between, facilitate chip removal, meets the use demand of special plate.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model partial structural diagram；
Fig. 3 is point of a knife structural schematic diagram described in the utility model.
In conjunction with attached drawing, make the following instructions:
1 --- knife handle；2 --- cutter hub；
3 --- point of a knife；4 --- chip space；
5 --- ditch back；6 --- chip pocket；
7 --- reversed groove；8 --- tooth.
Specific embodiment
Below in conjunction with attached drawing, elaborate to a preferred embodiment of the utility model.But the guarantor of the utility model
Shield range is not limited to following embodiments, i.e., in every case with simple made by present utility model application the scope of the patents and description
Equivalent changes and modifications all still belong within the utility model patent covering scope.
Refering to fig. 1-3, a kind of milling cutter for high length-diameter ratio plate, including knife handle 1 and set on the cutter hub 2 of knife handle one end,
Cutter hub 2 forms point of a knife 3 far from one end of knife handle 1, and cutter hub 2 is equipped with several close to one end of the knife handle to the point of a knife from it
Spiral chip space 4,2 surface of cutter hub form several bar ditch back 5, cutter hub (2) surface between adjacent helicla flute
Along the hand of spiral contrary with the helicla flute be equipped with several reversed grooves 7 several bar ditch backs are correspondingly formed it is several
Chip pocket 6, the ditch back between adjacent chip pocket wear into the tooth 8 parallel with the chip space.
Wherein, the diameter of the cutter hub is 0.6~3.175mm, and the diameter of the knife handle is 3.0~3.175mm；The row
The depth for considering slot to be worth doing is greater than the depth of the chip pocket；The section of the chip pocket is rectangular；The chip space is 6-8 item.
The milling cutter for being used for high length-diameter ratio plate forms chip pocket by the groove intersected with chip space, and considers to be worth doing in adjacent appearance
Tooth is formed between slot, sword is long to be increased, it is ensured that the rigidity and core thickness taper of tooth are bored high to increase in leaf thickness
Broken needle will not occur when draw ratio plate, while chip pocket assists chip removal, increase chip space, facilitate chip removal, meet specific panel
The use demand of material.
