Abstract
The utility model discloses a round ultra-thin saw blade, and belongs to the technical field of cutting machining. The round ultra-thin saw blade comprises an annular metal substrate, the outer circumference of the metal substrate is provided with a plurality of sawtooth-shaped cutting tooth units connected in an end-to-end mode, each cutting tooth unit comprises cutting teeth and at least two tooth grooves, and the distances between adjacent cutting tooth tips of each cutting tooth unit are different. The round ultra-thin saw blade is provided with the plurality of the cutting tooth units, and the distances between adjacent cutting teeth in each cutting tooth unit are different, so that vibration frequencies of the cutting teeth are different, resonance of the ultra-thin saw blade in the cutting process is avoided, the vibration amplitude of the saw blade is reduced, machining precision of the ultra-thin saw blade is improved, and noise caused by vibration of the saw blade is lowered.
Description
Technical field
The utility model relates to a kind of circular ultrathin saw bit, belongs to Machining Technology for Cutting field.
Background technology
Because the blade of ultrathin saw bit is thinner, the cutting seam that it cuts out is also narrower, and stock utilization is high, and otch is smoothly without burr, and ultrathin saw bit is widely used in the workpiece that requirement on machining accuracy is high.The circular ultrathin saw bit of prior art comprises the metallic matrix of annular, is evenly distributed with zigzag cutting teeth on the outer circumference surface of metallic matrix, and the size of each cutting teeth, shape are all identical.Easily there is covibration in the ultrathin saw bit of this structure, during cutting, saw blade Oscillation Amplitude and noise increase in working angles, causes the machining accuracy of saw blade to reduce, and has a strong impact on the scope of application of ultrathin saw bit.
Summary of the invention
The purpose of this utility model is to provide a kind of circular ultrathin saw bit, to solve ultrathin saw bit saw blade Oscillation Amplitude and the large problem of noise when cutting of prior art.
For achieving the above object, the utility model adopts following technical scheme: a kind of circular ultrathin saw bit, the metallic matrix that comprises annular, on the excircle of described metallic matrix, be laid with end to end a plurality of serrated chip teeth unit, each cutting teeth unit comprises cutting teeth and at least two teeth groove, and the distance in each cutting teeth unit between adjacent two cutting teeth crowns is all not identical.
The quantity of described cutting teeth unit is 4 ~ 20 groups.
In described each cutting teeth unit, the difference of the distance in each cutting teeth crown and the metallic matrix center of circle is 0 ~ 10mm.
On described each cutting teeth, be coated with super-hard abrasive.
The utility model has a plurality of cutting teeths unit by ultrathin saw bit, distance in each cutting teeth unit between adjacent cutting teeth is different, this just makes the vibration frequency of each cutting teeth different, avoided ultrathin saw bit in working angles, to occur resonance, thereby reduced the Oscillation Amplitude of saw blade, the machining accuracy of ultrathin saw bit is improved, and saw blade generation of vibration noise also reduces simultaneously.
Further, the super-hard abrasive applying on cutting teeth improves the sharpness of cutting teeth, has greatly improved the cutting ability of saw blade.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
The structure of a kind of embodiment of the present utility model as shown in Figure 1, the circular ultrathin saw bit of the present embodiment comprises the metallic matrix 1 of annular, on the excircle of metallic matrix 1, be laid with end to end a plurality of zigzag cutting teeths unit 2, each cutting teeth unit comprises cutting teeth 3 and at least two teeth groove 4, on each cutting teeth 3, be coated with super-hard abrasive, the cutting teeth unit 2 of the present embodiment has eight, in each cutting teeth unit, all have four teeth groove, the distance in each cutting teeth unit between adjacent two cutting teeth crowns is all not identical.
Because the distance between cutting teeth adjacent in each cutting teeth unit in the present embodiment is different, this just makes the vibration frequency of each cutting teeth different, avoided ultrathin saw bit in working angles, to occur resonance, thereby reduced the Oscillation Amplitude of saw blade, so the ultrathin saw bit of the present embodiment have higher machining accuracy and less noise.
In other embodiment of the present utility model, in each cutting teeth unit, the height of each cutting teeth crown can be not identical, and in each cutting teeth unit, the difference of the distance in each cutting teeth crown and the metallic matrix center of circle can be the arbitrary value of 0 ~ 10mm.
In other embodiment of the present utility model, the quantity of cutting teeth unit can be set according to actual conditions, as long as the quantity of cutting teeth unit is greater than or equal to two; In each cutting teeth unit, the quantity of teeth groove also can be according to actual conditions setting, so long as be greater than or equal to two.
In other embodiment of the present utility model, can on cutting teeth, not apply super-hard abrasive, the cutting teeth that also can directly adopt superhard material to make.
Claims (4)
1. a circular ultrathin saw bit, the metallic matrix that comprises annular, it is characterized in that: on the excircle of described metallic matrix, be laid with end to end a plurality of serrated chip teeth unit, each cutting teeth unit comprises cutting teeth and at least two teeth groove, and the distance in each cutting teeth unit between adjacent two cutting teeth crowns is all not identical.
