Heart angular region is 20 ° to 45 °,
Alternatively, ranging from 35 ° to 65 ° of the central angle corresponding to the second curve 11,
Alternatively, ranging from 45 ° to 55 ° of the central angle corresponding to third curve 9.
As shown in figure 3, when saw blade is treated and cut by cutting tool 6, the cutter head 7 of saw blade is cut, saw blade sawing
When, due to centrifugal force and the high-speed rotating effect of saw blade, movement locus of the cutting fluid on 1 surface of matrix flows to sawtooth side to tilt
To.The noise reductions such as traditional round hole, polygonal hole hole shape due to its hole shape, although cutting fluid can be stored, cannot have
Effect ground guiding cutting fluid flows to saw tooth region, it is impossible to improve the utilization rate of cutting fluid to the maximum extent.It is long and narrow in the present invention
For knife-edge hole shape tilt distribution on matrix, ' point of a knife ' portion is directed toward saw tooth region, will enter cutting process cutter head 8 and point of a knife
Distance is more than the distance of the cutter head just in cutting process, the fortune of the shape and arrangement with reference to cutting fluid on saw bit matrix
Emotionally condition, constantly by the cutting fluid pilot flow direction saw tooth region in run-in-hole shape, effect be similar to " water pipe " one by one and
When convey cutting fluid to saw tooth region, and then improve the cooling efficiency in sawtooth area.
During knife-edge noise reduction hole 2 is by cutting region, one side in the shape of hole where third curve 9 is always for drop
The chip in hole 2 of making an uproar has active force, and then chip is made quickly to leave joint-cutting with higher speed, reduces chip for sawtooth
Abrasion and influence.
