The cutter head width of above-mentioned operate portions and the ratio of outside diameter are more little, and the cannelure width diameter that then cuts out is than more little, and its cutting output is corresponding also more little, and power consumption is also corresponding few more, but this ratio can not select too for a short time, otherwise cutter can not be born machining.According to calculating and experiment, the percentage of this ratio is that 5-10% is advisable.
The quantity of above-mentioned cutter head is many more, and then cutting output and the cutting force shared of each cutter head is more little, and the barrel thickness of operate portions can design lessly.But,,, operate portions intensity and rigidity all can be descended much so it is big more to open the helicla flute density of system in the barrel periphery of working because helicla flute and cutter head that chip removal is used match if cutter head quantity is too many.According to calculating and experiment, the quantity of cutter head is that the 5-7% round numbers of outside diameter is advisable.
The main sword of above-mentioned each cutter head is again simultaneously branch bits swords, and the smear metal that can will equal the cutter head width is divided into the annulus suitable with the cutter head number, and selecting for use suitable anterior angle can make the annular chip fracture again is chip.When the sword length of each main sword equaled the width of cutter head, the inside and outside circular edges of the annular track of each main sword linked to each other, and under slight cutting vibration, the gap can not occur between the circular edges of each annular track, until the coincidence that has small part, was unlikely to occur leaking and cut; If the long sum of the sword of each main sword is slightly larger than the width of cutter head, the annular track that then can be designed to each main sword slightly overlaps on circular edges, cuts to guarantee not leak.
The utlity model has following advantage and effect.
1, adopt multitool head and thin-walled operate portions, can reduce cutting output greatly, reduce power consumption, the material that reduces work piece expends.Particularly can the smaller cannelure of working groove wide diameter.
2, adopt the helical surface of the cutter head and the hard metal of hard metal tip, can not only improve cutter life, and can save expensive hard metal in a large number.Cutter head is inlayed along spiral, is more conducive to chip removal.
3, each cutter head master sword also is branch bits swords, has cutting concurrently and divides the bits function, and chip breaking is good, is realized that unimpededly chip removal provides assurance, thereby the assurance cutting is reliably carried out.Main sword is vertical with tool axis, the annular groove bottom surface flatness height that cuts out.
Below, the utility model is further described with embodiment and comparative examples accompanying drawing again.
