Abstract
The utility model aims to provide a helical end mill capable of reducing or eliminating harmonic vibration produced during the processing, so as to improve the processing quality and the processing efficiency. The helical end mill provided by the utility model comprises a handle part and an edge part, wherein, a plurality of parabola-shaped side edges are arranged at the edge part in the axial direction of the edge part; and the key lies in that the helical angles of the plurality of side edges are different from each other. In the processing process, the plurality of side edges with the helical angles different from each other can produce cutting movements of different phases, thereby preventing the occurrence of resonance, reducing or eliminating the vibration during the processing, enabling the abrasion of the mill to be reduced and improving the surface finish degrees of work pieces. The helical end mill provided by the utility has the advantages that the harmonic vibration produced during the processing is reduced or eliminated by arranging the unique helical angles and unique intervals of the side edges, so that high-speed processing or high-efficiency cutting can be conducted, the surface quality of the work pieces to be processed is steady and reliable, and the service life of the mill is prolonged by 28 percent. Therefore, the processing cost is lowered.
Description
Technical field
The utility model belongs to cutter manufacturing technology field, specially refers to a kind of helical end mills.
Background technology
Drill bit with an important component part in the cutter, is mainly used in the roughing in hole as machining.Along with the development of mechanical industry, the user is to having proposed requirements at the higher level delivery date of the crudy of product, process reliability, working (machining) efficiency, cutter etc.The helical angle of conventional helical slotting cutter is evenly distributed, and therefore has drawback: 1, add trade union and produce continual harmonic vibration, cause the piece surface crudy to reduce, cause workpiece to reprocess, even workpiece is scrapped; 2, can not adopt roughing feed cutting, machining efficient low.
The utility model content
The purpose of the utility model is to propose a kind of helical end mills, can reduce or eliminate to add the harmonic vibration that produce man-hour, thereby improve crudy and working (machining) efficiency.
The helical end mills of the utility model comprises shank and blade, and said blade is along himself being axially arranged with many parabola shaped side edges, and key is that the helical angle of said many side edges has nothing in common with each other.
In process, many side edges that helical angle has nothing in common with each other can produce the cutting movement of an out of phase, thereby stop the generation of resonance, thereby reduce or eliminated the vibration in the processing, the wearing and tearing of cutter are reduced, and improved workpiece surface finish.
Further, the spacing of adjacent side edge has nothing in common with each other in said many side edges, has changed the fixed frequency of cutter tooth incision workpiece, becomes a different set of frequency values, thereby has further reduced the vibration in the processing.
Further, the surface of this helical end mills is provided with the X-CEED coating.The X-CEED coating is a kind of of TiAlN coating; Higher hardness is not only arranged, also have mar proof preferably, can make cutter have excellent red hardness, non-oxidizability; Even under abominable processing conditions; Its film and matrix still have good binding intensity, can process the heat-treated steel below HRC68 °, and unmanageable stainless steel, titanium alloy, nickel-molybdenum alloy material.
The helical end mills of the utility model is through being provided with the helical angle and the spacing of unique side edge; Reduce or eliminated to add the harmonic vibration that produce man-hour; Therefore can carry out the cutting of High-speed machining or high efficiency; The surface quality of processing work is reliable and stable, and cutter life prolongs 28%, thereby has reduced processing cost.

The specific embodiment
Contrast accompanying drawing below; Through description, the effect of the mutual alignment between the shape of the specific embodiment of the utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are done further to specify to embodiment.
Embodiment 1:
Like Fig. 1, shown in 2; Present embodiment is four groove helical end millses; Its surface is provided with the X-CEED coating, and four groove helical end millses comprise shank 1 and blade 2, and blade 2 is along himself being axially arranged with many parabola shaped side edges 3; The helical angle of many side edges 3 has nothing in common with each other, and the spacing of adjacent side edge has nothing in common with each other in many side edges 3.
Specifically:
As shown in Figure 1, the helical angle R1 of the side edge 3 that has is 41 °, and the helical angle R2 of the side edge 3 that has is 38 °, and by that analogy, the helical angle of four side edges 3 has nothing in common with each other, and the difference between each helical angle is 3 degree.
As shown in Figure 2, represent spacing L1, L2, L3, the L4 of adjacent side edge with angle, concrete numerical value is following: L1=84 °, L2=87 °, L3=93 °, L4=96 °, promptly the spacing of adjacent side edge is all inequality, and finally adds up and equal 360 °.
In process; The helical angle of many side edges has nothing in common with each other, and the spacing of adjacent side edge is all inequality, can produce the cutting movement of an out of phase; Thereby stop the generation of resonance; Thereby reduce or eliminated the vibration in the processing, the wearing and tearing of cutter are reduced, and improved workpiece surface finish.
The helical end mills of present embodiment utilizes numerical control five-axle interlock grinding machine, independently writes knives routine and processes, and its matrix material adopts carbide alloy.
Claims (3)
1. a helical end mills comprises shank and blade, and said blade is characterized in that along himself being axially arranged with many parabola shaped side edges the helical angle of said many side edges has nothing in common with each other.
2. helical end mills according to claim 1 is characterized in that the spacing of adjacent side edge in said many side edges has nothing in common with each other.
3. helical end mills according to claim 1 and 2 is characterized in that the surface of this helical end mills is provided with the X-CEED coating.
