Abstract
The invention aims to provide a spiral end milling cutter. The spiral end milling cutter can reduce or eliminate harmonic vibration generated during processing so as to improve processing quality and processing efficiency. The spiral end milling cutter comprises a handle part and an edge part, wherein the edge part is provided with a plurality of parabolic side edges along the axial direction of the edge part; and the key point is that the spiral angles of the plurality of parabolic side edges are different from one another. In the processing process, the plurality of parabolic side edges with different spiral angles can generate cutting motion with different phase positions, so that resonance is prevented from being generated, vibration during processing is reduced or eliminated, abrasion of the cutter is reduced, and surface finishment of workpieces is improved. The spiral end milling cutter is provided with unique spiral angles and spacing of the side edges, so the harmonic vibration generated during processing is reduced or eliminated, high-speed processing or high-efficiency cutting can be performed, the surface quality of the processed workpieces is stable and reliable, the service life of the cutter is prolonged by 28 percent, and processing cost is reduced.
Description
Technical field
The invention belongs to cutter manufacturing technology field, specially refer to a kind of helical end mills.
Background technology
Drill bit is mainly used in the roughing in hole as an important component part in the machining usefulness cutter.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 following shortcoming: 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.
Summary of the invention
The objective of the invention 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.
Helical end mills of the present invention comprises shank and blade, and described blade is along himself being axially arranged with many parabola shaped side edges, and key is that the helical angle of described 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 described 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 has 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.
Helical end mills of the present invention is by 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, cutter life prolongs 28%, thereby has reduced processing cost.
Description of drawings
Fig. 1 is the structural representation of helical end mills of the present invention.
Fig. 2 is the head construction schematic diagram of helical end mills of the present invention.
Among the figure: the 1---shank; The 2---blade; The 3---side edge; R1, R2---helical angle; L1, L2, L3, L4---tooth pitch.
The specific embodiment
Contrast accompanying drawing below, by description, the effect of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are described in further detail embodiment.
Embodiment 1:
As shown in Figure 1, 2, present embodiment is four groove helical end millses, its surface is provided with the X-CEED coating, four groove helical end millses comprise shank 1 and blade 2, 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 as follows: 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 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 described blade is characterized in that along himself being axially arranged with many parabola shaped side edges the helical angle of described 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 described 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.
