Please refer to Fig. 1-3, in the utility model embodiment, a kind of polycrystalline diamond composite step multiple cut polishing blade
Tool, including knife handle 1, the structure of the knife handle 1 can have following four: the short cone of staight shank, Morse taper shank, 7:24 taper shank, HSK1:10 is empty
Heart handle, the knife handle 1 select K10~K20 hard alloy or structural alloy steel to be processed into, and the hardness after heat treatment is 45~
48HRC, the shank of knife handle 1 are staight shank, and the diameter D precision of knife handle 1 is h6 or h5 grades.
The middle part of the knife handle 1 offers at least two first insert grooves 3, and the end of knife handle 1 offers at least two
Two insert grooves 4 are equipped with the first composite polycrystal-diamond 2 on first insert groove 3, and it is poly- that second is equipped on the second insert groove 4
Diamond composite sheet 5, the average crystalline substance of 5 diamond layer of the first composite polycrystal-diamond 2 and the second composite polycrystal-diamond
Composite polycrystal-diamond, the insert groove of knife handle 1 is welded to the method for vacuum welding or high-frequency welding by grain diameter≤2 μm
In.
Embodiment 2
Please refer to Fig. 1-3, the present embodiment difference from example 1 is that:
In the present embodiment, first insert groove 3 and the second insert groove 4 on knife handle 1 in being circumferentially uniformly arranged.
In the present embodiment, by cutting polishing acrylic material design, the circumferential cutting edge of the second composite polycrystal-diamond 5
It is made into back taper 1:100, axial rake is 5~8 °；The chamfering blades axial rake of first composite polycrystal-diamond 2 is 5~10 °,
Orthogonal cross-section anterior angle is 0~6 °, and the first relief angle is 3~8 °, and the second relief angle is 12~18 °；Second composite polycrystal-diamond 5
End clearance angle is 6~8 °, and geometric parameters are waited in drift angle 5~15 ', and blade must be sharp, at least detects blade under 200 power microscopes
Without jaggedness defect, front and rear knife face must bright and clean Ra≤0.05 μm.
The flank (relief angle) for completing end sword, circumference blade and chamfered cutting edge on the diamond cutter knife sharpener of numerical control is ground
Mill；Whole cutting blades are to bounce≤3 μm on the basis of shank outer circle.
The approximate helical line of circumference blade is automatically generated by artificial fitting or lathe software on numerical control diamond knife sharpener
Cutting edge, so that the cutting of circumference blade is more stable, cutting polishing effect is more preferable.Cutting edge length is L3, and cutting edge diameter is d, such as
Rotation angle of the fruit when automatically generating helix on Britain's RG9 lathe is the angle θ, then this approximate helical blade can be calculated
Helixangleβ, calculation method is as follows:
β=tg-1(π d/P)=tg-1(θπd/360°L3)；
In formula: θ is rotation angle when numerical control knife sharpener sharpens, unit: ° (degree)；D be circumferential cutting edge diameter, unit:
mm；L3 is projected length of the circumferential cutting edge on basal plane, unit: mm.
The geometric parameter that milling cutter is detected on ZOLLER, universal tool-measuring microscope or other dedicated optics measurer amount instrument, cuts
Cut sword rotating diameter, radial and axial bounce, the jaggedness quality and shank precision size of cutting edge etc..
The polycrystalline diamond composite step multiple cut polishing tool, can be suitably used for various Knife handle structures, various to meet
The needs of machine tool chief axis interface；The geometric parameter of cutter is according to the mechanical performance for processing acrylic or other macromolecule transparent plastics
It rationally designs, small, the stable cutting of cutting bounce, cutting quality of finish is high, and after circumference blade is made into back taper 1:100, cutter is exited
Shi Buhui is the hole wall plucking after having cut polishing；If cutter diameter is smaller (≤4mm), cutting edge is more, holds sword, circumference knife
Sword and chamfered cutting edge each two or more use anti-welding structure, then to enhance edge strength and rigidity；If cutting edge diameter
Larger (>=6mm) then uses positive welding structure；Wherein a blade crosses center 0.2mm, can not only expand on porose acrylic board
Hole and its chamfering can also cut polishing hole and its chamfering on solid acrylic board.
Application characteristic: 1) process acryl surface can reach, light, bright, light transmittance >=91%, surface roughness Ra≤12
~15nm (nanometer)；2) the cutting polishing that cutter clamped one time can complete the bottom hole, hole wall, orifice chamfer of through-hole or blind hole adds
Work；3) it is suitble to produce in enormous quantities in machining center or on building-block machine；4) cutter life is long, and tool change time is reduced, production efficiency
Height, processing quality are stablized, and it is more significant to reduce production cost.
The cutting polishing that the utility model is mainly used for the acrylic product in literary wound industry Visual Merchandising show apparature adds
Work, energy clamped one time cutter completes the through-hole of acrylic or bottom hole, hole wall, the high-precision of orifice chamfer, the bloom of blind hole are cut
Cut processing, saved tool change time, reduce production cost, the hardness of polycrystalline diamond (PCD) material can reach HV75000~
8500 or so, heat resistance is up to 800 DEG C, 5~8 times higher than hard alloy of the cutting speed of permission or more, high production efficiency, quality
Good, under the conditions of machine tool accuracy and enough rigidity, finished surface can achieve the effect that smooth and saturating, light, bright, light transmittance >=
91%, surface roughness Ra≤12~15nm (nanometer)；It is mainly used for processing acrylic, is also capable of processing other high molecular materials
The cutting polishing of bottom hole, hole wall and orifice chamfer, and when high molecular materials such as acrylic are cut opposite high-speed steel and
Hard alloy cutter abrasion wants much slower, and cutting wear at least can be improved 6 times or more.
The utility model consumes in displaying field to acrylic material modern literary wound industry Visual Merchandising and luxury goods
The progress of cutting polishing technology has a very important significance.
The above are merely preferred embodiments of the present invention, it is noted that for those skilled in the art,
Without departing from the concept of the premise utility, several modifications and improvements can also be made, these also should be considered as practical
Novel protection scope, these all will not influence the effect and patent practicability of the utility model implementation.
