The cutting edge includes symmetric part and non-symmetrical portion, and the symmetric part setting is described asymmetric in superhard knife ontology upper end
Part is arranged in symmetric part upper end, and three is structure as a whole.
Preferably, non-symmetrical portion includes left side cutting edge and right side cutting edge, the folder of the left side cutting edge and blade tip bisector
Angle is β 1, and β 1 is 2 degree, and the right side cutting edge includes upper cutting edge and lower cutting edge, and the angle of the upper cutting edge and blade tip bisector is β
2, β 2 be 2 degree, and the angle of the lower cutting edge and blade tip bisector is β 5, and β 5 is 8.5 or 9 degree.
Preferably, the angle of symmetric part and superhard knife ontology side be β 3, β 4, β 3, β 4 are 8.5 or 9 degree.
Preferably, superhard knife ontology and cutting edge are the superhard wolfram steel material of ultra micron.
A kind of production method of the superhard knife cut off for chip, light guide plate, it is characterised in that: include the next steps
S1: the superhard wolfram steel parent of ultra micron is subjected to subzero treatment, eliminates stress；
S2: by wolfram steel materials'use special tooling and grinding machine, matrix required for superhard knife is formed, thickness control is 0.1/
0.15/0.2/0.4mm；
S3: production cutting edge carries out precise finiss, forms it into symmetric part or non-symmetrical portion；
S4: R processing will be carried out at cutting edge, can significantly prolonged the service life.
Preferably, it is to carry out R production using W3.5 diamond paste, make cutting edge tip at R shape that R, which handles detailed process,
Shape.
Preferably, subzero treatment detailed process is the superhard wolfram steel material mother of the specific ultra micron that will pass through high temperature sintering
Body carries out temperature curve processing in 72 hours in the environment of -200 degrees Celsius, can effectively eliminate material stress.To obtain more
Stable cutter material.
The present invention has an advantage that cutter of the present invention according to using product object to design different angle automatchings, designs
Symmetry angle and asymmetric angle, prevent chip from chamferring；And when being checked under amplifying 200 times, cutting edge non-notch, cutting edge straightness
0.005 μm (guaranteeing that miniaturized products are sufficiently cut off), angle tolerance meets +/- 0.5, and cutting edge is handled using R, and subzero treatment is prolonged
Long life is to 200000 times or more.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
Shown in referring to Fig.1, a kind of superhard knife cut off for chip, light guide plate of the present embodiment, including superhard knife ontology 1
With cutting edge 2, the cutting edge 2 is arranged on superhard knife ontology 1, and the two is structure as a whole, and the cutting edge 2 includes 21 He of symmetric part
Non-symmetrical portion 22, in superhard 1 upper end of knife ontology, the non-symmetrical portion 22 is arranged in symmetrical portion for the setting of symmetric part 21
Divide 21 upper ends, three is structure as a whole.
The all parts of the present embodiment are explained:
