Description
Technical field
The present invention relates to grinding wheel, especially a kind of manufacturing method of fiber array V-shaped type groove diamond slitting wheel.
Background technology
Fiber array (English is Fiber Array, FA) is to utilize V-shaped groove（That is V slots, V-Groove) an optical fiber,
A branch of optical fiber or a fibre ribbon are mounted on array substrate.Fiber array is that the nuditing fiber part of removing fibre coating is set to
In the V-shaped groove, pressurized device component pressurizes and is bonded by adhesive.In front end, which is accurately positioned, with even
It is connected on PLC.The joint portion of different optical fiber is installed on array substrate.
Fiber array is mainly used to directly transmit image.End face is arranged in the several of needs by numerous optical fiber in sequence
What shape forms fiber array, and the optical fiber arrangement position at array both ends corresponds, and an optical fiber is equivalent to a picture in array
Element, the light image in fiber array one end will be reappeared in the other end of array.Medically various fibre opic endoscopes are exactly with this
What a principle made.
Integrated optical device is widely used in many fields, in the manufacture craft of device, tail optical fiber with
Coupling between chip is one of key technology.Because optical fiber is very thin, when being coupled with chip, fixture is with optical fiber as one
Whole and die bonding gets up, while can increase bond area, improves the reliability of device.Grip size very little, required precision
Also in micron dimension.High purity quartz material is widely used because of its excellent optical property in fiber array.
Fiber array relies primarily on the V slots of precision ruling to realize positioning, and optical fiber spacing is most important detection project, fine
Core spacing includes two Testing index, i.e. lateral distance between fibre core and fibre core（Referred to as Pitch）The longitudinal direction between them and
Distance（Claim Deviation）, it is l=127um/ that the error of the two, which is generally controlled in ± 0.5um adjacent fibers center spacing,
250um, d ∝ 2um, r=125um.
In the processing of fiber array V-shaped type groove, the cutting of saw formula is the current predominant methods for carrying out this process both at home and abroad, accurate gold
Hard rock V-groove abrasive cut-off wheel is main way wherein.Since the technology requirement of fiber array is very high, so to abrasive cut-off wheel
Precision and use condition require also very harsh, very thin thickness itself, usually within 0.2-0.5mm, easily embrittlement or crisp
Disconnected, workpiece rotational frequency is high（25-35Krpm）, linear velocity reaches 120-140m/s, bears prodigious impact force and centrifugal force.It is cutting
Big service load and high cutting heat are born during cutting, and must impose the deionized water more than 1L/min flows from multi-faceted
Carry out pressure cooling.Normally failure is too fast for radial consumption for abrasive cut-off wheel, i.e. arc-shaped is presented in V-type wedge angle too early, causes to make
It is insufficient with the service life or bad for the radial too slow sharpness of consumption, cause to burn knife cut quality variation；Improper failure includes distortion
Deformation, tipping cracking even collapse it is broken forge a knife, so that it is lost cutting function too early.
Since V-groove is for fixing optical fiber, optical fiber must have at 2 points and be stuck on the side wall of slot simultaneously, and such optical fiber is just not
It can move, if the bottom circular arc of V-groove is excessive, cannot accomplish that this point, optical fiber cannot be put into inside, optical fiber meeting completely
It is mobile.V-groove openings of sizes determines the depth that optical fiber is fallen.Too small openings, then the depth that optical fiber is fallen is too shallow, stability
Difference.It is open excessive, then the depth that optical fiber is fallen is too deep, and fixation is insecure.Because of the cutting tool of the existing fiber array V-shaped type groove of processing
In problem present on raw material and structure, low using not only working efficiency, low precision, spring mouth is big, and not environmentally, meets not
Therefore how the actual needs of the fiber array V-shaped type groove of processing solves the cutting processing cutter of fiber array V-shaped type groove, is industry
Interior desired the technical issues of solving.
Invention content
For the above situation, to overcome the defect of the prior art, the purpose of the present invention to be just to provide a kind of fiber array V-shaped type
The manufacturing method of slot diamond slitting wheel, the efficiency that can effectively solve traditional caustic solution processing V-groove is low, and low precision jumps
It is mouthful big, not environmentally the problems such as.
The technical solution that the present invention solves is a kind of manufacturing method of fiber array V-shaped type groove diamond slitting wheel, described
Diamond slitting wheel include alloy matrix aluminum and pilot hole, 2 center of alloy matrix aluminum is provided with pilot hole 1, alloy matrix aluminum 2
