Description
Technical field
The invention belongs to the manufacturing field of emery wheel, and in particular to a kind of ultra-thin ring plate precision Special device for bonding and its bonding
Technique.
Background technology
In photoelectric communication field, the Precision Machining of some vital parts will use a kind of abrasive cut-off wheel of 3A1 types, such as Fig. 1
It is shown.The abrasive wheel is made up of ultra-thin ring plate 3 and the two parts of matrix 1, and both pass through bonding way（That is glue-line 2）It is connected and forms one
Individual entirety, wherein ultra-thin ring plate 3 overhangs out, the width of matrix 1 is in 3-5mm.Ultra-thin ring plate 3 is the work of sintered type diamond abrasive
Layer, mainly play mill and cut, ring plate ring width is between 8-10mm, and thickness is in below 0.15mm, extremely thin, poor rigidity；Matrix 1 is
Aluminium, it is relatively thick（About 4mm）, mainly play a supportive role, enhancing abrasive cut-off wheel rigidity, while can make and match somebody with somebody with machine tool chief axis
Set, is conveniently operated with.
The emery wheel requires end face run-out of the abrasive material working lining with respect to matrix hole footpath axis within 0.02mm.This is to adhered
There is following technology difficulty for the making of 3A1 abrasive wheels：Abrasive material working lining is ultra-thin ring plate, and any unbalance stress easily deforms；
Uncontrollable factor be present in bonding solidification process（These factors are the persistent ailments of technique for sticking, and industry level can not solve at present）
Ultra-thin ring plate shape abrasive material deformation can be just influenceed, as bonding agent mixes uneven, rubber thickness asymmetry, glue-line with curing agent
Consistency is inconsistent, and then when causing jelly cure shrinkage, contraction state is inconsistent everywhere for glue-line, is bonded jelly cure shrinkage,
It has certain effect of pullling to ultra-thin ring plate abrasive material, and due to being bonded the contraction of jelly and uneven, therefore bonding agent is to mill
The bed of material to pull active force also uneven, and ring plate abrasive material is extremely weak, and rigidity is very poor, so bonding glue shrinkage is easy to
Ultra-thin ring plate abrasive material is caused to deform；There is no effective means after bonding solidification to correct the deformation of ultra-thin ring plate.Ultra-thin ring plate
As long as deformation, the jitter values of emery wheel are easily overproof, therefore above-mentioned problem constrains the batch production of the abrasive wheel.
The content of the invention
