The structure of the High Precision Automatic grinding machine of the utility model couples referring to the technical solution, does not repeat separately.
Small roller is placed on the support wheel of the support of the vertical direction between grinding wheel and guide wheel when processing, and small roller does not have to top
Needle is felt relieved and is supported and using ground outer circle itself as positioning datum.Grinding wheel and guide wheel rotate in same direction, guide wheel peripheral speed
It is very low, it is 20-30m/min, the peripheral speed of abrasive grinding wheel is 60-80 times of guide wheel.Small roller is between grinding wheel, guide wheel
It is passively rotated under friction force effect, there are larger linear differentials to realize its material for the contact area of small roller and abrasive grinding wheel
The grinding of material removes.
Graphite wheel is first accomplished to the profile opposite with forming grinding wheel before finishing, grinding wheel is connected into anode and is connected into graphite wheel
Cathode, grinding wheel is relatively rotated with graphite wheel when finishing, to water-soluble emulsion is sprayed between grinding wheel and graphite wheel, by adjusting voltage
And pulsewidth generates pulse spark electric discharge between grinding wheel and graphite wheel, carries out galvanic corrosion to the metallic bond on grinding wheel, makes new
Abrasive grain exposes metallic bond surface and forms certain projecting height, you can reaches the purpose of integer, this mode is molded essence
Degree is high, efficient and at low cost, and the grinding wheel after finishing has good grinding performance, improves the grinding accuracy and matter of small roller
Amount.
First will the profile opposite with forming grinding wheel be accomplished by the inner ring surface of dressing copper ring electrode before dressing, grinding wheel is connected into just
Pole and dressing copper ring electrode is connected into cathode, grinding wheel rotates when dressing, to injecting electrolyte between grinding wheel and dressing copper ring and connecing
Cell reaction occurs in the case of energization source, metallic bond material when pre- dressing starts in grinding wheel is detached from sand due to electrolysis
Wheel, while oxides-containing iron is stacked on wheel face and forms the oxide film layer with insulating property (properties), sull
Layer continuously decreases so that acting in conjunction with upper Faradaic current, and electrolysis decrease can be to avoid the excess of metallic bond material
It is lost in.When carrying out grinding, wheel face abrasive grain is worn again, and at the same time oxide film layer is also gradually removed,
The removal of oxide layer film layer causes Faradaic current to increase again, and electrolysis restarts, and repeating the above process makes grinding wheel obtain again
Obtain height of grain.It can be achieved with stable high-efficiency grinding processing in cycles.
