The running of valve SV-B6, electromagnetic valve SV-C8 and grinding head 5.
The work of each ingredient of the present utility model is as follows:
1st, lapping liquid bucket：Lapping liquid is constantly reclaimed in process of lapping, it is to avoid waste lapping liquid and play economic and environment-friendly work
With.
2nd, electromagnetic valve SV-A：The electromagnetic valve is in open mode in process of lapping, terminates in grinding and flush pipe is passed by
It is closed in journey, flow that can be as needed carrys out the size of electromagnetic valve for adjusting aperture.
3rd, electromagnetic valve SV-B：The electromagnetic valve is closed in process of lapping and in grinding terminal procedure, is rinsing
It is closed during pipeline.
4th, filter：The foreign body or residue of lapping liquid appearance are filtered out, prevents occurring the broken glass of fragmentation in process of lapping
Glass is flowed in lapping liquid.
5th, effusion meter：Flow rate upper limit value and flux lower limit value are set, and feedback real-time traffic information provides corresponding signal.
6th, grinding head：When automatic grinding is started when lapping liquid flows out from grinding head, grinding head starts to push to rotate
Mode grind.
7th, electromagnetic valve SV-C：The electromagnetic valve is closed in process of lapping, is in during flushing line and beats
Open state.
Operation principle of the present utility model is：Start grinder and start grinding, now electromagnetic valve SV-A is opened, and aperture
