This step VI repeats five times, and it is identical with the direction that emery wheel carcass (12) thereon rotates every time that carcass lays post (13), enters next step afterwards；
VII, thicken
Master controller controls the rotation of B motor (2), the carcass making emery wheel carcass assembling mechanism is laid post (13) and is rotated clockwise or counterclockwise 660～690 degree with emery wheel carcass (12) thereon, rotate backward equal angular again, reciprocating rotation is a cycle, each cycle is 1.5～2.5 minutes, and meanwhile master controller controls the electric current density of time control random waveform stabilized current supply output is 250～350mA/dm2；This step continues 160～200 minutes；
VIII, emery wheel processing is completed
Native system is lifted by crane from bath trough removal；
Pull down handling pin (11), take out handling button (10), from framework (1), take out carcass lay post (13) and emery wheel thereon, lay from carcass and post (13) disassembles the emery wheel after each processing；
Clear water rinsing emery wheel 3～5 times.
9. diamond-impregnated wheel automatic sand thickening system according to claim 8, it is characterised in that:
In described step I, first emery wheel carcass (12) is front respectively installs one piece of cathode baffle (9) afterwards with end emery wheel carcass (12), cathode baffle (9) equals to or more than the circular metal plate of emery wheel carcass (12) for diameter, and cathode baffle plate is connected with wiring position；The annular insulation film (15) that internal-and external diameter matches is had with emery wheel carcass between described cathode baffle (9) and adjacent emery wheel carcass (12).
