Surface simultaneously forms profile required for grinding small roller (14), that is, can reach the purpose of online repairing type；
When the increase of its surface abrasion chamfered shape error needs dressing to graphite wheel (5.1) after a period of work, dressing blade
(15.1) it is moved down under the drive of graphite wheel dressing motor (15.9), dressing is carried out to high-speed rotating graphite wheel (5.1),
It, can will since the chamfered shape of dressing blade (15.1) has accomplished the profile opposite with profile needed for graphite wheel (5.1)
The profile of graphite wheel (5.1) accomplishes required shape；
The inner ring surface of dressing copper ring (7.1) electrode is first accomplished into the profile opposite with forming grinding wheel (6.3) before online dressing, by sand
Wheel (6.3) is connected into anode and dressing copper ring (7.1) is connected into cathode and is adjusted between dressing copper ring (7.1) and grinding wheel (6.3)
Gap, the gap is electrolysed gap condition necessary to online dressing, when dressing grinding wheel (6.3) rotate and to grinding wheel (6.3) and
Dressing copper ring injects electrolyte between (7.1), and cell reaction, grinding wheel when pre- dressing starts just occur when powering on
(6.3) metallic bond in is detached under electrolysis, and simultaneous oxidation object is stacked on grinding wheel (6.3) surface and forms tool
There is the oxides-containing iron film layer of insulating property (properties), oxide film layer to act on the Faradaic current on metallic bond gradually
Reduction causes its electrolysis to weaken, to avoid the excessive bleed of metallic bond and dressing grinding wheel (6.3) is to profile；
It is worn as the abrasive grain for continuing and making its surface of grinding wheel (6.3) grinding small roller (14) process generates, and grinding wheel at this time
(6.3) oxide film layer on surface continues gradually to be removed again, causes the increase of Faradaic current again, electrolysis is again
Start and the metallic bond in grinding wheel (6.3) is promoted to be detached from again, newly-generated oxide film layer makes to act on again
Faradaic current on metallic bond, which gradually decreases, causes its electrolysis to weaken, and avoids the excessive bleed of metallic bond again
And dressing grinding wheel (6.3) is to profile；Online dressing in cycles has remained grinding wheel (6.3) to profile, pole
The high-efficiency grinding processing of small roller (14) is improved greatly.
