SBR, reversion circuit are connected, and reversion control contactor KMR coil obtains electric, the motivation that conducts electricity slowly, grinding machine operation, when grinding machine intermittent duty
When, reverse inching turning control switch DSBR, the normally opened contact closure of reverse inching turning control switch DSBR are pressed, a normally-closed contact breaks
It opens, reversion circuit in this way is connected, and reversion control contactor KMR coil obtains electric, slow transmission device motor, grinding machine operation, instead
Turn the normally opened contact closure of control contactor KMR, a normally-closed contact of reversion control contactor KMR disconnects, but reverse inching turning
A normally-closed contact of control switch DSBR be disconnect, reversion circuit do not formed it is self-locking, when unclamp reverse inching turning control switch
DSBR inverts control contactor KMF power loss, and slow transmission device motor, grinding machine are out of service, inverts control contactor KMR
A normally-closed contact disconnect, accordingly even when accidentally press normal inching turning control switch DSBF, rotate forward circuit will not connect, guarantee grinding machine
It operates normally；
Reverse inching turning control switch DSBR need to be only pinned when maintenance, grinding machine rotates forward operation, finds out friction point, release button, grinding machine
Stop in time to friction point, operation maintenance.
