Z37 radial drilling machine control circuit

It is mainly composed of three parts: spindle
rotation, rocker arm lifting and column elasticity
. The power supply of the electrical control box
is powered and grounded by four bus rings HTH installed in the rocker lifting L structure box
.
The actions of the electrical components in the machine tool control circuit are all completed by the cross switch
SAi.
Only one pair of the four pairs of cross switches can be connected at any time, so that the rocker arm and the spindle motor cannot operate at the same time. The speed change and forward and reverse operation of
the spindle
are realized through the mechanical structure. Its circuit control principle is similar to that of the inching circuit. The
only difference is that the button is replaced by the contact of the cross switch . The electrical components
of the control circuit are shown in Table 5-3.
