Teaching aid equipment,Typical Machine tool Control Circuits Training and Evaluation Device(eight machine tool circuits)
1.System overview
XK-JCG10C typical machine tool control circuits training and evaluation device adopt normal electricity cabinet as
the main cabinet(mainly consider being in accordance with actual work)It make rational use of the double-sided space of cabinet, each cabinet has eight different kinds of machine circuits. It is C6140 center lathe
electrical control training and electrical circuit troubleshooting evaluation,X62W universal milling machine
electrical control training and electrical circuit troubleshooting evaluation,Z3035 radial drilling machine
electrical control training and electrical circuit troubleshooting evaluation,M1432A cylindrical grinding machine
electrical control training and electrical circuit troubleshooting evaluation,M7130 flat grinder electrical control
training and electrical circuit troubleshooting evaluation,T68 boring machine electrical control training and
electrical circuit troubleshooting evaluation, double housing planer electrical control training and electrical
circuit troubleshooting evaluation and overhead traveling crane electrical control training and electrical circuit
troubleshooting evaluation, respectively, and thus to implement training functions of eight machine circuits in
one cabinet. Not only have rational layout and save cost, but also the circuit that are installed inside the cabinet
are artistic and normative science. The device is equipped with leakage and short-circuits protection and emergency switch to guarantee the students’ safety. The training device adopt the CAN
bus intelligent evaluation system to evaluate and meet the requirement of skill training and evaluation. The
device all adopt application circuit of actual industry, so it is reliable and long lifetime. By the system, teachers
can do on-line monitoring ,long-distance fault setting, self-locking and self-scoring in the process of students’ doing experiment.
