1. This trainer mainly consists of steel and aluminum structure bench, hanging panel, power supply unit and semi-physical surface grinding machine. The machine bed is made of casting material.
2. Various motion controls can be achieved by the operation of electrical part, such as grinding wheel starting and stopping, workbench reciprocating motion, grinding carriage lifting motion, cooling pumpstarting and stopping, limiting position protection and so on.
3. With related testing points on panel, all the connection points of lathe electrical circuit can be measured, which is convenient for students to detect faults.
4. 16 fault phenomena training.
5. Safety protections: Ground protection , leakage protection, safety in accordance with related standards.
