LEVI - d accused of man-machine interface 430 t, LX3V - 1212 host Mr Series PLC application in the grinding machine - Industrial control -

A, profile grinding machine is made of painted or embedded abrasive tool grinding machine for grinding workpiece surfaces. It is mainly used for grinding the workpiece in the high precision plane, internal and external surface, sphere, cylinder, cone, thread surface and other surface. Grinding machine type disc type grinding machine, main rotor mill and various special grinding machine. Grinding machine control system with PLC as control core, the touch screen for the man-machine dialogue interface control mode. Can the man-machine dialogue interface equipment maintenance, operation, failure information such as dialogue with people; Intuitive interface and convenient operation, process control, simple operation. Comprehensive security concerns, abnormal state of wrong operation is invalid. Real-time monitoring, fault, error alarm, maintenance is convenient.

2, the control system mainly adopts LEVI - d accused of man-machine interface Host the LX3V - 430 t, PLC 1212 Mr. Brief plan is as follows:

by the touch screen can select manual mode and automatic mode. Go PLC controller communication control inverter frequency speed to achieve the purpose of a millstone. PLC reading grating ruler data to show that the thickness of the abrasive, the PLC to control movement.

program are briefly introduced HMI:

automatic picture

after the plate in place on the light, can be started.

click the start button, spindle and water movement, gently press start timing action, until the end of the timing light pressure. Medium voltage start timing action, until the end of the medium voltage timing. Pressure began to action, until the end of the time pressure. The current value of thickness to the thickness of the set value, the end of the action, the spindle pump stop working. And it is too 1 minute alarm prompt. End of the alarm automatically.

click the stop button, in the process of start to end all working condition. Not in the process of start switch to the manual picture. Manual picture

1. Water pump: click on an open button, the pump work, click close button again, the pump shut down.

2。 Spindle: click the open button a spindle, the spindle work, click on the spindle off button again, the spindle to shut down.

here you can set the formula 20 groups.

number formula: select group, to choose from, 1 - 20)

save parameters in each group. The value of modified formula, can call Settings. Click save in written to the PLC.

PLC program:

sequential control, timing control.

4, project summary this equipment mainly by abrasive wheel speed control a millstone, according to the thickness of the grating scale testing the abrasive conditions, and the grinding process is pressure of the back pressure setting, to control the abrasive rev. Stop.
