water wheel rotary transfer machine is a typical mechatronics product which integrates computer technology, automatic control technology, exquisite measurement technology and other advanced technologies. Its control system is complex and expensive, and once it fails, many people stay away because of its "expensive value" and ask maintenance personnel to come out. It wastes manpower, material resources and financial resources, and delays working hours. In fact, for some common operational problems, as long as the operator is diligent in thinking, good at summarizing, and attaches importance to accumulation, it is not difficult to find and solve problems. Now the water wheel rotary transfer machine some common operation problems exclusion methods introduced to beginners reference.

1. In manual mode, the axes do not move

Symptom: During manual operation, the coordinate axis of the machine tool does not move, and the coordinate value does not change, the M, S, and T functions are performed normally, and the system has no alarm display.

Analysis and solution: When the fault occurs, the system does not produce an alarm, and the M, S, and T functions perform normally, according to which it can be preliminarily judged that the CNC system and servo drive should be fault-free. Therefore, it can be analyzed from the manual condition, carefully check the input of the manual arrow key, and the selection of the manual direction are normal, and then carefully observe the "present position" page of the operation panel, and find that the manual speed, actual speed, and feed rate are zero. Confirm that the reason why the axis does not produce manual motion is caused by the zero manual motion speed, readjust the feed speed percentage, and the manual operation will return to normal.

Second, the automatic operation is not in place

Phenomenon: To position the tip of the No. 1 knife to a known point on the workpiece, after the correct input of the relevant instructions under the program input mode (MDI), the M and S instructions are executed normally, the machine coordinate axis moves, the CRT screen displays the correct position, but the tip does not run to the established position, and the system has no alarm display.

Analysis and solution: Due to the normal fixed-point operation process of the machine tool, it did not reach the established position. The occurrence of such faults is usually related to the execution of the knife repair. Check the execution of the tool and find that the tool function is T0103, and the tool No. 1 executes the tool compensation value of the tool No. 3, resulting in the tool tip cannot run to the established position. Enter T0101 in MDI again to rectify the fault.

3. Irregular pitch in thread processing

Phenomenon: When the water wheel rotary transfer machine processes the thread, the pitch of the initial section of the thread is irregular, that is, the so-called disorderly teeth appear.

Analysis and solution: The thread is processed on the water wheel rotary transfer machine, and the actual X axis Angle is interpolated between the Z axis feed. The mess is due to the X axis and Z axis feed can not be synchronized, the machine tool servo system itself caused by the hysteresis characteristics. GSK980T is an economical CNC system, the spindle speed is open loop control, under different loads, the spindle starting time is different, and the spindle speed is unstable, the speed will also have a corresponding change, thread cutting starts from the detection of the spindle position encoder signal after the start, so may lead to the X axis and Z axis feed can not be synchronized. The above problems can be solved by modifying the program.

1, change the anchor point of the thread processing program, so that it is far away from the workpiece, so that the unstable change of the spindle speed is completed in the space, after stability, the tool really contacts the workpiece, and then start threading.

2. Add G04 pause instruction before spindle rotation instruction M03 and thread processing instruction to ensure stable spindle speed before starting thread processing.

Fourth, the processing program can not be executed

Symptom: After the water wheel rotary transfer machine is started, select the name of the processing program and press the automatic run key, the M, S and T functions are executed according to the program command, the coordinate value changes show no abnormality, but the coordinate axes do not move, and the action specified by the program is not executed.

Analysis and solution: When such faults occur, the first thing that comes to mind is to check whether the feed speed and feed green times are zero, and whether the results are normal. Further inspection found that the machine interlock button indicator on the operation panel was on. After the interlock was turned off, the program was executed normally.

Five, halfway to the knife

Phenomenon: In the process of NC turning, a non-reference tool breaks or the tool tip is worn, which affects the machining accuracy. (This example assumes that No. 3 non-reference knife collapses)

Analysis and solution: This kind of failure often occurs when unskilled workers operate the water wheel rotary transfer machine. After the failure occurs, we should immediately press the "pause", "reset", "program back to zero", "Run" and other keys on the operation panel, cancel the No. 3 tool repair, reinstall the appropriate tool at the No. 3 tool position, switch on the power supply, measure the diameter α of the workpiece somewhere, start the spindle, gently touch the surface with the tip of the No. 3 tool, press the "knife repair" key on the operation panel. Enter X "α" at tool offset number 103; Exit the tool, stop the spindle, measure the distance β from a step in the workpiece to the origin of the workpiece, start the spindle, gently touch the step with the tip of the No. 3 knife, press the "tool fill" key on the operation panel, and enter Z "β" at the tool offset number 103. The system automatically calculates the tool repair of No. 3 after reinstallation.
