Performance characteristics of MZ3A/MZ3B boring machine
MZ3A/MZ3B boring machine adopts automatic control. During the working process, it clamps the workpiece pneumatically and feeds the tool pneumatically. It has the function of processing three rows of multiple holes at one time, and can be operated continuously for multiple times at one time and display the total number of processing times on the control panel.
MZ3A/MZ3B boring machine is mainly used in the woodworking industry. It can process mortise and tenon for many wooden products. It is a necessary intelligent machine in many furniture factories.
Common faults of MZ3A/MZ3B boring machine
1. The stop indicator light does not light up when the power is turned on. We should carefully check the power supply, transformer, fuse, indicator light and circuit.
2. Press the start button, the start button indicator light does not light up, and the stop button indicator light does not go out. At this time, we should check whether the emergency stop button is reset, and whether the stop button and start button are in good contact. Whether the drill selection knob is in the OFF position and the contact is good, and whether the relay absorbs electricity and protects itself.
3. When trying manual operation, all cylinders do not move. At this time, check whether the open point of the relay is closed and in good contact.
4. In automatic mode, there is no response when the foot switch is pressed. We should check whether the knob of the cylinder is set to the OFF side, whether the contact is good, and whether the circuit is powered. At the same time, we should also check whether the foot switch is in good contact, whether the air circuit and air pressure are normal, and whether the drill bit is rotating.
5. After the motor is started, the cylinder does not extend. At this time, we should check whether the relay is energized and energized. If it is not energized, check whether the open point of the connector is closed and the contact is good. Check whether the contact of the alternating linkage conversion switch is good, check whether the closed point contact of the relay is good, and check whether the manual button switch is set to automatic and the contact is good. Check the relay. If it is energized and energized, check the quality of the limit switch, whether the adjustment is appropriate, and whether the wiring is correct. Check whether the delay time of the time relay is appropriate.
6. If the cylinder does not retract for a long time, we should check whether the delay time of the time relay is too long and whether the limit contact is poor.
7. The cylinder frequently reciprocates in a short distance. At this time, check whether the self-protection points of the vertical and horizontal relay tubes are in good contact.
