First, the spindle grabs the number of the chaos When the problem occurs, the spindle tool is removed, the No. 1 knife sleeve is transferred to the tool change position, the specific operation is as follows:
Incremental encoders provide speed, direction and relative position feedback by generating a stream of binary pulses proportional to the rotation of a motor or driven shaft. Lander offers both optical and magnetic incremental encoders in 4 mounting options: shafted with coupling, hollow-shaft, hub-shaft or bearingless. Single channel incremental encoders can measure speed which dual channel or quadrature encoders (AB) can interpret direction based on the phase relationship between the 2 channels. Indexed quadrature encoders (ABZ) are also available for homing location are startup.

1. System → PMC → parameter → counter, counter C1—PRESET input the tool magazine capacity value, then input the current tool position, C2 can be ignored. System → PMC → parameters → data table, OFFDATA input value (tool magazine capacity value +1)
3. Press FGDATA soft key, DO~Dn input 0~n (corresponding tool number) in sequence. Second, the main reason for the collision of the knife failure is:
1. Sudden loss of the spindle tightening knife signal causes the spindle to stop rotating. X and Y still move. At this time, the plc program can be modified or the tight knife switch can be adjusted to make it press properly. At the same time, check whether the solenoid valve of the tight knife works normally. User program has a problem 3. The user uses the tool length correction, but selects the plane to select the non-G17 plane. FANUC 0I checks whether the part signal has been lost or adjusts the tool clamping switch. 3. The spindle has a knife drop phenomenon. The machine can't catch the knife. Generally, the fault can be eliminated by the following check. Check if the air pump pressure is normal. Check whether the air flow of the machine tool spindle is smooth, whether there is air leakage, whether the vertical movement of the spindle cylinder is normal, whether the loose and the card cutter switch are normal. Check the cylinder for air leaks, repair cylinder piston and cylinder seals. Check whether the claw of the machine gripper is open, adjust whether the screw under the gripper cylinder is up to the upper end of the gripper claw, and adjust the upper end of the gripper claw. Check if the gripper of the machine tool is worn. 4. The cutter disc cannot be rotated. The reason may be that the motor protector of the tool magazine is moving, or the brake is not open, or the cutter drive is too heavy. You can check whether the thermal protection in the electric cabinet trips. If the electrical is normal, the mechanical transmission may be faulty. Generally, the cutter drive bearing may be stuck or rusted. The motor temperature is too high, the cutter head does not move, and the tool change button LED is not displayed.
Fifth, the tool magazine can not enter and exit this situation can be checked by checking the following parts. Whether the motor power supply is normal and the motor is rotating. Whether the knife change tool proximity switch is normal, the tool change signal and the tool bank ready signal are normal, and there is no line virtual connection phenomenon. Whether the relay works normally and the line has a virtual connection. Whether the tool magazine turntable, the transmission mechanism is flexible, whether there is any jamming phenomenon, or the spindle's quasi-stop position misalignment phenomenon 1. Open the spindle case and disconnect the spindle from the motor. You can adjust the exact stop by turning the spindle by hand.
2. The quasi-parking position can be adjusted in the operating system. The specific method is as follows: In the MDI mode, press the setting button (OFS/SET), write the parameter to “set to 1â€, and then press the parameter button to find the quasi-stop parameter “4031â€. ", according to the increase and decrease of the quasi-stop parameters to adjust.
In addition, for the tool change, in addition to the above reasons, the tool change is not normal, if the loose clamp solenoid valve is broken, the claw spring is damaged, the air pressure is small, the tool cylinder is not working properly, the tool cylinder is in the water, the loose cylinder is the piston rod. The phenomenon of hitting with the loose knife rod and the poor cylinder seal may also cause the tool change to be abnormal. When the above situation occurs, the spring, electrical parts, air pipe, tie rod, cylinder, etc. should be separately repaired.
