Failure phenomenon: lathe electric knife holder lock is not tight
The cause of the fault and the corresponding processing method:
1 The position of the sending tray is not aligned: remove the top cover of the knife holder, rotate and adjust the position of the sending tray, align the Hall element of the knife holder with the magnetic steel, and make the knife position stop at the exact position.
2 The lathe numerical control system locks the time not to be long enough: Adjusts the system to lock the time parameter (the new knife holder anti-locks the time t=1.2s then).
3 Failure of the lathe mechanical locking mechanism: disassemble the knife holder, adjust the machine, and check whether the positioning pin is broken.
Symptom 2: The cutter number of the electric tool holder keeps rotating, and the remaining cutter positions can rotate.
The cause of the fault and the corresponding treatment method 1 The damage of the Hall element of this position knife: Confirm which position of the knife makes the tool post rotate nonstop, input the order and rotate the position of the tool on the system, use the multimeter to measure the position signal contact pair of 24V If there is no change in the voltage of the contact, if there is no change, it can be determined that the position of the knife Hall element is damaged, replace the sending disk or Hall element
2 The signal line of this knife position is disconnected. As a result, the system cannot detect the bit signal: Check whether there is a disconnection between the tool signal and the system connection.
3 The system's location signal receiving circuit has a problem: When the Hall element of this location is determined to be no problem, and the connection between the location signal and the system is no problem, the mainboard is replaced.
