Can the CNC lathe tool holder not start? Use these seven small methods to solve (below)

Third, the knife holder lock is not tight

1. The location of the transmission disk is not aligned.

Disassemble the top cover of the tool holder, rotate and adjust the position of the transmitter plate so that the Hall element of the tool holder is aligned with the magnetic steel to stop the tool position in an accurate position.

2. The system lock time is not long enough.

Adjust the system lock time parameter (the new tool post lock time t is 1.2s).

3. The mechanical locking mechanism is faulty.

Disassemble the tool holder, adjust the horizontal lathe, and check if the positioning pin is broken.

Fourth, the knife holder runs continuously and is in place.

1. Since the tool holder can run continuously, there is less possibility of mechanical failure, mainly from electrical inspection.

2. Check if the in-position signal is sent. If there is no in-position signal, it is a fault in the sending disk.

3. It can check whether the elastic contact of the sending plate is worn out, whether the ground wire of the transmitting plate is broken, bad contact or missing. At this time, it is necessary to replace the elastic piece contacts or re-repair, and perform line troubleshooting corresponding to the contact condition of the relay in the line, the contact condition of the in-position switch, and the line connection.

Fifth, the knife holder is over-shooting or not in place.

1. The knife holder overshoots.

The mechanical cause of this failure is more likely, mainly because the rear-facing device does not work. First check if the positioning pin is flexible and the spring is fatigued. The locating pin should be repaired at this point to make it flexible or to replace the spring. Secondly, after the inspection, the connection between the ratchet and the worm is broken. If it is disconnected, the coupling pin needs to be replaced.

If overshoot still occurs, it may be because the tool is too long and too heavy, and the locating pin spring with a slightly larger elastic modulus should be replaced.

2. The tool holder is not in operation (sometimes the position suddenly stops).

This fault is mainly caused by the misalignment of the contact of the transmitting disc and the contact of the elastic sheet, that is, the position of the glue board of the knife position is fixedly offset. Firstly, the position of the transmitting plate and the elastic piece contact are re-adjusted and fixed firmly. If the heavy duty lathe machine’s fault cannot be eliminated, the transmission clamp nut may be loose and the position may be moved.

Sixth, the input tool number can rotate the tool holder, directly press the tool change button, the tool holder can not rotate

1. The Hall element deviates from the magnetic block and is placed in front of the magnetic block. When the manual key is changed, the tool holder detects the position information of the tool holder as soon as it rotates, and then immediately reverses the tool holder. At this point, check that the Hall element on the knife tray is off position and adjust the position of the transmitter to align the Hall element with the magnetic block.

2. The manual tool change button is out of order. At this time, the manual tool change button can be directly replaced.

CNC Lathe Machine

Seventh, the tool number of the tool is not the same as the tool number displayed in the lathe system.

1. This situation is generally a new problem caused by maintenance. One possibility is that the magnetic block is not in the right position; the other may be the connection problem of the circuit inside the tool holder.

2. The magnetic block of some tool holders is in the upper cover of the tool holder.

3. The tool holder circuit problem can not generally solve the fault by simply changing the position of the magnetic block.

According to the above reasons, analysis and inspection methods and solutions, it is helpful to find the cause of the fault in a timely and effective manner and quickly eliminate the fault. Economical CNC lathes are more commonly used machine tools. In the maintenance process, it is not only necessary to repair well, but also to repair quickly. To do a good job in machine tool maintenance, not only to master the theory, but more importantly, to continuously improve and accumulate in the practice to accumulate rich maintenance experience, so that the CNC lathe tool holder can be repaired efficiently.
