In daily production and processing, machine failures are still relatively common, especially for precision equipment such as CNC lathes, which have many components and relatively precise program

settings. If there is a slight error, it will remain. At this time, we should first find out the cause of the fault, but in the actual operation process, many cases use the elimination method to

find the fault. Today we will explain to you the troubleshooting process of CNC lathe motor troubleshooting.
(1) The phase sequence of the three-phase power line is reversed. Troubleshooting method: immediately cut off the power supply and adjust the phase sequence of the three-phase power supply. (2) The

voltage is too low. Troubleshooting method: wait until the power supply voltage is normal before using or add a voltage stabilizer to provide a voltage stabilized power supply. (3) The motor is

damaged. Troubleshooting method: replace the motor. CNC lathe is a high-precision and high-efficiency automated machine tool. Equipped with a multi-station turret or a power turret, the machine

tool has a wide range of processing technology performance, can process linear cylinders, oblique cylinders, arcs and various threads, grooves, worms and other complex workpieces, has linear

interpolation, arc interpolation and various compensation functions, and plays a role in the mass production of complex parts. The calculation method of the thread cutting amount of the CNC lathe,

both internal and external threads are: the number of teeth of ZG1/8 thread n=28, the pitch t=254/28=0907, the cutting depth (tooth height) h=064033t=0581. In this way, it can basically be

programmed, but it is necessary to pay attention to the difference R between the large and small diameters of the tapered pipe thread.
Preliminary judgment method of tool holder failure 1 Listening When receiving a maintenance request, you should listen carefully to the phenomenon reflected by the operator, and ask clearly about

the doubts in order to eliminate the problems caused by human factors. Listen to the sound of the tool holder operation on site to observe whether there is abnormal noise. See if the tool holder

operation process is normal. This cycle can be used for intermittent cutting of the end face. If Z (W) and K, D are omitted, the action of the X axis can be used for intermittent cutting of the

outer diameter groove. This device is mainly used to collect and transport various rolled, lumpy, strip, and block chips, and is widely used in various. There are several types of short circuits,

and how to eliminate them. (Mainly machine tool troubleshooting). Phase-to-phase short circuit, the terrible thing is that the switch should not be sent, use a multimeter, and measure the short

circuit 2 to the ground one level at a time on the phase line, which is difficult to eliminate. Leave the machine tool 0 line and the ground line suspended, and check them one by one.
It is best to use machine clamps for CNC. It reduces the number of tool setting and sharpening time and greatly improves production efficiency. When buying thread blades, different pitches are

different. You have to buy blades with corresponding pitches. It is best to have CNC lathe thread tool specifications trimming (polishing), so that the threaded threads will look better. Thread

blades have Haishu CNC lathe thread tool specifications F, etc. can be used.
The above is the troubleshooting process of CNC lathe motor. I hope the above explanation can be of some help to you in dealing with CNC lathe motor failures in the future.
