A variety of measures can be taken to block noise in CNC vertical lathes. The following are some specific suggestions:

1. Use a protective cover for noise reduction treatment: Each wall panel of the CNC vertical lathe protective cover is provided with a support frame, and the frame is fitted with a sound-absorbing thin plate parallel to the wall panel where it is located, so that the wall panel, support frame and The sound-absorbing thin plates surround the sound-absorbing cavity. There are also several sound-absorbing spikes densely covered on the sound-absorbing thin plate. Each sound-absorbing spike is hollow and has several sound-absorbing holes evenly distributed on its outer wall. This design can effectively absorb and weaken various operating noises generated during high-speed cutting of the bed.

2. Adjust the parallelism between the spindle axis and the motor axis: When facing the noise caused by the unbalanced centrifugal force when the two synchronous belts rotate repeatedly, the CNC vertical lathe can adjust the parallelism between the spindle axis and the motor axis, thereby reducing the noise.

3. Ensure the rotation accuracy of the pulley: If the balance accuracy of the CNC vertical lathe reaches G2.5, the noise problem caused by this reason can be effectively solved.

4. Use isolation transformer: CNC vertical lathe isolation transformer is an anti-interference device that enables interference-free operation between devices and electrically isolates circuits, thereby effectively reducing noise.

5. Optimize the electrical layout: for example, use shielded wires and shorten the length of the transmission lines for analog signals, ground the shielding layers on both sides of the cable that drives the motor, separate signal lines from power lines, and use shielded twisted pairs for control signal lines. Line processing, etc.

In addition, you can also take protective measures from the input part of the CNC equipment to prevent the entry of noise; install an absorption circuit in the inductive load to prevent the generation of noise; and do a good job of grounding, because some equipment in the CNC must be in accordance with the regulations in the manual Carry out grounding treatment to effectively prevent certain factors from interfering with the machine tool.

To sum up, noise blocking involves many aspects, ranging from mechanical structure to electrical layout. It is recommended to choose appropriate blocking measures according to the specific situation, and seek help from professional technicians if necessary.
