EFFORTLESS CHATTER ELIMINATION IN MACHINING FROM NAKAMURA-TOME
When you come across chatter, how do you get rid of it?
Chattering in machining is the unwanted harmonic vibration of a workpiece and a cutting tool caused by several reasons. Chatter ruins machining precision and reduces productivity. Even though your machine has high rigidity, it happens. Here are a few things that you can do to mitigate chatter:
- Fix work holding
- Shorten up your tool holder
- Shorten the stick out of your tool
- Change the programming
- Modify the cutting speed and feed rate
- Add fixturing and support for the part
However, it is hard to find out the specific reason for the vibration. Even if you could eliminate chatter, another problem would occur. For example, when you change the cutting speed, it often affects your cycle time.
Therefore, as machinists, chatter is our common enemy. We want to mitigate it as soon as possible and do not want to ruin our day. This is why Nakamura-Tome’s Chatter Canceller is a wonderful feature; it is a handy, effortless and a quick solution against chatter.
Why Chatter Canceller?
The Chatter Canceller suppresses chatter by accelerating and decelerating the speed of spindle rotation periodically. When chatter occurs during machining, you may usually adjust the spindle override to avoid vibration. However, you need to be there in front of the machine to operate the control panel. This function automates such operations.
The Chatter Canceller stands out with its easy programming. It can be executed by inserting two lines of M code between a machining command.
Of course, no matter how good the machine or the program is, if the work holding is not good, vibration will be generated physically. Therefore, the work holding is fundamentally important. In addition, chatter can be solved by changing the cutting condition of OD and ID turning or adjusting the length of the stick out of the tool, but if you use the Chatter Canceller, you can easily eliminate the vibration and reduce the impact on the cycle time and tools. So, we strongly recommend you use this function.
The Chatter Canceller is standard equipment on models except the TW-8, SC-200, SC-200L, SC-250, SC-450 and SC-450L. In addition, this function has been equipped with machines since May 2021.
