A finger tool holder seat is part of a CNC router tool system that holds the tool holder securely in place during operation. The tool holder is part of the tool that holds the cutting bit or other cutting tool in place.
The Auto Tool Change system is a feature of some CNC routers that allows the machine to automatically change out cutting tools during operation. The tool holder seat helps to ensure that the Auto Tool Change system can pick up and return the tool holders safely and efficiently by providing a secure and stable location for the tool holder to be held in place.
In other words, the finger tool holder seat is a key component of the CNC router parts that helps ensure that the tool holders are held securely and can be changed out quickly and safely during the operation.
