CNC tool length calibration sensor for wood router machine is a sensor for tool offset setting purpose. It is always equipped with cnc router with auto tool changer. When using multiple router bits on a CNC operation, the Z-axis is always the goofy axis because, for instance, the lengths of the tools are all different and the distance the tool is inserted into the spring collet can vary widely. If without tool calibration sensor, we have to calculate the length difference of each tool and set offset in the controller before every operation starts. Undoubtedly, this process will be time costly. While, the  tool length offset sensor optimizes this process. With the sensor, you will load the first tool, then the machine will capture the tool length with the sensor before you touch that tool off to the top of the part. This will establish the z-axis origin and you will only have to touch off the top of the part this one time. On each tool change, the machine will shut off the spindle and drive out to the front of the machine to allow for easy tool change access. The machine will then drive over until it is above the tool sensor, will bounce off of that sensor, will then continue with the cutting process using the new compensated tool length offset.  In a word, tool length calibration sensor makes the operation simple and increases the production efficiency.
