This device helps to improve efficiency of the machining process. If you use multiply tools in one project you have to change manually the machine settings every time you swap the tool - it happens, not only because every tool is different, but most of all because when you change the tool you can't be sure that you put it in the appropriate deepth in the collet. With our gauge you don't have to do it any more. The tool measuring sensor (Z height) will automatically adjust the tool height parameters to the same depth as previous tool, so that machining can conitinue fluently...
