This system has been developed specifically for the CNC EDMing of plastic injection mold tunnel gates. The current systems that are now available are not made for easy angle setting or for easy tool length offset settings when using multiple tool holders.
This system allows for the quick setting of the tunnel gate inclined angle from 0 to 90 degrees in 5 degree increments with it's unique indexing system. The 5 degree graduations are set with a locating pin which makes for quick and easy angle setups. No sine plate required to true in the inclined angle.
