Description

"Tunnel Gate Logic"
CNC EDM Tunnel Gate Chucks
This system has been developed specifically for the
CNC EDMing of plastic injection mold tunnel gates (sub gates) (submarine 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 angles from
0 to 90 degrees in 5 degree increments
with it's unique indexing system. The unit has graduations every
5 degrees
with a reference pin for easy angle setup.
No sine plate required to true in the inclined angle.
The TGL gate chuck can be sold with a tool length offset probe when multiple chucks are used.  The teardrop probe attachment makes it possible to set your tool length offsets so that all the holders in the group are identical.  You locate one holder to your work piece with one of the tunnel gate electrodes and all the other holders will repeat to your programmed locations and depths.
The holders are designed to use
3/8 square electrode material
.  You will end up grinding a group of electrodes to your desired included angle using a Harig type grinding fixture or similar.  Also,
these electrodes can also be purchased from us in a variety of standard included angles
.   The TGL CNC EDM chuck is also available with an optional 3R coin holder.  The chuck can c-clamp to a rail type holder or the shank can mount in any EDM holder that will clamp a 1"square body.
IMPORTANT NOTICE TO PURCHASERS:  The listed 5 buy it now price is for a Tunnel Gate Logic gate chuck without a 3R coin adapter.
