EDtapper

The revolutionary EDM tapping accessory!

The EDtapper adds CNC capabilities to your sinker EDM machine,
allowing you to tap a wide variety of holes. Just attach to machine
as you would an electrode with magnet or shank, affix electrode to
electrode holder, position appropriately, extend and fix base foot,
adjust horizontal movement scale, set the depth of sinking to 42mm
and operate. Complete setup takes just 5 minutes!

Features:
· Adds CNC capabilities to your sinker EDM machine.
· Takes just 5 minutes to set up and operate.
· Converts vertical movement to orbital movement.
· Forms the whole depth of the thread in a single orbital cycle.
· Eliminates need for interfering with machine's circuits--attach as

an electrode holder, and it's ready to operate.

· Maintains machine features of sinking and withdrawal.
· Controlled via the control panel of the machine.
· Designed so electrode withdrawal is made towards hole center,

not in direction from which it came (improves flushing).

· Flexible hose for spraying fluid right through the electrode when

making blind threads.

· Two positions for electrode attachment: orbital fixed angular for

threads, circlip slots, inverted cones and more, or orbital and
rotational about its axis for circular symmetrical shapes.

· Special attachment for easy electrode removal and replacement

without losing presets for threads (prevents cross-threading).
