Product Description
Overview:
Four motor production-duty, freestanding four-head dovetail routing machine with solid cast aluminum table and heavy steel frame.
Equipped with four router motors to rout two keyways into two workpieces at the same time.
Distance between keyways is operator adjustable from1 1/4" - 4". (32mm - 100mm)
For Dovetail Keys sizes W-0,W-1, W-2, W-3.
Highlights:
Large work surface is designed to be at a comfortable working height, the router motors are controlled by a contactor and a 4” dust collection port is located at the back for connection to a central dust collection system.
PP2-TAB -- a typical application is the production of mitered cabinet doors
Operation:
The keyway locations are adjusted by positioning the guided center fence plate on the machine table and by moving a hand-wheel to adjust the router bit spacing.
The keyway length (routing heights) is adjusted by setting one height-stop rods for all four router heads to the desired setting. 
PP2-TAB with four router motors with one height adjustment rod (yellow tape scale) on left.
Pressing the pneumatic foot pedal starts the machining cycle:
> Pneumatic clamps secure both work-pieces and motors are switched on
> Router heads advance until pre-set height is reached
> Router heads return to home position and motors are switched off
> Pneumatic clamps release work-pieces

Output is approx. 16 routing strokes per minute, which translates into 4 completely processed rectangular frames. These numbers include material handling, but obviously depend on routing depth, feed speed, material flow and operator performance as well. Flow control valves on the main pneumatic cylinder allow the operator to adjust the upward and downward feed rate independently, depending on the material being processed. A 4" diameter dust collection port in the back is used to connect a central dust collection system.
The supplied router bits are solid tungsten carbide, made to exacting specifications. Depending on the routing depth and the material to be routed, the useable cutter life is approx. 10,000 strokes, often times even more. Every machine is shipped with a tool kit and set-up jig, which allows a router bit change in only minutes.
