The Hoffmann PP2 dovetail routing machine is a free standing production unit. This model is equipped with two high-speed router motors, to process two parts simultaneously. The supplied 45 degree fence plate, which is guided in a keyway in the machine table, is used to accurately position the material on the table. The locations of the dovetail slots for the Hoffmann Keys are adjusted by simply moving this fence plate.
The machine is equipped with a pneumatic foot pedal. Upon pressing the foot pedal, the routing sequence is initiated:
pneumatic clamps secures workpieces on machine table
router heads advance until the pre-set height position is reached
router heads return to base position
pneumatic clamps releases workpieces
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 heavy-duty cast aluminum table provides a large work surface. The steel cabinet has a 4" diameter dust collection port on its backside for dust free operation.
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. Every machine is shipped with a tool kit and set-up jig, which allows a router bit change in only minutes. Diamond cutters are also available.
