The Hoffmann PU2-TF is a routing machine equipped with two carbide router bits to rout two dovetail slots per miter. The router bits are installed in high speed Hoffmann brand router motors. 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 location of the dovetail slots for the Hoffmann Keys is adjusted by simply moving this fence plate.
The distance between the router bit centers is set at the factory to customer’s specifications, and can range from 2 9/16” - 4” = 65mm - 100mm. Larger spacing is available.
The machine is equipped with a pneumatic foot switch to start the routing process. Upon depressing the switch, the routing sequence is initiated:
pneumatic clamp secures workpiece on machine table
router heads advance until the pre-set height position is reached
router heads return to base position
pneumatic clamp releases work piece
Output is approx. 16 routing strokes per minute, which translates into 2 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 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.
