The Hoffmann PU2-TL dovetail routing machine is a free standing production unit for multi angle applications like handrails, custom millwork, yacht interiors, store fixtures, displays, etc. This model can be set to rout either vertically up and down for all standard miters (a locking stop indicates the 0 degree mark), or it can be tilted up to 45 degrees forward or back. Set at an angle, the router will travel up and away from the operator if tilted back, and up and toward the operator if tilted forward. The adjustment is made with a hand wheel located at the front of the machine. 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 slot for the Hoffmann Dovetail Key is adjusted by simply moving this fence plate or, in case of butt and angle joints, with the included square stops.
The machine is equipped with a pneumatic foot pedal. Upon pressing the foot pedal, the routing sequence is initiated:
pneumatic clamp secures workpiece on machine table
router head advances until the pre-set height position is reached
router head returns to base position
pneumatic clamp releases work piece
Output is approx. 16 routing strokes per minute, which translates into 2 completely processed rectangular miter 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 steel table provides a large work surface. The cabinet has a 4″ diameter dust collection port on its backside for dust free operation.
The supplied router bit is 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.
