» Hoffmann Dovetail Routing Machine, model MU2-P, ready for operation, with air regulator - filter - lubricator assembly installed, with W-2 carbide router bit installed, with standard 45 degree fence plate and square stop, including toolkit and manual.

The Hoffmann MU2-P bench-top routing machine is equipped with a high speed router motor, located at the center 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 slots for the Hoffmann Keys is adjusted by simply moving this fence plate. Once set, the plate is locked in place and the routing sequence can begin.

The machine is equipped with a pneumatic foot switch to start the routing process. Upon depressing of the switch, 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 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.
On its backside, the large heavy-duty cast aluminum machine base has a 1 3/4" diameter dust collection port to connect a shop vacuum 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 tooling is also available.
