Features
The Hoffmann MU2 bench - top routing machine is equipped with a high speed router motor, located at the center of the machine.
Description
The Hoffmann MU2 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.
Pulling the main lever starts the routing operation. A hold down plate will be lowered onto the workpiece, pressing it on the table and holding it in place. Further pulling will lift the motor carriage up until the preset routing height is reached.
The motor is switched on automatically by pulling the lever, it is switched off again when the lever is returned to the home position.
Two springs in the lever mechanism counteract the pull down force, which ensures controlled movements throughout the routing process.
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.
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.
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.
