MU-C: Entry-level Routing Machine

The Hoffmann MU-C 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 routing operation is started by pulling the main lever. 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 cutting 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.

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.
