Hoffmann MU3 Manual Dovetail Routing Machine

Hoffmann MU-3 Machine Overview:

Professional level, manually operated dovetail routing machine to rout a single dovetail keyway with each machining cycle.

Heavy cast aluminum construction with large, ergonomically shaped table surface, precision linear bearings, galvanized steel motor carriage with integrated motor fine adjustment.

For Dovetail Key sizes W-0, W-1, W-2, W-3 (W-4 with optional larger motor)

Highlights:

This manually operated dovetail routing machine does not require a compressed air supply. It can be equipped with the optional left and right-hand extension tables, a helpful feature especially when processing longer parts.

Operation:

The keyway location is adjusted by positioning the guided center fence plate on the machine table;

the keyway length (routing height) is adjusted by setting a height-stop rod to the desired setting.

Routing parts for a miter joint

Pulling the main lever downward starts the machining cycle:

> Padded hold-down plate secures work-piece and the motor is switched on

> Continued pulling advances the router head until the pre-set height is reached

> Releasing the lever returns the motor to its home position and shuts off the motor

> Padded hold-down plate releases work-piece

With the operator controlling the speed of all machine movements, the output is greatly dependent on material flow, handling, and operator performance.

On its backside, the large heavy-duty cast aluminum machine base has a 2" diameter dust collection port to connect a shop vacuum for dust-free operation.

The supplied router bit is solid tungsten carbide, made to exact specifications. Depending on the routing depth and the material to be routed, the useable cutter life is approx. 10,000 strokes, often times even more. Every machine is shipped with a tool kit and set-up jig, which allows a router bit change in only minutes.
