Hoffmann MU3 - shown with optional table extensions
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.
Motor fine adjustment and quick-release lever
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 motor is switched on
> Continued pulling advances the router head until pre-set height is reached
> Releasing the lever returns the motor to its home position and shuts off motor
> Padded hold-down plate releases work-piece
With the operator controlling the speed of all machine movements, output is greatly depended 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 exacting 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.
