9940 Hoffmann MU3 PD Pneumatic Router with Digital Reader and W2 bit

More automated version of the MU3. One short stroke cylinder clamps the material the instant the foot pedal is pressed, while a second, larger cylinder moves the router carriage up and down. Operation is faster and more comfortable, and both hands can remain on the moulding during the routing cycle, useful when working with larger frames. Optional extension tables are available.

MU3PD includes a digital reader for quick and accurate set-up of routing cycles.

The Hoffmann Dovetail Router works differently - while a V Nail has to compress or displace timber, the Hoffmann Router removes timber to form a slot in each face of the mitre. Moulded double dovetail keys are then tapped into the slot for a right, permanent join.

This Hoffmann MU3 PD Pneumatic Router with Digital Reader is supplied with a W2 router bit, solid tungsten carbide with a life of around 10,000 strokes. W0 and W1 are sold separately. Hoffmanns requre a standard 13a power suppler and commercial grade vacuum cleaner for dust extraction. MU3P models require a compressed air supply.

MU3 P is a professional level, pneumatically controlled dovetail routing machine to rout a single dovetail keyway with each machining cycle. Heavy cast aluminium construction with large ergonomically shaped table surface, precision linear bearings and galvanised steel motor carriage with integrated fine adjustment.

Pressing the foot switch starts the machining cycle:

• Pneumatic clamp secures moulding on worktable and motor starts

• Router head advances until pre-set stop is reached

• Router head returns to park position and motor cuts

• Pneumatic clamp releases moulding

Max routing height: 95mm, Max moulding height: 150mm  Made in Germany

How does a Hoffmann Router work?

- Set the router depth using the digital reader on the MU3PD.

- Position the slot - lay a mitred piece on the bed and line up the slot location with the indicator on the machine. Slide up and lock the centre fence plate. On the MU3PD the position is shown on the digital reader for quick and repeatable setup. 

- Place the mitred piece to be routed on the left side of the bed with the rebate facing away.

- To start the machining cycle, pull the foot switch.

- Padded hold-down plate / pneumatic clamp secures moulding and motor is switched on. Continued pulling / foot pressure advances the router head until pre-set height is reached.

- Release the lever to return the router to its home position, shut off the motor and release the moulding. Pneumatic models return automatically. 

- Move the mitred piece to the right side of the bed to rout the other end. Repeat for all four mitred pieces.

- Assemble the frame by placing the first two pieces fast down, inserting the key and tapping it home with a soft face hammer. Repeat to complete the frame.
