The
Hoffmann MU2-P 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
machine is equipped with a pneumatic foot switch to start
the routing process. Upon
depressing of the switch, the routing sequence is initiated:
-
pneumatic
clamp secures workpiece on machine table
-
router
head advances until the pre-set height position is
reached
-
router
head returns to base position
-
pneumatic
clamp releases work piece
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. Flow control valves on the main pneumatic
cylinder allow the operator to adjust the upward and downward
feed rate independently, depending on the material being
processed.
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.
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 tooling is also available.
