Hoffmann PU-2TL dovetail routing machine is a free standing
production unit for multi angle applications like handrails,
custom millwork, yacht interiors, store fixtures, displays,
etc. This model can be set to rout either vertically up and
down for all standard miters (a locking stop indicates the
0 degree mark), or it can be tilted up to 45 degrees forward
or back. Set at an angle, the router will travel up and away
from the operator if tilted back, and up and toward the operator
if tilted forward. The adjustment is made with a hand wheel
located at the front 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 or, in case of
butt and angle joints, with the included square stops.
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 miter 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.
A heavy steel table provides
a large work surface, the cabinet has a 4" diameter dust
collection port on its backside 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 cutters are also available.
