High-end residential cabinets and trim are also a part of the
total production at John Murphy Millwork.
The Erie, Colo., company is also known for its complex and
curved casework, reception desks and moulding.
to their production process. It is used for
boring of most panel parts for cabinet line
case sides, drawer sides and case floors.
“Previously, the work was done on our
Biesse Rover 30 flat table,” John Murphy
says. “The Hirzt machine solved a couple
of problems for us. It reduced our material
handling time. We can process a part in
one minute including load and unload. It
took far longer on the Rover.
“The Rover process involved taking
one part, stepping on to one of the safety
zones, squaring and vacuuming the part,
waiting for the machine to clear the opposite field, and squaring and vacuuming
the next part in the opposite field.”
The Hirtz Livra machine is also
equipped with a laser measuring system
that measures the part length and
adjusts construction holes to match,
providing good-fitting parts. It is a big
savings in assembly and improved the
quality. Another plus is that it takes very
little to train someone to run the Livra.
An unexpected benefit was the dramatic
savings in electrical usage. Murphy’s
electric bill dropped $300 per month.
“Now we can utilize the Rover to do
what it does best, complicated routing,
without delaying box part production,”
John Murphy says.
The addition of the Hirzt machine also
has sped up the entire case construction line.
“The speed of the Hirzt Livra puts
pressure on the other stations to keep
up,” John Murphy says. “It has really
changed how our shop runs.”
There are two different flow patterns
in the shop — panel processing and
solid wood processing. Flow through the
shop is controlled by labels created by
Pattern Systems Product Planner. The
label describes the part, size, operations
required, and its location by cabinet,
room number and project number.
Machines in the panel processing
line in order of flow are: Selco EB110
panel saw, Akron 440 edgebander, Hirzt
Livra feedthrough point-to-point, Omal
dowel inserter, Biesse Rover 30 flat table
point-to-point, and Murphy’s first point
to point, the Alberti A11.
Assembly and finishing
After the machining process parts go
