As a
manufacturer, you come to a point when you realize
you need to grow your business with
capital equipment. With new technological advances taking place every day, just
staying up to date on the latest and greatest can become a daunting task. Just
the thought of the financial, technical and logistic burdens sends you into a
whirlwind of mixed emotions and fears.
So, what happens inside the minds of
a machine tool builder when they come to that point? Most people would say
something like the following.
“They’re a machine tool builder; all
they have to do is use their machines to build more machines, right?”
Wrong. Just like any other
manufacturer, a machine builder has to take a step back and look at the big
picture. They need to make decisions that will allow them to achieve their goals
efficiently, productively and with the best ROI. Which is where Haas Automation
found itself in March 2004. Haas, as everyone knows, manufactures CNC vertical
machining centers, horizontal machining centers, CNC turning centers, rotary
tables, and more, for a worldwide market of job shops and manufacturers.
Goal: Ship 1000 Machines a Month
The machine tool orders coming into
Haas’ factory in Oxnard, CA, were increasing every day. To meet the demands from
their customers, Haas set a goal of building 1000 machines a month. However,
with this new goal in place, it became apparent they would need to add more
capital equipment and automation. Bob Murray, Haas general manager, was in
charge of spearheading the project.
“Our primary objective was to expand
our machining capacity and to reduce cycle times and costs,” he says.
Haas wanted to do this without
expanding its facilty.
Out for Bid
To get going, Haas sought out
different machine tool builders and distributors to make a bid on the new
automated equipment it needed.
Ellison Technologies was one of those distributors. Ellison Technologies, Santa
Fe Springs, CA, is a locally owned and operated subsidiary of the Ellison
Technologies Group of Companies, a large, North American integrator of automated
industrial and capital equipment. Ellison includes a staff of consultants,
engineers, sales, service, and training professionals to support the needs of
manufacturers throughout California and Nevada.
Fraser Marshall, Ellison director of
operations, put together a business case based on Haas’ requests.
“In our booth at Westec 2004, we
showcased a Mori Seiki horizontal machining center with a linear pallet pool
(LPP) system,” says Marshall. “With the goals that Haas needed to achieve, only
lights-out manufacturing could accomplish those results, and this type of
flexible manufacturing system would be our case.”
Evaluating Options and Configurations
It was a 5-month decision process.
Ellison put in many long hours assessing the project and developing the
solutions that would meet and even exceed Haas’ expectations.
“We went straight to the source,”
says Marshall, “We made a trip to Japan to fully understand the system, spoke to
the engineers, worked out all the logistics so that we would be able to better
manage the project.”
In the end, two systems were needed. The first system would include five Mori
Seiki NH6300 horizontal machining centers with 138 pallet stands, six loading
stations and an integrated wash station—and only five weeks to install.
The second system would follow with
two Mori Seiki NH8000 horizontal machining centers and 44 pallet stands —with
only three weeks to install.
“The final decision was not easy,” explains Murray. “A deciding factor was our
relationship with both Mori and Ellison. We enjoy an excellent working
relationship with Ellison. They have proven themselves over many years with
consistent quality service on a number of projects.”
Determining how to pay for the new capital equipment can often be a deal
breaker. The good news is it doesn’t have to be. With the new advances in
machine technology, often times the equipment’s ROI can be achieved in as few as
two years. Many options are available for manufacturers today, including
differing types of loans and leases for financing the equipment.
Murray adds, “These cells have
allowed us to bring some contracted work back into the factory.”
Making Space
For most manufacturers available
space in a facility is hard to come by, and gets even harder the older the
business. Haas needed to add the maximum number of machines and pallets in the
square footage it had available.
“It seems like there is never enough
space,” says Murray, “but this project was important, and space was made
available.”
With a March completion of Haas
Automation’s latest expansion, building 4, the Oxnard, CA, facility, a one
million square-feet of manufacturing and warehouse operation, was chosen as the
site for the project.
Lights Out Operation
Another major factor to consider
during the buying process is labor. How do you add to your shop floor but not
add to your labor costs?
With the LPP system, Haas’ approach
was to achieve 16 hours of unattended operation. The key to making that approach
possible is to be able to predict tool life. If a tool fails during unattended
operation, cutting can stop. If you’re not cutting chips, you’re not making
money.
Since Ellison doesn’t employ
psychics, the distributor enlisted Mori Seiki’s CAPPS-TMS (tool-management and
scheduling-software). With the software and a Parlec tool pre-setter, Haas’ day
shift would be able to run a systems check on the cell’s tool-life. By running
this check, they would know what needed to be replaced before lights-out.
“People expected a great deal in the
way of tool management and job scheduling from the cell controller, and all
expectations were met,” says Murray.
In order to keep everything on
schedule, Ellison held weekly project management meetings—a critical factor for
an installation of this magnitude.
“Ellison met their schedule for
delivery and installation. We are very satisfied. Most of our goals have been
achieved,” concludes Murray.
