New
oil paves way for better performance at Spectator

In
the newspaper business, deadlines are a way of life.
That’s
as true for the press operator as it is for the reporter working on a
late-breaking story.
Any
glitch in equipment operation can cause unnecessary delays and cost time and
money - not to mention increased anxiety for all involved, from the publisher to
the convenience store owner selling the newspaper.
So
when the Hamilton (Ontario) Spectator began running into production problems in
the late 1990s, it knew it needed a quick solution.
The
Spectator (daily, 260,000) prints more than 500,000 copies per day on Goss Metro
presses it’s used since the late 1970s.
Up
until 1998, said Maintenance Supervisor George Tedesco, the presses performed
flawlessly. But, he said, “We started having problems with sticking
eccentrics,” he said. “We had to consistently get in there and give them a
little bump to get them going.”
Caused
delays
For
the Spectator, this little bump was causing delays and becoming increasingly
inconvenient, wasting valuable time and money.
“It
was through a Goss Metro users convention that my boss found out from other
users that they were having the same problems,” Tedesco said. “Eventually,
we figured out it was caused by the oil.”
An
investigation revealed that the machine tool and way oil recommended by the
manufacturer when the press was installed had been reformulated some years
later, much to the surprise of many maintenance managers.
“They
had reformulated the oil and in the process they took away the stickiness of the
oil - the tackifier,” Tedesco said. “The clingability of the oil wasn’t
there anymore. But we were never notified that the oil had been reformulated and
we kept using the same oil and ran into problems.”
Through
colleagues in the newspaper industry, the Hamilton Spectator’s maintenance
staff learned about another brand of machine tool and way oil, Accuflo SS 68,
manufactured by Petro-Canada.
Problem
ends
Since
switching lubricants, Tedesco said his newspaper has eliminated the problem and
the presses have been running far more efficiently.
“It’s
been about two years since we’ve changed the oil and the problem has
disappeared,” Tedesco said. “The performance of the press has greatly
improved since we started using the product.
“The
(oil) meets the specs Goss recommended when the presses were first installed,”
he said, adding that tests indicate the oil is clinging to the metal, as it
should.
“You
can see it when you put the oil between your fingers and pull them apart. With
the (new oil) you’ll see several strands hanging back and forth.”
Resists
pressure
Petro-Canada
formulated the oil to resist pressure, moisture and coolants as it eliminates
metal-to-metal contact. The result: smoother press operation, reduced wear and
extended machine life, according to the company.
The
manufacturer recommends the oil to lubricate press’ units, folders, angle bars
and horizontal gear boxes. The oil meets Goss’ requirements for Cosmo, Metro,
Metroliner, Headliner, Colorliner and Metrocolor presses.
Tedesco
said that switching lubricants has helped the Spectator cut costs and improve
press performance.
“Wear
protection is key,” he said. “That’s going to save you a lot of
heartache.”
Tedesco
said avoiding press downtime is another important consideration.
Costly
downtime
“You
can’t afford to have the press down, particularly if it’s a unit in the
middle of your line,” he said. “It’s hard to work around that type of
issue. You just can’t put a figure on what it would cost to initiate that type
of repair. It would be way too costly. The downtime alone is going to kill
you.”
Finding
the right lubrication also allowed the Spectator’s maintenance staff to focus
its efforts on regular maintenance.
“You’re
saving time on production runs and you’re saving time on maintenance trying to
track down these phantom problems,” Tedesco said. “The machinery has got to
work properly. Otherwise, it’s just not what you paid for.”
