they’d increased the cutting speed to 450 sfm, the
feedrate to 0.5 mm/rev (0.02 ipr), and the depth of
cut to 5 mm (0.2 in.). The result? A twenty-minute
reduction in cycle time, and a complete part using
only one corner of the insert.
“We have been very happy with the results,”
says Lachance. “We not only reduced the cycle
time substantially, but have also developed a more
stable process. The only thing I would add to
those attempting similar results is that you need a
very strong machine to handle cutting parameters
such as this, a task that is well within the Mazak’s
This is but one example of the continuous
improvements common at OSI Précision. Another
is the recent acquisition of a six axis, seven metre
( 23 ft.), robotically loaded vertical machining
centre from Spanish builder Correa S.A. that's
sold by Elliott Matsuura in Canada. Michaud says
it's helping the company reduce setup times and
attract new business (and yes, it’s equipped with
Sandvik Coromant tooling). “There aren’t too
many companies with a machine this large or this
capable,” he says. “With the Correa, we’ve become
very active with many different industries–there is
a big demand for very large, complex parts, which
was the main reason we invested in the machine.
Since its installation in August 2016, it has become
quite busy, and is now bringing us a nice return.
And the ironic part is, we didn’t have any work for
it when it was ordered.” SMT

twelve years,” he says. “They are a very good customer, and do some
challenging work. When Denis told me about the wheel parts–a 4340
steel forging that was heat-treated to 38 HRC, and required substantial
amounts of metal removal–I knew right away what to use.”
Boutin brought in Sandvik Coromant’s GC4305, a grade designed
specifically for high-volume steel turning in the automotive sector, but
equally suited for the railcar wheel. He worked with Lachance and his
team to fine-tune the cutting parameters. By the time they were done,
