The thermal energy method for
deburring and deflashing parts isn't
new. It's how Basin Precision Machining applies it to a high mix of
parts that sets the company apart
from its competition.
While its competitors use drills,
files and knives to remove sharp edges (burrs) generated by the machining process, Basin Precision utilizes
a new thermal energy method developed by Germany-based manufacturer ATL. ATL's iTEM series machines
provide precise metering and pressure control that allows Basin Precision to seamlessly switch between
larger than 200-part numbers with no
"Our employees don't use knives
to deburr parts anymore," Basin Precision CEO Erik Anderson says. "We
use thermal energy to remove burrs.
The parts are placed in a chamber,
which is pressurized with a mixture
of methane and oxygen. We then ignite the mixture. The resulting flash
generates nearly 6,000F degrees for
about 20 milliseconds. The heat is absorbed by the thin edges on the part,
and those thin edges flash oxidize, removing burrs."
It's absolutely critical that burrs
are removed, a process that traditionally requires manual dexterity and
extreme attention to detail, but ultimately is high risk due to its manual
nature, Anderson says. "You can bring
a million dollar machine to its knees
with one loose burr," he adds.
