the arena in which Action EDM & Tool, Concord, NC, is
involved is not transportation, the ability to triple parts
inspection speed has changed the way the company works. Recent
instrument acquisitions have helped Action EDM substantially
speed and simplify its critically important 100% parts product
inspection to the point where the company can approach zero-defects
for its customers.

EDM's highest priorities are product repeatability and accumulated
accuracy. With customers whose specifications are extremely
tight, "we have made major advances in achieving these
objectives quite recently," says David Fry, president
of the four-year-old company.
"At a time
when new CNC and higher tech inspection equipment make our
need for accuracy an increasingly demanding challenge, this
rate of growth is difficult to sustain unless we take innovative
approaches to instrumentation for in-process and final inspection,
which helps us develop new ways to meet the needs of our customers
for even shorter lead times at reduced costs. We can't afford
to think conventionally about these things," he says.
procedure typifies how the company has improved its operations,
says Roger Greeley, QA manager. "Formerly we relied on
gage block setups and digital height towers for our inch-metric
accuracy assessments. Since the month of March, when we purchased
two Fowler/Sylvac Z-Cal Height Gages--one
0.6´´, the other a 0-12´´ model--we
can zero off the table directly in these inspection operations.
For every hour we used to spend in inspection with the block
and towers, we now spend only 15 min with this high precision
the company tripled the speed of inspection, says Mr Greely.
In addition, the company's versatility has increased, because
it has eliminated the errors of human touch and has added
the ability to check parallelisms, sizes, and location.
the instrument is especially designed for measuring fragile
and sensitive parts. Its probe speed is proportional to finger
pressure as it measures heights, depths, slots, internal and
external diameters, the distance between centers and position--all
with an accuracy of 2µ. Mr Fry adds that the deluxe
probe set his company uses permits location inspections of
threaded holes. Also, probes can be changed and calibrated
in about 1 min. The gage is light in weight (9.4-11.66 lb,
respectively, for the two models) and compact in size (14´´
and 20´´) and sold with a five-year warranty.
