As a leading CNC machine shop
in PA, John Prosock Machine, Inc. has to be able
to machine any material a customer wants. That's
why we offer a variety of materials from aluminum,
to brass, to
plastic,
to steel, to
copper, and
more. However, different materials involve different
precision CNC machining concerns. John Prosock
Machine takes the mechanical properties of each
material from standard to exotic into consideration
prior to precision machining operations to avoid
complications and produce accurate results for
customers in New Jersey, New York, Pennsylvania,
Maryland, Delaware, and Wisconsin.
How
a Materials Thermal Expansion
Affects Precision Machining
Errors in thermal expansion play a substantial
role in determining part accuracy. For this reason,
international standards organizations have adopted
68°F or 20°C as the standard temperature
for the measurement of length. Since the coefficient
of thermal expansion in each of the materials
we machine varies, compensation methods must be
implemented. In order to adjust for length, expert
machinists at John Prosock Machine compare the
change in length to the coefficient of thermal
expansion and the standard temperature. With this
information, part accuracy, regardless of material,
is significantly improved.
Different
Inserts for Different Materials
While materials, such as hardened steel construct
superior indestructible parts, they can be challenging
to machine. Yet recent advancements in indexible
inserts make it possible to machine just about
anything. John Prosock Machine Inc. utilizes coated
carbide, cermet, cubic boron nitride, and polycrystalline
diamond inserts with unique geometries and coatings
that can resist wear even under extreme shock
and heat conditions.
Trends in the precision machining
industry dictate trends in the manufacturing of
cutting tools. As manufacturers continue to experiment
with new materials, cutting toolmakers strive
to design inserts that maximize part precision
and CNC machining company production. John Prosock
Machine stays up-to-date on all recent advancements
in the cutting tools and inserts. We are constantly
evaluating new inserts so we can provide our customers
with a wider range of material options.
Tool holders and Cutting Fluid in
Precision Machining
John Prosock Machine Inc.’s precision machining
only benefits from optimal inserts when stable
tool holders and the right cutting fluid is used
for the specific type of material being machined.
We routinely inspect tool holders in each of our
CNC machines to make sure that inserts are changing
as quickly and accurately as possible. Hard-to-machine
materials and high temperature alloys require
specific cutting fluid formulations and thermal
expansion characteristics can be altered with
the right coolant. At John Prosock Machine, we
spare no expense for high-quality cutting fluids
for precision machining of every material type.
Manufacturers are always looking
for the next best material for their product or
system. And John Prosock Machine, Inc. is proud
to offer a range of materials to choose from including,
but not limited to aluminum, brass, copper, plastic,
and steel. We compensate for every material’s
coefficient of thermal expansion and ensure that
the right tool, tool holder, and cutting fluid
will be used so customers have the freedom to
select the material that will work best for their
product or system.
