Engineering & Design
Acme's team of engineers is highly trained and knowledgeable in marine propulsion
and can assist or fully size and design propellers for practically any application
or requirement. Thorough integration of engineering with manufacturing ensures
feasibility and optimization from one stage of propeller development to the
next. It also means that every Acme prop is manufactured true to the design
intent. So even at the moment when a potential propeller is only a partially
constructed image in the mind of an Acme engineer, serious consideration is
already being given to the capabilities of the manufacturing process.
Upon completion of the designs and programs, Acme then builds patterns,
pours castings, and machines and balances the finished propellers. The fully
CNC'd propellers are then entirely ready to be installed in their intended
capacity — no adjustments or fine-tuning are required,
because any minor adjustments that might be desired can be made in the numerical data of the
machine programs and thus translated to the finished parts. Note that there is
virtually no outsourcing of operations directly related to the finished product.
Foundry – White Cloud, Michigan, USA
Decades of experience producing high quality non-ferrous castings to
military specifications has provided a manufacturing foundation ideally suited
for ACME propeller castings. Our experience has translated into the ability
to handle a wide variety of materials and to deal with the critical aspects of
material testing and traceability. Only the finest grades of metal, produced
to military specifications, are used in the manufacturing of ACME propellers.
Proprietary methods of mold building and material handling ensure ACME props
are of the highest quality.
Since the CNC'd surfaces on the propellers cannot be welded without
significant alteration to the surface finish, it is important for the castings
to be free of defects. In order to maintain the outstanding level of accuracy
and consistency in production, a fully CNC’d ACME prop does not allow
for the traditional methods of grinding, hammering and welding to obtain the
prop's finished specifications. Therefore, it is imperative that the process
begins with sound castings of superlative integrity.
Acme Propellers are produced on a foundation of more than seven decades of
machining and manufacturing experience. Highly qualified personnel, state-of-the-art
machinery, skillfully refined methods, and strict process controls are some of
the key contributors to the superior quality and consistency of Acme Propellers.
To further ensure product excellence, expedient delivery, and few-to-zero
defects and returns, Acme utilizes proven quality control systems and relentlessly
strives for continuous improvement at every level of product development.
