    Core Competencies

    Engineering Services

    We are a team of experienced engineers focused on assisting customers to meet and overcome challenges ranging from collaborating on design for new products and manufacturing processes, staffing, reverse engineering for legacy and other critical requirements.

    We aim to create high performance solutions that are maintainable, sustainable, and functional.

    Flow Control

    Couplers, Fittings, Fuel Filters and Valves

    Collaborating with customers to design and manufacture proprietary or custom flow control devices (couplers, fittings, fuel filters, and valves) is a process in which AMG is uniquely qualified to perform. Lead by our experienced engineering team, we have manufactured innovative, efficient, and reliable products for over thirty years.

    AMG’s entire product line of flow control devices is manufactured and tested in our Indianapolis facility.

    CNC Machining Capabilities

    AMG Engineering & Machining, Incorporated, is a AS9100D, IATF 16949, and ISO9001:2015 certified machining and manufacturing operation. Our focus comprises medium diameter (.050″ to 28″ turned and 2″ to 40″) milled parts with lengths up to 70″. Our effectiveness at machining diverse materials such as aluminum, cast iron, stainless steel, alloys steels, nickel super alloys (Inconel), and titanium, is driven by an experienced team and an extensive array of late-model, top of the line CNC machine tools. Our equipment delivers high throughput, accuracy, and reliability while simultaneously being manufactured and serviced by world class leaders in CNC machine tools.

    AMG Engineering provides turnkey service managing the entire project from quoting to final product delivery. Our lot size range spans the machining of prototypes to the production of quantities in the hundreds of thousands. As a womb to tomb supplier, AMG provides product from inception to retirement alleviating one less worry for our customers.

    As AMG is also registered with the FDA to provide contract machining for medical applications. We are qualified to support organizations with special and disciplined quality and production systems to ensure best practices and world class quality. Striving to achieve complete customer satisfaction in every aspect of business to build solid long term relationships is always the goal of our team.

    CNC Horizontal & Vertical Milling

    AMG Engineering’s customers are supported by highly precise CNC milling services using the latest 5-Axis technology available. To ensure maximum productivity, the machinery is equipped with auto gauging, tool breakage detection, high pressure coolant, and tool management software.

    CNC Horizontal & Vertical Turning

    Utilizing horizontal and vertical turning technology, AMG’s lathe department can machine diameters from .125” to 62”. Our array of machinery for these applications provides customers with one stop shopping for components of this size.


    This process is used by AMG to improve the geometry of a part; by readjusting the alignment of features such as holes or bores, enabling us to produce finer surface finishes.

    Metal Sawing

    Representing the start of the production cycle for many of the parts produced at our plant, the saws have preset feed rates, part feeding capability, and part clamping features which allow them to operate independently.


    AMG utilizes this machining process to achieve super-flat surfaces and incredibly tight tolerances on parts that require accuracy at the microscopic level.

    Wire EDM

    Highly accurate with great surface finishes are characteristics of AMG’s wire EDM work. Our team consistently produces sub-micron precision and outstanding surface finishes for complex part geometries.

    Ultrasonic Cleaning

    Ultrasonic cleaning is the norm at AMG Engineering & Machining, Inc. This exclusive cleaning method utilizes high frequency sound waves to generate cavitation in the liquid.

    Millipore (Cleanliness) Testing

    In today’s high precision manufacturing environments, the supply of ultra-clean components is often paramount to performance and reliability of finished goods. AMG’s technical team is fully capable of meeting most cleanliness requirements.

    Furnace Brazing

    This process is utilized by AMG to join metal components using a dissimilar lower filler metal; it allows engineers to connect simple or complex designs of one or multi-joint assemblies.

    Thread Locking

    Thread locking is a process of applying special compounds to a substrate such as bolts or nuts. These compounds are applied and activated during the assembly process and cures forming a polymer that both locks and seals.

    Sub-Assembly and Kitting

    First, become proficient at building single components. Next, begin building simple sub-assemblies and then more complex ones.

    This was an element of AMG’s growth strategy from the company’s inception in 1989 which ultimately led to the following goals being routinely achieved for our customers:

    • Building sub-assemblies comprised of components machined in our plant

    • Reducing customer total costs

    • Shortening supply chains while simultaneously adding value
