Sometimes the hardest part of an industrial repair isn't making the component.

It's figuring out exactly what needs to be made.

Drawings disappear. OEM parts become obsolete. Equipment gets modified over decades of service. Components wear so severely that their original dimensions are no longer obvious.

And sometimes the only information available is the damaged part sitting on the shop floor.

Electric Machine & Fab provides engineering, component analysis, and reverse engineering capabilities to help customers solve difficult industrial repair and replacement challenges.

More importantly, our engineering capabilities are backed by real industrial manufacturing resources.

Once a solution is developed, EMF can bring in industrial machining, CNC machining, heavy fabrication, welding, large-format plate cutting, equipment rebuilding, and replacement part manufacturing to help turn that solution into a finished component.

Engineering Connected to the Shop Floor

Engineering is most valuable when it leads to a practical solution.

At EMF, engineering and analysis don't exist in isolation from the people actually repairing, machining, welding, and fabricating industrial equipment.

Our team can evaluate a component while considering how it may ultimately need to be:

• Machined
• Fabricated
• Welded
• Rebuilt
• Modified
• Reinforced
• Reproduced
• Installed
• Returned to service

That connection between analysis and manufacturing gives EMF the ability to approach problems from both sides.

We don't just ask what the component was.

We ask what it needs to do—and how we're going to make it.

Industrial Reverse Engineering

Reverse engineering can provide a path forward when original drawings, specifications, or replacement components are unavailable.

An existing component can often provide valuable information about its geometry, dimensions, interfaces, and function.

Depending on the project and condition of the part, EMF can evaluate existing components and available technical information to help develop the information necessary for repair or reproduction.

Reverse engineering may be useful for:

• Obsolete industrial components
• Discontinued OEM parts
• Damaged equipment components
• Difficult-to-source replacement parts
• Older machinery
• Modified equipment
• Mining equipment components
• Custom machinery
• One-off industrial components
• Components with incomplete documentation

Once the requirements are established, the project can move directly into EMF's machining, fabrication, or rebuilding operations.

When the Original Drawings Are Gone

Industrial equipment can remain productive for decades.

The paperwork doesn't always survive with it.

Drawings may have been lost.

The original manufacturer may no longer exist.

Equipment may have changed ownership several times.

Components may have been modified in the field.

In some cases, no usable documentation exists at all.

That doesn't automatically make the equipment impossible to repair.

EMF can work with the existing component, available measurements, customer information, equipment specifications, drawings, samples, and other technical information to help establish a practical path forward.

Sometimes the worn part itself becomes the starting point.

Obsolete & Discontinued Replacement Parts

A productive piece of equipment shouldn't necessarily be retired because one part is no longer available.

Yet that's exactly the situation many industrial facilities eventually face.

OEM components can become:

• Obsolete
• Discontinued
• Difficult to source
• Excessively expensive
• Subject to long lead times
• Available only as part of a larger assembly

Reverse engineering combined with custom manufacturing can provide another option.

When appropriate, EMF can evaluate an existing component and determine whether a replacement can be developed using our machining, fabrication, welding, and plate-processing capabilities.

Component Analysis

Before deciding how to repair or reproduce a component, it's important to understand what you're dealing with.

Industrial component analysis can help establish the information required to make informed decisions about the next step.

Depending on the project, this may involve evaluating:

• Component geometry
• Critical dimensions
• Mating features
• Mechanical interfaces
• Wear areas
• Damage
• Existing modifications
• Mounting requirements
• Functional relationships
• Repair requirements
• Manufacturing considerations

The objective is to gather enough useful information to determine whether the component should be repaired, rebuilt, modified, or reproduced.

Engineering Support for Equipment Repair

Not every damaged component needs to be duplicated exactly.

Sometimes the better solution is to repair what already exists.

EMF's engineering and analysis capabilities can support larger repair projects by helping determine how worn or damaged components can be restored.

That work can connect directly with our capabilities in:

• Industrial machining
• Heavy welding
• Structural repair
• Fabrication
• Equipment rebuilding
• Replacement part manufacturing
• Component modification

Instead of treating engineering as a separate service, EMF can use it as part of the overall repair process.

From Reverse Engineering to CNC Machining

Once a component has been evaluated and the required dimensions are established, EMF can move directly into manufacturing.

Our industrial machining and CNC machining capabilities allow us to produce custom replacement components for demanding applications.

Depending on the project, machining can support:

• Shafts
• Pins
• Bushings
• Housings
• Mounting components
• Mechanical interfaces
• Replacement parts
• Custom equipment components
• Repair components
• Fabricated-and-machined assemblies

That creates a direct path from an existing worn component to a newly manufactured replacement.

From Engineering to Heavy Fabrication

Some industrial components aren't machined from a solid piece of material.

They're fabricated.

A reverse-engineered component may require heavy steel plate, welded sections, structural assemblies, machined features, or a combination of several manufacturing processes.

EMF's heavy industrial fabrication capabilities allow our team to turn engineering information into substantial steel components and assemblies.

Once fabricated, those components can move into machining where precision features are required.

Explore Industrial Fabrication & Welding →

Large-Format CNC Plate Cutting

Large industrial components often begin with large steel plate.

At EMF's Sidney, Kentucky facility, our large-format Messer CNC cutting system features a 10-foot by 30-foot cutting table.

For appropriate materials and applications, EMF can process heavy plate in the 8- to 10-inch thickness range.

This capability can support reverse-engineered and custom components requiring substantial steel sections.

A component can move from engineering information to CNC plate cutting, fabrication, welding, machining, assembly, and finishing within Electric Machine & Fab.

Reverse Engineering for Mining Equipment

Mining equipment is frequently kept in productive service for many years.

That creates unique repair challenges.

Components may be heavily worn.

Original parts may no longer be available.

Machinery may have been modified over its service life.

Documentation may be incomplete.

EMF's experience with underground and surface mining equipment allows our engineering and manufacturing capabilities to work directly alongside teams familiar with the equipment and the environment in which it operates.

Reverse engineering can support projects involving:

• Longwall mining components
• Underground mining equipment
• Surface mining equipment
• Heavy equipment components
• Material handling equipment
• Structural assemblies
• Wear components
• Shafts and pins
• Custom fabricated components
• Obsolete mining equipment parts

Once the solution is established, EMF can provide the machining, fabrication, welding, and rebuilding capabilities needed to carry the project forward.

Engineering Support for Heavy Equipment Rebuilding

Heavy equipment components don't always wear evenly.

Years of abrasion, impact, loading, and previous repairs can leave a component substantially different from its original condition.

Engineering and analysis can help determine how the remaining component relates to the dimensions and features required for proper operation.

From there, EMF can combine structural rebuilding, material replacement, machining, fabrication, and replacement component manufacturing to restore the equipment where practical.

Explore Heavy Equipment & Component Rebuilding →

Engineering for Equipment Retrofitting & Modernization

Reverse engineering isn't only useful for reproducing old parts.

It can also help make old equipment work with new components.

A modern replacement may have different mounting dimensions, shaft arrangements, interfaces, or structural requirements.

Rather than reproducing an obsolete component exactly, it may make more sense to modify the existing equipment.

EMF can combine engineering, machining, fabrication, and electromechanical capabilities to support industrial equipment retrofitting and modernization projects.

Repair It or Reproduce It?

One of the most important questions in industrial repair is also one of the simplest:

Do we really need to make a new one?

Sometimes the answer is yes.

Other times, an existing component can be restored through machining, welding, resurfacing, reinforcement, or partial reconstruction.

Because EMF provides both repair and manufacturing capabilities, our team can evaluate the problem from multiple directions.

The solution may involve:

Repairing the original.

Rebuilding the original.

Manufacturing a replacement.

Modifying the equipment.

Or combining several of those approaches.

From Worn Component to Finished Replacement

A reverse-engineering project can move through an entire manufacturing process within EMF:

Existing Component → Evaluation → Measurements & Analysis → Manufacturing Plan → Material Processing → Machining/Fabrication → Fit-Up → Finishing

For complex fabricated components, the process may include both heavy welding and precision machining.

That integration helps turn reverse engineering into something practical:

A finished part ready to solve the problem.

Replacement Part Manufacturing

Once the component requirements are established, EMF has multiple ways to manufacture the replacement.

Depending on the project, our capabilities can include:

• CNC machining
• Conventional industrial machining
• Large-format CNC plate cutting
• Heavy steel fabrication
• Industrial welding
• Component assembly
• Equipment rebuilding
• Industrial finishing

This allows us to manufacture everything from individual machined components to substantial fabricated industrial assemblies.

Engineering & Analysis Across Heavy Industry

EMF's engineering and reverse engineering capabilities support more than one industry.

We work with problems involving equipment used throughout:

• Mining
• Industrial Manufacturing
• Processing Facilities
• Utilities & Power Generation
• Heavy Construction & Earthmoving
• Material Handling
• Municipal & Infrastructure
• Aggregate & Material Processing
• Heavy Industrial Operations

The equipment may be different.

The challenge is often remarkably similar:

Something critical is worn, broken, obsolete, or unavailable—and somebody has to figure out how to solve it.

Two Facilities. One Manufacturing Resource.

Electric Machine & Fab operates facilities in Williamson, West Virginia, and Sidney, Kentucky, allowing engineering and analysis projects to draw from a broad range of industrial manufacturing capabilities.

Williamson provides extensive industrial machining, electric motor repair, electromechanical repair, and equipment repair capabilities.

Sidney expands EMF's capacity with heavy fabrication, welding, machining, mining equipment rebuilding, heavy equipment repair, and large-format CNC plate processing.

That means our engineering team isn't developing solutions for some theoretical manufacturing operation.

The people who may ultimately build the solution are part of the same company.

Serving Industrial Customers Regionally and Nationwide

EMF serves industrial customers throughout West Virginia, Kentucky, Virginia, Ohio, Tennessee, Pennsylvania, and the greater Appalachian region.

Our engineering and reverse engineering capabilities also support projects nationwide.

Components, drawings, measurements, and technical information can be evaluated for projects originating throughout the United States, while manufactured replacement components can be shipped to customers wherever they're needed.

When Nobody Makes the Part Anymore, Talk to EMF.

Don't let an obsolete component make the decision to retire an otherwise productive piece of equipment.

If you have a worn part, broken component, old machine, incomplete drawing, discontinued OEM component, or industrial problem that doesn't have an obvious off-the-shelf solution, bring it to Electric Machine & Fab.

Bring Us the Problem

Have the original component? Bring it.

Have drawings? Send them.

Have specifications, measurements, photos, or equipment information? Send those too.

And if all you have is a worn-out part and a machine that needs to run, start there.

With engineering, reverse engineering, machining, fabrication, welding, and equipment rebuilding capabilities under one company, EMF can help turn the problem into a practical manufacturing solution.
