1900 The Future

The company was founded by Robert J. Smith Sr. and Henry P. Smith, shortly after the sinking of the Kings Mine, located just across Highway 41 and a quarter of a mile straight west of HMC. Kings mine, sunk in 1919 became one of the largest Underground Mines in Indiana for over 50 years.

1921

In 1942, after the death of Robert J. Smith Sr., Henry P. Smith took over HMC, directed and grew the company for the next 50 years.

1940’s

The opportunity from the embargo

begin updating our company with advanced technology and resources.

We were able to bring engineers and other technical associates on board and we began acquiring more equipment. By 1980 we were manufacturing quality gearing up to 10 feet in diameter.

1980

By the year 2000, HMC’s Large Gears are furnishing or transmitting power for companies throughout the United States, Canada, Mexico, and Latin America for Bridges, Mining Machines, Steel and Aluminum Equipment, Sugar Mills, Cement and other Aggregate Mills, and for the Military.

2000

Largest CNC Gear Grinder in the World.This gave HMC a "Quantum Leap" in e�ciency with gears Internal/External of up to 240" Diameter and to Tolerances of AGMA 15.

The Rapid 6000 o�ers HMC Unique Inspection Capabilities. HMC has the unparalleled capability to chart

Runout, on Gears of 240" Diameter.

2008

Princeton Farms was founded by Robert J. Smith Sr. and Henry P. Smith in the early 30’s. A major part of its business was raising and packaging Popcorn. Part of our heritage included Orville Redenbacher. His start in the Popcorn industry began at the Princeton Farms.

1930’s

The 1973 Oil Embargo had begun. Crude oil went from $3.00 to $50.00 a barrel thus causing gasoline prices to increase as much as 300% overnight. Contract Coal went from $3.00 to 30.00, and spot market coal reached $60.00 a Ton.

The OEM’s of Mining Machinery at this point became inundated with new machine orders and their lead times for delivery of replacement parts went out to as long as several years. Overnight many surface mines discovered that the replacement parts and service they required for their machines was nonexistent. This chain of events presented HMC with the opportunity it needed.

1973

In the early 1990’s we developed a Marketing Campaign that would expose us to industries nationwide. Within a short period of time this venture became promising enough to

forward in 1994 with our Year 2000 Expansion and Updating Plan.

This planning encompassed new buildings, machine tools, inspection equipment, more welding technology,

departments with additional technical resources, all of which required spending millions of dollars.

1990’s

In 2007, HMC completed building a new Super Heavy Welding and Fabrication Facility. This new facility allowed us to move our welding from our 18,000 sq. foot High Bay Buildings and double our welding capabilities in this Brand New Building. It is supported by 2 - 50 Ton Cranes. We also added a huge new Stress Relieving Oven, Manipulators, Turning Rolls, Lay-out Tables, and much more.

2007

New 8-meter manufacturing and inspecting capability. HMC now has the ability to specify, design, manufacture and verify gearing up to 315” in diameter. We are one of very few companies in the world possessing this capability.

Our Modern Vertical and Horizontal CNC Custom Machining Centers and Horizontal Lathes enable us to turn, contour, face, spot face, mill, drill, or produce close

We are able to maintain the tightest tolerances on parts even when they exceed 20' in Diameter.

And if your problem involves Large Shafting or other components requiring Turning in the Horizontal Plane, (No Problem), our Lathes will facilitate Diameters of up to 82” that are 396” long.

Large Component Machining is one of our key strengths.

welding and fabrication

The di�erence begins with HMC selecting the best materials for your Weldment Designs. Our Weldments are made of Materials with Special Alloys such as Nickel, Vanadium, Molybdenum, and Chrome. These Alloys make the di�erence in a material's ability to Deform and Absorb Stress without Cracking or Breaking; (Impact Values).

HMC's long-time success with the manufacturing and proper heat treating of Heavy Weldments has established our reputation as one of few World-Class suppliers of Forged Fabricated Gears and other Large Mechanical Components.

"We will compare our World Class Welding sta� and their

any in the world."
