Company Profile: Gear Technology

Long known for quality and precision, this company continues making strides in the commercial aerospace and defense industries, with new markets on the horizon.

When he was a student at Loyola Marymount University, Tom Marino used to watch planes land at the nearby Hughes Aircraft plant in Culver City, California. Little did he know at the time how the activity he observed would eventually figure into his own future.“My father, James John Marino, was a WWII bombadier who ended […]

A New Approach to Shop-Floor Gear Inspection

Marposs has responded to a need for a shop-floor inspection system, allowing for real-time inspection of gears in various stages of production without the need for skilled setup.

Gear production is one of the most difficult tasks to be found in modern manufacturing. Producing complex, non-linear, three-dimensional geometries in hard, strong materials with an extremely high level of precision is a daunting challenge in its own right. Inspecting the results of the various manufacturing operations to assure consistent quality and performance is even […]

Axis of Rotation Metrology for Improved Gearing

Spindle metrology can help you produce better gears, and it is an excellent new tool for diagnosing error sources in the machining process.

In the history of machine tools, spindles have been very good relative to other bearings and structures on the machine. So quality professionals have developed a cache of tools—such as ball bars, grid encoders, and displacement lasers—to help them characterize and understand the geometry of the whole structural loop. This makes sense, as this is […]

New Gains in Grinding Pinions

In building a machine that completely grinds pump pinions in a single clamping Junker presents a unique production technology, and the ability to replace three machines with a single unit.

The demand for lower costs and higher flexibility are shaping modern production more than ever before. Mechanical engineering companies are in turn required to develop ever more advanced, flexible and economical machines. Erwin Junker Machinery—headquartered in Germany, with its U.S. location in Elgin, Illinois—attempts to meet these challenges every day. As an example, since 1985 […]

Gear Hardening Goes Green

As the gear industry reinvents itself, “green manufacturing” gains prominence by factoring all aspects of the process into achieving efficient outcomes.

In his annual message to Congress in December of 1862, President Abraham Lincoln concluded with the words “We can succeed only by concert. It is not ‘can any of us imagine better?’ but ‘can we all do better?’ The dogmas of the quiet past are inadequate to the stormy present. The occasion is piled high […]

Gear Tooth Fillet Profile Optimization

In this article you’ll learn about a fillet profile optimization technique that allows for substantial bending stress reduction, producing a variety of gear performance benefits.

Historically, gear geometry improvement efforts were concentrated on the working involute flanks. They are nominally well described and classified by different standard accuracy grades, depending on gear application and defining their tolerance limits for such parameters as runout, profile, lead, pitch variation, and others. Working involute flanks are also modified to localize a bearing contact […]

Cryogenic Treatment of Gears

Utilized to transform retained austenite and raise the hardness of the as-quenched structure, better dimensional stability is often achieved as a result of cryogenic treatment.

Most companies are looking for a secret that can help them keep a step ahead of the competition… a little edge to run faster, cheaper, and more efficiently than the competitor. That secret is cryogenics. Cryogenic processing—the deep chilling of tool steel so that the molecular structure of the metal is brought to “cryogenic stillness” […]

DEPARTMENTS

Terry McDonald: Site Safety

During tough economic times employees are under more stress than ever before, with personal and work-related pressure increasing daily. Open communication can help.

Stress… is this a serious safety issue? How does stress affect your workplace? Do you bring your stress from home to work with you? What about the economic stress that we are all currently operating under? Does your “boss” stress you out? Are you one of the lucky ones who have survived the layoffs? I […]

While metal casting is a fairly straightforward process on its surface, different methods suit particular applications

Metal casting—pouring molten metal into a mold until it solidifies—is an ancient process. Early civilizations learned that, by using this method, the mold shape would be duplicated. In early times little was known about solving casting problems, but today these factors are closely controlled, with new techniques, processes, and computers providing precise control. Modern-day foundries […]

Chris Chlon: Buy Laws

When approaching buyers, what are the best tactics? What are they looking for in a vendor, and what are they thinking about your presentation? Read on for insights.

On any given day industrial buyers are tasked with project team meetings, negotiations with suppliers, resolving invoicing, and various problems related to their job. They also must meet or speak with current suppliers, bidders on projects, and deal with calls from potential suppliers.In these tough economic times sales representatives responsible for finding business with new […]

Q&A with Gerald Shankel

President & CEO Fabricators and Manufacturers Association, Intl.

Opening kids’ eyes to manufacturing as an exciting career is important. Tell us what the FMA is doing in that area. You’re right, it’s critical that all of us involved in manufacturing make them aware that the image they may have from pictures of the Industrial Revolution in their textbooks no longer holds true, and […]
