Water Spray Quenching—A New Intensive Quenching Process for Case Hardening of Gears

Water spray quenching achieves heat transfer coefficients up to 4,000 W/(m²K)—nearly double conventional oil quenching rates—enabling potential material substitution and tailored quench intensity for complex gear components.

Analytical Calculation of the Gear Body Stiffness of Face Gears

This paper presents a new analytical method using plate and disk mechanical models to calculate the gear body stiffness of face gear wheels, showing that stiffness decreases toward the outer radius—a behavior that conventional cylindrical gear approaches fail to capture.

Conjugate Bevel and Hypoid Gears

An excerpt from Gear Technology Solutions by Dr. Hermann J. Stadtfeld exploring the mathematics behind conjugate bevel and hypoid gears—from the fundamental laws of gearing and the conditions for perfect conjugacy to why real-world power transmissions require deliberate crowning rather than theoretically exact conjugate designs.

Smart Alloying Eliminates Manufacturing Steps in Automotive Gears

20NiMo9-7 alloy achieves up to 48 percent higher fatigue strength than conventional carburizing steels in the as-carburized condition, eliminating the need for shot peening and grinding in automotive gear applications.

Design

The objective of this paper is to improve the methodology for determining the tooth flank temperature. Two methods are proposed for assessing scuffing risk when applying AGMA 925 for high-speed gears. Both methods provide similar results.

Grinding

The Swabian transmission and drive solutions manufacturer SPN Schwaben Präzision Fritz Hopf GmbH manufactures gearboxes, gears, and drive systems according to individual customer requirements.

NVH

The arrival of Gleason’s Hard Finishing Cell (HFC) in 2018 represented a paradigm shift in the way automotive transmission gears and gears for e-drives, could be produced in high volumes. Now, for the first time, 100 percent inspection of every gear, and every gear tooth was possible in-process, without impacting the high speeds at which these gears need to be hard finished. Identifying, and correcting for, conditions that create unacceptable noise behavior in these gears, on the fly, was finally a reality too.

Heat Treating

Various in-situ methods can track realtime heat treatment response in bulk materials. This can aid material engineers in designing the most effective heat treatment procedures and processing methods. In-situ  methods such as thermogravimetry (TG), differential thermal analysis (DTA), and dilatometry, offer capabilities to examine heat treatment behavior in real time, giving insight into the thermochemical mechanisms and the thermal behavior of steel.

If This Old Machine Can Be Automated, Yours Can Too

Productive Robotics sets the new standard for simplifying robotic automation. OB7 ensures simplicity in use and versatility, easy automation of existing production and new set-ups, increased output, consistency, and quality. It emphasizes teaching the robot rather than programming. Productive Robotics' OB7 collaborative robots are currently used in many diverse applications due to their simplicity, capability, and affordability.

Industry News

New orders of metalworking machinery, measured by the U.S. Manufacturing Technology Orders Report published by AMT – The Association For Manufacturing Technology, totaled $605.8 million in July 2026. This was an 8.0% decrease from June 2026 and a 55.2% increase over July 2025. This is only the second time since USMTO began collecting data in 1998 that orders have exceeded half a billion dollars for five consecutive months. Through the first seven months of 2026, manufacturing technology orders totaled $4.03 billion, a 37.1% increase over orders placed through July 2025.
