In heavy industry, gears rarely fail in the dramatic way people imagine. More often, there is no broken tooth, no immediate seizure, and no single event that clearly marks the beginning of the problem. What appears to be a healthy gear may already be operating with edge loading, unstable lubrication film, progressive surface fatigue, or overload at the tooth root. By the time visible damage becomes obvious, the failure mechanism has usually been active for some time.


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.

From its origins as a small machine shop to becoming a global leader in precision engineering, Gleason Corporation has continuously redefined the industry. This journey, marked by pioneering inventions and strategic expansions, has left an indelible mark on sectors ranging from automotive and aerospace to robotics and renewable energy.

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.

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.
Discover how next-generation bevel gear metrology combines flank form, waviness, surface quality, and root geometry analysis in a single automated inspection cycle. Advanced software and standard probes deliver faster measurements, deeper diagnostics, improved process control, and enhanced gear performance.
Deburring gears is dusty, repetitive, and hard to staff. The OB7 cobot from Productive Robotics automates it with quick setup and no programming required. Consistent finish on every part, built in the USA. See the full cobot deburring package and request a quote.
Gleason’s new line of high-performance QFS Quick-Flex Segmented Collets are designed for seamless integration with all major workholding systems. Manufactured to the highest standards, they provide exceptional concentricity, durability and clamping force. With their blue vulcanised clamping elements, QFS are a commitment to quality, offering run-out accuracy of ≤5 µm. Put them to the test.
TfG’s RGC 350 Radial Chamfering Machine from Machine Tool Builders produces defined, reproducible chamfers and ‘perfect’ teeth every time. The continuous, high-speed cutting process works wonders even on workpieces with interfering contours. What used to be slow, painful and expensive is now fast, painless, and perfect.
Gleason's Closed Loop System with robot or cobot loading now fully automates the measurement and correction process in gear production. Automatically prompting corrections on connected production machines, the GMSP series not only reduces human error in repetitive tasks, it also increases utilization of inspection equipment up to 90%.
Gear Profile Grinding Machine ZP 10 with automatic tool changer from Kapp Niles. The machine concept stands for maximum workpiece quality, flexibility and a long service life. The basic machines are equipped with a dresser, integrated measuring device, balancing unit and comprehensive software. The machines feature generously dimensioned rotary tables with electrical direct drive and large rotary table bores.


Acute labor shortages, rising costs and global competition continue to push manufacturers to find ways to increase production and improve quality. Productive Robotics will exhibit and demonstrate end-to-end robotic automation in two booths at IMTS 2026. Booth #339186 in the south building will feature ways to automate metal removal processes. Booth #237138 in the north building will focus on abrasive machining, sawing and finishing with a special emphasis on gear production. Unlike conventional cobots, Productive Robotics’ 7-axis OB7 collaborative robots feature zero programming in a plug-and-play configuration.
