There’s a growing list of challenges facing manufacturers today that goes beyond supply chain, energy and workforce obstacles. Many machinists and engineers cite customer requests for shorter lead times, tighter tolerances and improved part quality as imperative to future success. Unfortunately, many standard machine tools lack the necessary functions and capabilities to overcome uneven tool paths, complex surface geometries and long machining times.




An excerpt from Gear Technology Solutions by Dr. Hermann J. Stadtfeld covering when and how individual bevel gear members can be replaced during gearbox service without changing the mating gear.
.
This article demonstrates why bevel gears are designed with a zero sum of profile shifts—showing that independent shifts merely replicate what a modified pressure angle already achieves—and explains the practical benefits of using conical generating gears for tooth profile crowning.
.
This excerpt from Gear Technology Solutions explains how oversized cutter blade edge radii cause root interference in bevel gears, and how to select correct radii to avoid noise, flank damage, and tooth fracture.
.
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.

Cylindrical grinding is an essential machining process in precision manufacturing, ensuring that components meet stringent tolerances with superior surface finishes. Optimizing this process involves a strategic approach to wheel selection, process automation, in-process measurement and machine maintenance. This article explores key technical factors that influence the efficiency and accuracy of cylindrical grinding operations.

When electric drives are used in vehicles, the masking effect of an internal combustion engine disappears, allowing the noise behavior of the transmission to take center stage. At the same time, peak power and torque increase, engine speeds increase, and power must be transferred optimally in both directions due to the regenerative braking system. Conventional design parameters remain important, however: The build space is limited, durability must not be compromised, and the product must still be cost-efficient. Optical metrology as part of a hybrid measurement concept helps to overcome all these challenges.

Gas carburizing has been around for a long time. One could argue that gas carburizing is the most common heat treating process. Heat treaters performing gas carburizing are often characterized by a dirty environment, hazy surroundings, and that “smell.” While the product quality may be acceptable, gas carburized parts do come with some challenges, like excessive intergranular oxidation (IGO) or intergranular attack (IGA), which is often ground off. Low-pressure carburizing (LPC) has proven to be a much cleaner and very capable alternative process. Most furnace companies have combined LPC with high pressure gas quenching, which moved carburizing from the dark back room to a relatively “clean room” environment. However, there is still a strong need for oil quenching, which is the common feature of the long used standard integral-quench (IQ) furnace.
The 80PS Power Skiving and Hobbing Machine is specifically engineered for power skiving, hobbing, and profile milling of small internal and external gears. Configured specifically for the demands of humanoid robotic gear production, it delivers outstanding performance and process stability for gears used in strain wave, planetary, and cycloidal gearboxes, as well as other high-precision applications of comparable size — even when machining fine-pitch gears and thin-walled components.
Profile modifications on gears often mean additional dressing tools, extra costs, and longer lead times. With DIP (dresser-independent profile modifications), Liebherr has developed a generating grinding method that, for the first time, allows for profile modification during dressing using a profile dressing roll, thereby combining flexibility with short dressing times.
