This article introduces the process of polish grinding of gears. Improved surface quality increases the overall efficiency of gearboxes, resulting in reduced friction and torque loss, higher power density, and noise-optimized gears (lower NVH); all these factors are highly relevant, especially for electric drives. When Reishauer developed polish grinding in 2012, the process aimed to improve the efficiency of ICE engine transmissions, and the set goals were easy to achieve. Today, in 2023, the situation is dramatically different. While an ICE engine operates at around 3,000 rpm and supplies acoustic masking of the gear noise, EV drivetrains feature up to 20,000 rpm and offer no such masking.

The FX7 Ultra is a refined solution for precision grinding in industries that rely on small tools, including electronics, telecommunications, medical devices, aerospace, automotive, die mold, and general machining. 

Star Cutter Company has acquired Tru Tech CNC grinding systems from Resonetics (Nashua, N.H.), assuming all design and manufacturing of the Tru Tech high precision CNC grinding machines currently performed at the Michigan facilities in Mt. Clemens and Lewiston. Additionally, Star Cutter secures the service, training, and spare parts support for Tru Techs’ vast installation base across North America and Europe.

At EMO 2023 in Hannover, Germany, the United Grinding booth in hall 11, booth E34 will showcase 16 machines, innovative technology, and updates from the Customer Care team. The United Grinding Group, one of the world's leading manufacturers of grinding, eroding, laser and measuring machines, is considered one of the pioneers in the development of innovative technologies in the manufacturing industry. Fittingly, ”Innovate Manufacturing” is the motto of this year’s EMO in Hannover. 

2023 is shaping up to be our planet’s hottest year on record, and the wind energy industry is feeling the heat. The GWEC (Global Wind Energy Council) says that the rate of wind turbine installations will need to quadruple globally by the end of the decade if we’re to achieve the IRENA’s (International Renewable Energy Agency) goal of net zero carbon emissions by 2050—and keep the average annual temperature worldwide from increasing more than the predicted 1.5° C. Fortunately, “net zero” commitments are gathering global momentum. Before year’s end, total global windpower is expected to reach a historic milestone of 1 TW of installed capacity, eliminating 1.2 billion tons of CO2 annually, roughly the equivalent of all the carbon emissions of South America.

This article describes a cloud-based process and machine component monitoring system called ARGUS. The term “swarm” is used for a large population of gear-grinding machines of individual and independent customers connected to the ARGUS system and the ARGUS cloud. These “swarm” machines permanently feed their anonymized process data into a common cloud database. Reishauer uses this database for big data analytics to discover patterns that indicate successful process and machine component behavior patterns worth integrating into the ARGUS algorithms and propagate them across the complete ARGUS customer base.
