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.
With global wind turbine demand set to quadruple by the end of the decade, manufacturers are seeking new technologies to ramp up production of gears that can operate in any environment, around the clock, for years to come.
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.
TCI Precision Metals has announced the expansion of its grinding services to meet the needs of customers wanting more value-added materials processing. Customers who have traditionally sourced materials and shipped them to and from TCI Precision Metals for specific grinding requirements can now eliminate additional in-house processing, shorten materials lead times, and increase production efficiency. TCI can source materials mill-direct, precision cut oversize, then grind or mill two or six sides to close tolerance customer specifications.
For the transmissions of electric vehicles to develop the desired high torque under all driving conditions, a very large gear ratio is needed, which requires high speeds. And to ensure sufficient momentum at all speeds and enable the driver to accelerate without shifting gears, the electric drive must achieve up to 15,000 rpm, which is about three times that of a typical combustion engine. This puts a lot of strain on the rotor shaft. The manufacturers of rotor shafts are thus facing new challenges, such as the significantly lower shape and position tolerances and the need for greater machining precision.
C&B Machinery (C&B) announced the completion of their newly redesigned Clamp Bore Face Grinding Machines. After months of planning, redesigning, and building the machines, C&B is excited to announce the latest CBVR-2F-2S model Clamp Bore Grinders.
Bourn & Koch, Inc. of Rockford, IL, is pleased to report that Ross Wegryn-Jones has recently joined the company as our National Sales Manager. Ross will be responsible for the sales of gear manufacturing machines, precision grinding machines, and specialty machine tools for unique manufacturing applications. This includes Bourn & Koch horizontal gear hobbers; Fellows gear shapers; Blanchard rotary surface grinders, and Bourn & Koch’s new MT3 vertical grinding machine.
Manufacturing high-accuracy worm gears and screws alongside precision spur and helical gears has traditionally required the use of two quite different CNC grinding machines. Thanks to PTG Holroyd’s newly launched HG350-WG worm and gear grinding center, however, just one machine can now complete both tasks.
