The rise of power skiving to a preeminent cylindrical gear cutting process has been one of the gear industry’s most compelling success stories in recent decades. What began many years ago as a promising, but specialized, cutting process alternative for cylindrical gears with challenging interference contours is now exceeding performance and application expectations across the board.
Gear cutting has witnessed remarkable advancements over the years, with modern technologies transforming traditional methods into streamlined, highly efficient processes. NIDEC’s tools and methodologies increase productivity and quality in manufacturing. This article delves into the technological innovations, market relevance, and advantages of their gear-cutting solutions.
Power skiving has evolved from a complex and difficult-to-control cutting method into a viable alternative to traditional shaping or broaching. Liebherr-Verzahntechnik GmbH’s Skiving3 technology package combines machines, tools, and processes to make gear skiving more efficient and flexible. This advancement enables manufacturers to machine a broad range of workpieces, from small to large batch sizes, making it suitable for both series production and contract gear manufacturing.
This report uses an application case to demonstrate the optimization potential of gear skiving in the production of internal splines on a universal machining center. The process established in the example is then analyzed using the software tool OpenSkiving developed by the wbk Institute of Production Science of the Karlsruhe Institute of Technology (KIT) and the results are discussed. Finally, the most important findings are summarized.
The EMAG VSC 400 PS offers the integration of power skiving and turning technologies in one machine, a solution that significantly increases both the flexibility and efficiency of production. By using up to four gear skiving tools and six turning tools, you can produce even complex gears in a single clamping operation, which increases productivity enormously.
The 10th WZL Gear Conference - USA is being hosted by Gleason Corporation in Rochester NY and will provide the opportunity for North American companies to connect with WZL and learn about current research activities. For more than 50 years the annual WZL Gear Conference in Aachen, Germany, has been fostering technical collaboration and communication among the members of the WZL Gear Research Circle. The two-day conference is devoted exclusively to the presentation of the latest research in gear design, manufacturing and testing.
Sandvik has signed an agreement to acquire esco GmbH engineering solutions consulting, a German-based supplier of software for power skiving, an important technology within gear machining. Esco’s software solutions supports design, production and quality inspection in the main area of gear manufacturing. The company will be reported in Sandvik Coromant, a division within Sandvik Manufacturing and Machining Solutions.
Are you looking for a solution to ensure quality and increase productivity in gear manufacturing? There is a clear trend towards saving resources and sustainable manufacturing. Here Liebherr highlights their gear technology, gear-cutting tools, measuring technology, and automation systems.
Power skiving has been turned into a highly efficient process for the production of internal and external gear teeth by the VSC 400 PS machine. The VSC 400 PS can accommodate up to four different power skiving tools on two spindles, plus up to six turning tools.
When developing the AF160, maximum versatility was the key goal of the Engineering Department of the Swiss family enterprise Affolter Group, a world technology leader in high-precision gear hobbing solutions. Vincent Affolter, Managing Director of the Affolter Group, explains: “The AF160 is designed for high precision manufacturers that need flexibility and efficiency. With its eight axes, sophisticated automation solutions, and an innovative quick-change system, the machine provides exactly that.”
Gear hobbing and power skiving processes can be used on the Gleason 100PS, including additional processes like brushing and/or turning operations. Due to the unique flexibility of the 100PS, all gears of a typical e-bike transmission can be produced on a single machine.
Capital Tool Industries (CTI), a leading gear-cutting tool manufacturer in India is pleased to announce the acquisition of long-established gear tool manufacturer Mico Tools (Mishalle NV) in Belgium. The acquisition extends the CTI footprint in Europe and expands its Gear Cutting Tools product line, especially the Power Skiving Cutters.
With expert presentations, live demonstrations and the latest digitalization solutions, the 2023 Liebherr Skiving Day is once again the focal point when it comes to all things gear skiving.
Manufacturers must produce lighter and more compact EV transmissions from tough materials such as low-alloy steels—and those that rely on traditional manufacturing processes risk falling behind. Mats Wennmo, Global Automotive Transmission Manager at the metal cutting specialist Sandvik Coromant, explains why gear skiving is crucial for competitive manufacturing.
Integrated manufacturing solutions for machining processes from the blank to the finished workpiece are the focus of the DVS TECHNOLOGY GROUP's trade fair appearance at the world's leading trade fair for metalworking IMTS 2022 in Chicago.
The ANCA Integrated Manufacturing System (AIMS) optimizes cutting tool production through streamlined manufacturing, automation, and connectivity. With ANCA and AIMS, customers can achieve continuous, unattended production that dramatically reduces non-productive machine time, with smart automation that connects sequential tool production processes and offers connectivity across the whole factory.
The research presented in this paper extends the work done on CAD-based simulation approaches with an investigation of the surface topography of gears produced through gear skiving and the investigation of the cutting tool characteristics on the geometry of the produced gear. The study is complemented with the investigation of the cutting forces required in the machining process.
Sandvik Coromant has appointed two new members to its management group. Michael Eneberg began his new role as vice president and head of global sales on May 1, 2022, while Nicolas Dellachiesa will join as head of merger and acquisitions (M&A) in June. Reporting to Sandvik Coromant President, Helen Blomqvist, both Eneberg and Dellachiesa will play vital roles in driving the company’s global growth forward.
With its brand-new 300GMS nano Gear Metrology System, Gleason presents a world- first at Control Show 2022, May 03-06, Stuttgart, Germany. The capability of measuring gears at sub-micron level, executing advanced waviness analysis and evaluating gear noise using the most advanced analytical tools, make the 300GMS nano ideally suited to support automotive e-drive production with minimum noise requirements.
The company esco, a technology partner for process digitization in the gear and cutting tool industry, is adding a technology module to its software for the Power Skiving process chain.
