The scroll-free turning of rotor shaft sheet metal housings has a number of advantages over the traditional turning process. For one, scroll-free turning provides significantly higher feed rates per revolution, leading to a reduction in overall cycle time. Machine time is also reduced by using the entire cutting edge of the tool – providing the additional benefit of improving tool life. This technology has also proven to achieve significantly better surface qualities.
The VL 1 TWIN has set the new standard for the high-output, simultaneous machining of workpieces with a maximum dimaeter of 75 mm (3 in). This turning center has two main spindles in one machining area that are able to simultaneously machine two identical workpieces – resulting in substantially increased output quantities, and lower unit costs.
High-strength materials, complex geometries, large unit volumes—the production of turbocharger shafts is one of the most challenging tasks in automotive manufacturing. With its new turn-key production system, EMAG has developed a holistic and complete solution. How exactly does it work?
The production of turbocharger components is one of the most challenging tasks in automotive engineering and EMAG has created a complete line solution that delivers both speed and precision.
Large components and complex geometries—in heavy machining, this combination is far from being rare and always synonymous with a high expenditure of time and rising costs. The reason is that the various machining processes from turning to gear cutting are frequently performed in different machines that are not entirely interlinked with one another.
With its vertical turning/milling center VMC 450-5 MT, EMAG Leipzig breaks the vicious circle in an impressive manner: All turning, milling, drilling and gear cutting processes take place in a single machining area. To achieve this, the machine is equipped with five axes. This results in shorter throughput times and a minimal tooling effort—with increasing component quality and diversity.
How can commonly mass-produced transmission components, such as planetary gears be produced even more efficiently? The EMAG Group provides a customized answer to this question with the development of the twin-spindle pick-up turning center, VL 1 TWIN. It machines two identical components simultaneously in the same machining area. This technology opens up a wide range of possibilities: When two machines are combined in a line, the planetary gear can be machined from two sides—and all that is completed with shorter cycle times. What exactly does the line solution for planetary gears look like?
The transformation in the automotive industry is coming fast, and those affected should prepare now— this was the primary message at the 2019 EMAG Technology Forum. The event provided a lot of food for thought for attendees. Which key messages stood out?
The EMAG Technology Forum will take place in Salach on May 15 and 16, 2019
EMAG employs more than 3,000 people worldwide. In addition to the modern production facilities in Jintan and Zerbst, the heart of our company resides at our German technology sites.
In a traditional automatic transmission, a torque converter is installed between the engine and transmission. This core component contains an impeller, turbine wheel and a guide wheel. Driven by the engine, the impeller blade catch oil in the housing which creates a flow that will delayed drive the turbine wheel. This principle ensures a smooth startup and separates the drive train from the engine’s vibrations (referred to as engine irregularities).
