Combined machine tool completes complex machining at one time

Due to the significance of gear production in various fields, the research on gear processing is in the ascendant: research on hobbing tool coating, development of high-speed machine tools and optimization of hobbing process have always occupied a core position. There is only one goal for this kind of research: to reduce the cost of one-piece production and improve the quality of parts processing. Due to the geometric complexity of the gears and tooth engaging elements, the complexity of the machining is conceivable.

According to experts' estimates, about two billion gears are produced every year in the world (most of which are machined by the hobbing process), and the number of gears used in automotive gearboxes is very large. Gear machining is characterized by complex shapes and demanding quality, especially for toothed engagement elements. Faced with this challenge, most users still use the traditional processing method with a long process chain: that is, turning, hobbing and deburring are performed separately on their respective machines, so the whole process of gear processing takes a long time. EMAG gear hobbing experts and designers have another shortcut to provide fast production methods for gear processing. VSC 400 WF (WF is the abbreviation for German hobbing) and the VLC 250 WF vertical machine integrates all the processes of gear machining into one machine, enabling turning, hobbing and deburring in one setup. "Leap" style improved.

Advantages of car rolling

Gears generally require two turning and one hobbing. We can use gear machining as an example to illustrate the advantages of combined machining: although the old process (processed through three different equipment) and the new process (through a set of turning and Compared to the hobbing process, the main machining time (turning and hobbing time) is similar, but the non-machining time of the new process is much lower than the old process. When the new process is used, the production efficiency has been greatly improved due to the saving of the loading and unloading time. In addition, the production system using the EMAG rolling technology can improve the machining accuracy, reduce the scrap rate and reduce the machine footprint.

Turning and hobbing applications

It is suitable for large and medium batch processing of various gear parts, and it is faster and more precise than traditional processing methods. Due to the wide variety of gears, gear shafts, clutch system parts, synchronizing gears and other gear-type parts, and the large output, the roll-rolling combination process is extremely widely used.
