Gear hobbing machine VLC 250 WF – Turning & gear hobbing & deburring

Manufacturing system for gear hobbing of precision gears

The VLC production line is designed for the mass production of wheel-shaped workpieces featuring gearings, and covers the complete machining process for workpieces of up to 200 mm in diameter and gear module 4. The gear hobbing machines of the VLC Series can be equipped to match all required processes, including turning, grinding and gear hobbing.

The VLC 250 WF is designed for the manufacture of wheel-shaped workpieces with a diameter of up to 220 mm and gear module 4 and offers the user greatest possible flexibility, as it can be used as a single-spindle turning machine, a gear hobbing machine or a combination of both. In other words, the user gets two fully fledged machines, which he can use as and when a change in components demands.If an additional operation is called for -- roller burring, for instance -- this can be integrated in a separate machining station. The main application, however, is the precision machining of gear profiles on medium and large batches of components.

VLC 250 WF – Individually configured automation
The gear hobbing machine VLC 250 WF can be automated in various ways, with the equipment configured according to customer requirements and designed to keep travel and idle times at a minimum. The EMAG ILS (InLine System) allows for the machines to be positioned close to each other, forming a straight line. Maintenance and service doors located at the back of the machine were designed so the individual machines can be easily accessed. This arrangement is great for a batch production, e.g. gear hobbing, because it allows “in-line” component flow between two or three machines. The interface points between machines can then be utilized with the insertion of optional component buffers or docking stations. The ILS makes it possible to create the manufacturing system with the smallest footprint.

Advantages

  • The second side of the component can be turned and the gear profile hobbed in a single setup
  • Auxiliary operations, such as deburring of the gears with a turning or a roller deburring tool, are easy to integrate
  • Automation concepts with directed component flow – such as the EMAG InLine System – as well as standard recirculating component conveyors are available
  • Compared to the traditional solution of a combined turning & gear hobbing machine the VLC 250 WF offers a truly remarkable price-performance ratio
