With their VL 5i the machine tool specialists at EMAG have developed a comprehensive solution for small and medium size manufacturing companies. It can be used for small and large batch production, and complete-machines workpieces of up to 250 mm in diameter in a single setup. Flanges, gears, gear shafts and steering pinions can be machined with as much efficiency and to the same quality as brake disks or cams. The machine features a powerful 28 kW workspindle with a top torque of 300 Nm, plus a turret that accommodates turning as well as driven tools and has an impressively short indexing time of 2.2 s. Drilling and milling operations can be incorporated by equipping some or all of the 12 turret stations with driven tools. The outstanding feature in this is the EMAG turret drive that combines high speeds with outstanding performance and a small space requirement. For instance, the diameter of the turret is only 360 mm but accommodates 12 stations and has a maximum torque rating of 45 Nm.
Flexible automation included
Proof of the outstanding quality of the VL 5i is, first of all, its integrated automation system. It uses a recirculating chain conveyor equipped with carrier prisms that deliver the raw-parts directly to a pick-up station for machining. This station is located behind the machining area, so the operator can – at any time – insert new raw-parts at the front of the machine. It is hard to imagine a more flexible and, at the same time, more universal solution for the automation of a machine tool.
Short travel times = short idle times
Another advantage of the VL 5i is its short idle times. Changing workpieces is a very fast process, because the distance between the loading position and the machining position is only 550 mm. The importance the EMAG turning specialists attach to the machine’s efficiency can also be seen in the design of the guideways. They are located outside the machining area, where they are protected against chips and dirt. This reduces the maintenance effort and makes the machine less susceptible to breakdowns. The machine can also be equipped with an optional measuring station, located outside the machining area. Here the component is measured on its way from the tooling zone to the unloading station, while still in its original clamping position. The measuring results are not distorted by the entrance of chips, as the vertical turning operation provides for ideal chip flow conditions.
Energy efficiency is very important
The sustainable use of energy and resources completes the picture of an engineering solution that not only offers a small footprint but also eliminates unnecessary design details which is the reason why the machine builders at EMAG can offer this machine at an advantageous price-performance ratio.
