Vertical shaft machining VTC 250 / 250 DUO VTC 315 / 315 DUO VTC 250 L

The VTC series of machines are designed for the vertical machining of shaft-type components. Users of these vertical turning centers prot from minimal throughput times, true process capability and outstanding precision. These machines provide for the completemachining of shafts on a single machine – automation included. Technology modules ensure the VTC machines can be customized to suit individual machining requirements. V V V V 2 T T T T C C C C 2 2 3 3 5 5 1 1 0 0 5 5 D U O D U O

VTC – machining shafts to perfection. The development of the VTC series of The vertical construction guarantees machines followed the same governing unimpeded chip ow, making it hardly principle that led to the success of the ever necessary to remove chips EMAG chuckers. As with all EMAG manually. This is very important in turning and production centers, the soft-machining, because the process cornerstone of the design is the sturdy frequently produces large volumes of MINERALIT® polymer concrete machine chips.

Complete-machining shafts. The VTC is available with a single spindle Advantages of the VTC series: or in its DUO version. The DUO combines the functions of two four-axis turning machines and oers dierent machining technologies on its two stations. These machines are increasingly being converted into multi-functional production centers • Four-axis machining reduces cycle times • Concurrent loading and unloading of the workpieces reduces idle times which minimizes cycle times • The compact design makes for a that include, for instance, endworking small footprint. Lower capital outlay...

• Short set-up and resetting times The cycle time-concurrent loading and • Less capital outlay for sensory unloading is accomplished by the turrets. equipment due to direct driven Example: automation on the VTC 250 DUO machine axes and modern control The gripper in turret 1 collects the technology workpiece from raw-part storage and • A smaller number of set-ups and conveys it into the rst clamping better component quality through position. complete-machining The gripper in turret 2 removes – the machined component from the rst clamping position and conveys it to the second one. The gripper...

VTC production lines. The VTC series of machines is designed When production requirements change, to handle complex manufacturing the machines of the VTC series can processes. Whether the job includes easily be equipped with dierent the high metal removal rates of turning technology modules for the new and milling or a grinding process – workpieces. the machines oer the possibility to integrate most metal cutting processes. This makes them perfect for the formation of complete production lines for soft- and = hard-machining. Applications that include turning, milling, drilling, grinding and...

The following technologies are available: • Soft-turning • Milling (side-and-face cutter) • Drilling • Gear hobbing • Hard-turning • Scroll-free turning • Grinding / simultaneous grinding • Out-of-round turning This guarantees exible use of the machine and provides access to a wide range of applications, as the technologies can also be used in a variety of combinations.

VTC 250 L – Shaft by shaft … The VTC 250 L is a lean-design vertical The vertical design of the machine also shaft machining center. The machine is oers a footprint that is up to 50% less designed to run as a stand alone or as than that of a horizontal turning machine. part of a production line based on the chaku-chaku principle. All VTC machines incorporate integral automation. That means the machine always does what it does best: PRODUCE – regardless of whether its operator is at the machine, taking a break or there is a shift change. V T C 10 2 5 0 L

The advantages of the VTC 250 L: • Can be used as stand alone or part of • The vertical design of the machine a production cell based on the ensures the unimpeded ow of chips chaku-chaku principle and prevents the build-up of chip • Integrated workhandling: The EMAG turret reduces the cost of automation equipment and peripherals • Raw-part and nished component storage areas form an integral part of the machine • Tailstock and steadies are clusters • The compact vertical design makes for a smaller footprint • Great accessibility and operator friendliness ensure short setting and resetting...
