VL 2 and VL 4 for small and medium-sized workpieces
The VL 2 and VL 4 pick-up turning machines are ideal for workpieces with a diameter up to 100/200 mm. They feature integrated automation and a parts storage area, which enables them to operate completely autonomously, relieving the strain on production personnel. Efficient mass production of varying batch sizes is possible and, thanks to flexible clamping systems, they can also easily machine whole part families.

MODULAR CUSTOMIZED SOLUTIONS
VLC pick-up turning machines – more than just turning
Various manufacturing technologies can be used flexibly on these machines. In addition, they are extremely compact and have powerful drive units in their spindles and axes, which ensure they have plenty of capacity at all times. The great flexibility of the equipment and powerful working spindles are supplemented by the integrated automation solution using pick-up spindles.
The machining area in VLC machines can be configured flexibly. For the turning process, the twelve tool positions in the tool turret can be equipped with conventional and driven tools.

THE EMAG TURRET
The high-speed 12-station disk-type turret features very short swiveling times. Driven tools can be used on all twelve turret stations for drilling or milling operations. The EMAG turret gearbox combines high speeds with high capacity while requiring minimum fl oor space.
+ Very high speed
– Very short swiveling times
– High speeds when using driven tools
+ Very high capacity
– Very small design with high torque
+ Very high precision
– Turret firmly embedded in the machine base = High rigidity
– Very high degree of repeat accuracy when indexing from tool position to tool position
+ Very high availability
– Inured to collisions, owing to the use of torque motors
– No raising of the turret for swiveling. This means that no chips or dirt can get into the turret.
VSC MULTI-SPINDLE MACHINES
VSC DUO – the twin-spindle machine for sequential operations
The VSC DUO principle offers a highly efficient solution for the machining of medium to large numbers of parts on a minimal footprint. The work areas are completely separated. This allows the axes to be programmed independently of each other. This makes it possible to realize sequential operations in one machine.
TECHNICAL DATA
TURRET
Both turrets accommodate not only stationary turning tools but also driven drilling and milling tools. This allows for either identical or different operations to be carried out in the two spindles:
+ After the first set of operations have been carried out on the workpiece, using the first spindle, the back of the component is machined in the second one; or the second spindle could be used to machine the workpiece in the same clamping position.
+ Two workpieces can also be machined with identical operational sequences.
VSC 250 DUO: Separate, extremely sturdy machine bodies made of MINERALIT® polymer concrete; the two overhead slides are independently programmable.
VSC MULTI-SPINDLE MACHINES – TWIN MACHINES
High-speed turning machine for large-scale production
Over the years, EMAG has developed vertical turning machines that load themselves by moving the main spindle and performing various operations in a single clamping operation. In addition, there is a consistently symmetrical slide and machine structure for thermostable production. The VSC 160 TWIN is one of the fastest turning machines on the market for components up to 130 mm in diameter.
SIMULTANEOUS MACHINING
+ A single machining area with two working spindles
+ Simultaneous machining of two workpieces with identical operational sequences
+ Machining operations for workpiece diameter and length can be corrected for each working spindle individually
HIGHLY DYNAMIC, PRECISE AND RELIABLE –THE VSC 160 TWIN
+ The working spindle with hydrostatic bearings in the Z-axis ensures outstanding component quality and a high tool service life for soft and hard machining operations.
+ Closed, thermosymmetrical structure with machine base made of vibrationdamping MINERALIT® polymer concrete.
+ Good chip fl ow thanks to the vertical design » Low-wear guiding elements
+ Cooling system for spindle motor, machine body, spindle, and turret
+ Turret for 2 x 4 tools

TURNING MACHINES SHAFT PARTS FOR
VT MODULAR SOLUTIONS
Fast processes are required for machining large quantities of shafts. Both the machining process and the loading and unloading processes must be completed extremely quickly. The VT 2 and VT 4 machines are guaranteed to achieve the maximum performance you require.
Four axes, short distances, and a powerful main spindle – these are the strengths of the VT Series. The full effect of these can be felt, in particular, when machining large quantities. A key factor is the machining of parts from two sides. This greatly reduces the machining time. Two tool turrets, each with eleven tool positions which can be equipped with turning tools or driven tools, ensure machine fl exibility.

THE BENEFITS
+ The standard machine comes prepared (“tunnel”) for integration with the TrackMotion automation system.
+ Reduced machining times due to four-axis machining
+ Shorter idle times with simultaneous loading and unloading of components
+ Lower investment costs thanks to integrated automation
The gripper in turret 1 takes the workpiece from the raw parts storage area and transports it to the main spindle/tailstock. At the same time, the gripper in turret 2 takes the machined workpiece from the main spindle/tailstock, transports it to the finished parts storage area and deposits it there.

VTC MODULAR CUSTOMIZED SOLUTIONS
VTC machines are available in either a single spindle or DUO version.
With a DUO version, this single machine operates like two four-axis turning machines, and offers a variety of machining technologies in its two stations. These machines are increasingly being converted into multifunctional production centers that include finishing operations such as cutting to length and centering. These operations prepare the parts for additional four-axis turning or more processes downstream. All of this is completed in a fully automated cycle on a single machine.
The spindle motor, main spindle, tool turret and electrical cabinet are all fl uid-cooled. With their great power, high spindle speeds and sturdy turrets, the machines of the VTC Series are highly productive turning centers for shaft machining. In addition to workpiece grippers, every turret can be equipped with stationary turning tools or driven drilling and milling tools. Furthermore, the machining area can be fitted with additional technology modules if required.
