This pay-off calculation offers only a rough guide value. It is based on a RoboTrex 52 automation system with four fully equipped trolleys or a RoboTrex 96 automation system with two fully equipped trolleys. Country-specific and currency-related deviations are not taken into account. It is to be assumed that during these additional machining hours other value-adding tasks take place or that the automated machine tool operates unmanned (e.g. at night).

RoboTrex at a glance

Efficient in every way

Off-line loading of trolleys

Trolleys are prepared off-line without interrupting the machining cycle. Vises don't even have to be removed from the trolley to be equipped with workpieces.

Quick loading of automation system

Trolleys are exchanged within just a few seconds.

Easiest operation

Training is kept to a minimum thanks to a pre-adjusted and pre-programmed robot with a simple, user friendly control.

Flexible and movable storage

Trolleys are not bound to a specific Robo Trex, but usable throughout the entire production area. For quality control or other tasks, trolleys can be removed even during operation. An easy and unrestriced access to all vises is guaranteed.

Ideal storage capacity / required space ratio

Patented, angled mounting of vises ensures maximum utilization of space and best accessibility when exchanging workpieces.

No additional utilities necessary

Actuation of the zero-point system can be done either mechanically (RoboTrex 52) or pneumatically (RoboTrex 52 and 96). Various gripper options ensure utmost flexibility.

Start and stop mark
Auswahl von Start- und Endpunkt
The first and last vice position can be selected manually, thus limiting the are of the vices to be picked up. Once the stop mark has been reached, the operator can decide whether the automatic sequence should be continued after this position or whether it should be finally aborted. This state can be used e.g. to carry out service tasks on the machine or quality controls on the manufactured parts when the machine tool is empty and the robot is in sleep mode.
Deselection of vice positions
Ausblenden einzelner Positionen und Reihen
A new function makes it possible to define individual trolley equipping patterns and allows a deselection of certain vice positions or even entire rows This means that taller or wider workpieces can be automated with RoboTrex without having to use a custommade trolley. The function also includes the option of assigning the selected assembly pattern to one or more trolley spots.
Individual program assignment
Individuelle Programmzuweisung
A new interface enables an automated single-part production with RoboTrex. An indiviual NC program can be assigned to each vice position on the trolley. This requires a corresponding automation interface on the part of the machine tool. The processing of the parts on the trolley can, if necessary, take place depending on their priority, which means that a desired sequence is possible. If parts have the same priority, processing is done according to the position number on the automation trolley.

  • Workholding and Automation - all from one source
What favors the RoboTrex Automation over other palletizing and part handling systems?

Benefits of RoboTrex

over other palletizing systems

With the LANG system, vise and pallet build a compact unit. This results in high space savings in the machine, as well as a high storage capacity of the entire automation system on a small footprint

Compact vise (without additional pallet) grips workpieces which can substantially exceed the vise’s volume, whereas competing systems usually use big pallets (e.g. 400 x 400 mm) to clamp relatively small workpieces

There is no additional vise-pallet interface, which has a positive effect on stability and manufacturing accuracy

Thanks to simple communication between automation and machine tool, the installation of the RoboTrex system, which is delivered in a ready-to-operate state, is very simple and hardly time-consuming. As a result, downtimes of the machine tool can be avoided almost completely

Automation trolleys are equipped with vises off-line and location-independently. Within just a few seconds the automation system is fed with fresh trolleys and ready to machine a new batch

One-touch operation gives the operator access to the entire storage. The accessibility to each vise point is guaranteed. This allows immediate (quality) control of the finished parts even during operation

over part handling systems

RoboTrex comes with a single gripper, no matter which workpiece size or shape, no adaptation of the gripper is required for different workpieces

Thanks to the Makro•Grip® stamping technology, many compact vises can be stored on the smallest possible footprint. At the same time, the stamping technology guarantees maximum process reliability in milling

RoboTrex uses the same storage medium for all workpieces, which makes the system universally applicable even with high vertical integration

The automatic (un-)loading is independent of the milled contour, since the Makro•Grip® 5-Axis Vise is the handling interface. No problems with bulky parts

Thanks to the accuracy of the zero-point clamping system and the defined gripping contour of the Makro•Grip®, a quick and easy reproduction of the clamping situation is possible if workpieces have to be re-clamped for any necessary reworking

For manual non-automated manufacturing, the Makro•Grip® 5-Axis Vise can be used at any time in other machines, which maintains flexibility in production at all times
