Festo has launched its latest era of Cartesian-handling-system mechanical axes. The ELGD-TB, tooth belt actuators, and ELGD-BS, ball screw actuators, are based mostly on a brand new Festo design.
Festo famous that its start-to-finish administration of each facet of the ELGD sequence design, testing, and manufacture ensures world-class high quality, a sturdy and dependable provide chain for assured availability, and trade main worth/efficiency. ELGD axes ship distinctive load bearing capability and torsional rigidity, lengthy service life, and elevated reliability in a number of industrial dealing with conditions, from soiled to cleanroom environments.
Suited to most electromechanical dealing with duties, the ELGD sequence brings particular advantages to purposes, equivalent to:
-
Cantilever methods and pick-and-place options for small elements dealing with, the place quick cycle occasions, excessive precision, and repeatability are key
-
Dealing with methods for prime loaders, which profit from the ELGD’s enticing worth/efficiency ratio, excessive journey pace, and lengthy stroke lengths
-
Automation of 3D printing, additive manufacturing, dosing, gluing, and selecting and inserting are enhanced with the ELGD’s dynamic, just about vibration-free motion.

Smaller, Extra Highly effective Axis
Festo inlaid the bearings into the aluminum extrusion and prolonged bearings to the complete width of the axis. This design enhancement permits excessive hundreds in a compact footprint. Machine builders can pack much more highly effective tooth belt or ball screw axes in smaller footprint methods to realize wonderful feed forces and acceleration profiles. The built-in bearing design additionally enabled Festo to develop the decrease profile ELGD-WD (broad actuator) for diminished power purposes. This low-profile ELGD is 30% lighter than bigger models whereas its rigidity and information load capability are comparable.
With the Festo Electrical Movement Sizing on-line productiveness instrument, design engineers enter utility parameters and the instrument finds the proper mixture of CMMT multi-protocol servo drive, Festo servo or stepper motor, and equipment for the axis with all parts completely sized and interoperable.
In 2025, the ELGD axis sequence shall be built-in into the Festo Dealing with Information On-line (HGO) instrument for multi-axis dealing with system sizing and choice. HGO permits customers to design an entire cartesian resolution in beneath 20 minutes, together with CAD fashions and documentation. The Dealing with System arrives as a equipment and is quick and straightforward to assemble with Festo mounting brackets. ELGD axes are additionally suitable with third-party motors. Festo gives a variety of mounting {hardware} to make third-party motor mounting a snap.
The ELGD-BS ball screw drive gives configurable stroke lengths as much as 8.2 ft. The ELGD-TB toothed belt drive gives stroke lengths of as much as 27.9 ft. The ELGD sequence offers a selection of carriage choices, together with an extended carriage and extra passive carriage. The lengthy carriage integrates a second pair of break up ball bearing cartridges, which gives even higher permissible torques to the carriage for probably the most dynamic purposes. The passive second carriage permits the hundreds on the steering to be distributed even additional, basically doubling the utmost permissible torques, load capability, and repair life for the mechanics within the utility.
The ELGD encompasses a stainless-steel cowl strip, which minimizes particle emissions in cleanroom purposes and reduces ingress of particles in soiled environments. Festo enhanced particle emissions functionality by together with a pneumatic connection to supply sealing air (0.1 – 0.2 Bar) or a vacuum to the inner construction of the mechanics. One other innovation is the magnetic deflection of the quilt strip, which eliminates mechanical put on and additional reduces the chance of particle emissions.
