The notion that any type of linear actuator can be chosen for any axis in an X-Y-Z system will be challenged by HepcoMotion at the 2010 Machine Building Show (Birmingham NEC, 27/28 April 2010, stand 1630). The demands on each of the axes vary considerably so a one-type-fits-all approach will ultimately compromise performance, reliability and the service life of the overall system.

On a specially developed demonstration unit HepcoMotion will show that, with the correct choice of linear actuator, each axis will operate optimally. The company has developed a family of actuators to address the different characteristics in each axis. If required, these can be incorporated into a chassis made from the MCS machine construction system and given intelligent control through HepcoMotion's partnership with Smart Drive.

The demonstrator will show the HepcoMotion PDU2 linear actuator operating as the X-axis foundation of the system. This hugely popular product features the ultra-high-performance Herculane wheel technology in a compact and cost-effective belt-driven unit.

As a Y-axis typically requires high load capacity and stiffness against twisting loads, the PDU2M is used due to its high moment load capacity. And the needs of the Z-axis are different again, with enhanced linear force and higher gearing being a common requirement. The new PSD80 is therefore suitable for this task, with drive from a super-smooth stainless steel lead screw operating with a bearing polymer nut. It, too, uses Herculane wheel technology in a unit that is matched to the other axes in terms of performance, size and cost.

HepcoMotion supplies it X-Y-Z systems as individual parts, in kit form or as fully assembled units.
