The Fundamentals of a Piezo Flexure Linear Slide

There are different ways in which a linear slide can be driven. For instance, it can be driven by a piezo linear motor, a voice coil linear motor, or balls crew or lead screw. These components also find wide-ranging applications in nanopositioning and micropositioning systems. A piezoelectric flexure-guided positioner is one of the most common motion control methods in high precision applications.

A Piezo flexure linear slide can be effectively used in applications such as nanopositioning, biotechnology, quality assurance of medical and electronic equipment, semiconductor technology, microscopy, and dynamic interferometry. Here are some desirable attributes demonstrated by such piezo flexure stages:

They offer virtually frictionless motion, a high bandwidth, and very fast response making the most complex applications possible.

These are available in single as well as multi-axis motion versions. The different combinations include X, XY, Z and XYZ.

With the increasing requirement for vacuum compatible manufacturing, testing, and assembly compatibility, leading manufacturers now offer vacuum compatible versions. These are especially useful in the semi-conductor and biotechnology industry.

There are certain piezo flexure linear slides that offer a record travel range of up to 1800 micrometers. Their resolution can be designed to be less than 1 nanometer. The best part is that they can enable nanometer precision in a matter of milliseconds.

In some cases, the increase in travel range often means a compromise on the space-saving quotient of the piezo-nanopositioning stages. Hence, it is imperative to partner with a manufacturer that can offer increased travel ranges without compromising the compact qualities of the nanopositioning stage.

In a piezo flexure linear slide, the quality of piezo ceramics being used plays a vital role. There are certain motion control equipment manufacturers that also manufacture their own piezo ceramic materials. They employ their own proprietary processes for manufacturing piezo ceramic materials. This ensures that the ceramic encapsulated piezo drives offer a long service life.

Another important attribute that would need to be considered is rapid response and excellent guiding accuracy. This can be achieved with the use of a friction-free and exceedingly stiff flexure system.

These stages are increasingly used in the electronics and medical equipment manufacturing industry. Apart from the actual manufacturing process, a linear slide could also be used for aligning and testing various components. Since these slides do not exhibit any periodic errors, they are highly suitable for quality assurance and testing applications.

A number of nanopositioning and micropositioning applications stand to benefit from the use of a high precision linear actuator. A piezo linear actuator is designed to function in the harshest environments while maintaining its accuracy and reliability. Thus, these linear actuators can be effectively employed in static as well as dynamic operations.
