Durable and Reliable Under All Conditions: What Makes Piezo Actuators Suitable for Industrial and Space Applications?

2014-10-23

Piezo actuators convert electrical energy directly into mechanical energy and allow for motions with a resolution in the sub-nanometer range. They achieve travel up to approximately one millimeter and high dynamics with frequencies up to several thousand Hertz. There are no frictional parts to limit resolution, also no mechanical wear, as motion is based on crystalline solid state effects. Therefore, piezo actuators are the ideal drive solution for many precision applications in industry, life sciences, microscopy, medical engineering and research, and have meanwhile even proven themselves in space.

Piezo Actuators Accelerate Micro Structuring: Good Vibrations for Die-Sinking EDM

2014-10-08

An article recently published in CMM International on how piezo actuators help to drastically shorten production times.

Synopsis: Actuators based on the piezo effect move heavy loads with resolution in the sub-nanometer range and response times below one millisecond, enabling dynamic operation at high scanning frequencies.  Moreover, since they have no moving parts in the conventional sense, piezo actuators are not only very reliable, but are also maintenance free. Diverse applications, ranging from medical and metering technology, to photonics, semiconductor technology, automation and production technology benefit from these characteristics.  In all the applications, piezoceramic actuators contribute to advances in technology.  For example, when die-sinking EDM is used to produce precision components, piexo actuators help to drastically shorten the production times.

Piezo Linear Drives for Laser Technology: Automatic Mirror Positioning in Vacuum and in Inaccessible Places

2014-09-08

Lasers are versatile tools with a wide range of applications. For example, in material processing they are nowadays as indispensable as they are in medical technology or in material and environmental research. Everywhere the principle is the same: Tip/tilt mirrors ensure correct guidance of the laser beam. This makes them important components, which, however, have to be positioned accurately, in order to achieve the desired result. Here manual setting is mostly still the state of the art. But manual adjustment is not always possible, for example, when tilt/tip mirrors are used in a vacuum or are mounted in inaccessible places where they have to be preset before start-up or readjusted. This is where piezo-based linear drives can provide a solution: These space-saving and low-cost microdrives work with a positioning accuracy down to the nanometer range and – when installed in a mirror mount – replace the manually actuated micrometer screws.

PIMag™ 6D

Actively Guided Magnetic Positioning System with Travel Accuracy in the Nanometer Range. Achieving high positioning accuracy is not only possible with piezo actuators. Besides common motor-spindle drives, PI is increasingly using piezomotors for precision motion across longer travel ranges. With the PIMag™ 6D development study, however, PI adopts completely new approaches.

Hexapods Conquer Automation Technology

Standardized Fieldbus Interfaces Guarantee Easy Integration. In many areas of automation technology, precision requirements are becoming more and more demanding. Whenever multiaxis positioning systems are needed, the popularity of parallel-kinematic systems is growing. One example for this is a so-called Hexapod. Standardized fieldbus interfaces guarantee an easy connection to parent PLC or CNC controls so that Hexapods can work synchronously with other components in one automation line.
