Physik Instrumente has launched a new line of linear nanopositioning systems for a broad range of applications. With large clear aperture, high control dynamics, fast settling times and compact dimensions, the P-630 stages are perfectly suited for use in sensor heads or precision motion of objects in optical and tactile metrology as well as for microstructuring.
With travel ranges up to 80 μm and a direct piezo actuator drive, the compact positioning stages reach high scanning frequencies and settling times of only a few milliseconds. At a width of only 50 mm, their clear aperture is relatively large with a diameter of 30 mm.
The drive technology of the highly dynamic piezo nanopositioning systems is based on all-ceramic insulated PICMA piezo actuators. They have a proven longer lifetime and higher reliability than conventional polymer-insulated actuators. The P-630 stages achieve nanometer-precise positioning accuracy and stability using an integrated capacitive position sensor. Optimum control properties are ensured via the high performance single-channel E-709 CHG motion controller. The digital technology allows for refined linearisation algorithms to improve accuracy while the operating parameters can easily be optimised via software.

Other technologies
The constant need for relubrication of metallic bearing points on rod ends in industrial applications is a time-consuming and expensive exercise and poses a real contamination risk. As a result, igus has developed maintenance-free polymer-hybrid spherical bearings which are a safer and more cost-effective alternative.

It goes without saying that success in Formula 1 requires a top driver. However, their chance of achieving a place on the podium depends on the car, which in turn depends on three essential factors: engine, tyres and aerodynamics. To find the optimum balance, the racing teams test models of their bolides in the wind tunnel. At Sauber, the adjustable components are moved on the model and in the test chamber using FAULHABER motors.
