Kreuzrollenführung
With crossed roller guides, the point contact of the balls in ball guides is replaced by line contact of the hardened rollers. Consequently, they are considerably stiffer and need less preload, which reduces friction and allows smoother running. Crossed roller guides are also distinguished by high guiding accuracy and load capacity. Force-guided rolling element cages prevent cage creep.
Drive types
- 2-phase stepper motor for high torque even at low velocities and higher resolution
- DC motor for high velocity constancy, low vibration, and high velocities

Technology

Classical Guiding Systems
Positioners with travel ranges from several millimeters to one meter usually utilize traditional mechanical guide components such as ball bearings.

Incremental Sensors
PI uses incremental measurement systems for longer travel ranges, starting from approximately one millimeter. These sensors, which in most cases are optical sensors, achieve position resolution down to the picometer range.

Multi-Axis Positioners
Hexapod platforms are used for precision positioning and alignment of loads in all six degrees of freedom, three linear axes, and three rotational axes.

Rotating Electric Motors
Rotating electric motors such as DC or stepper motors are used in connection with screw or worm drives.
Applications

Genome Sequencing
Be it in medicine, forensics, or genetics - the genome is the key to new insights for numerous questions. The method known as sequencing-by-synthesis, which used to decipher the genome, has become faster and more precise since it was first developed — the cost has decreased, respectively. The positioning techniques employed in the microscope systems used for this purpose have also contributed to...

Adaptive Diaphragm Positioning
In radiation therapy, the individual leaves are adjusted so that the healthy tissue offers the optimum protection from the radiation.

Image Stabilization
Fast, piezo-based scanners operate with the necessary velocities in the video frequency range for image stabilization and microscanning.

Pipetting
Piezomotors are suited for pipetting with small devices and sample separations and are able to move the pipettes in the vertical direction.

Optical Coherence Tomography
Piezo actuators and drives, e.g., PILine® OEM motors, ensure the high precision and position stability required for optical coherence tomography (OCT).

Magnetic Resonance Imaging
Piezo drives are well suited for magnetic resonance therapy, because they are not influenced by strong magnetic fields.

Refractive Surgery
In refractive surgery, high-precision positioning and motion control of the laser are decisive for good results. Piezo-driven stages and tip/tilt mirror systems offer the requested precision, are dynamic and fast and thus additionally help to reduce the treatment time.
