Sinusoidal Scanning Motion Performance: Air Bearings vs. Mechanical Bearings

Application Description Most of the motion solutions we work on typically require either point-to-point positioning or constant velocity scanning motion. In these applications, customers are usually concerned with accuracy, repeatability, or velocity regulation. One special type of motion that is occasionally required is sinusoidal scanning motion. In these applications, the motion stage is expected to […]

Force & Position Control in Precision Automation

A host of applications can benefit from fast actuation systems equipped with precise metrology for controlling both force and position accurately. These include: Fast production testing of touch- and force-sensitive and haptic components; Delicate, high-speed automated assembly procedures where position vs. force is important; Testing of physical characteristics such as compliance, damping or other material […]
