  • Case Studies [Precision Positioning Switches] : Correct the Deviation of Printing Drums in Micron Increments
    Metrol's "Precision Positioning Switches" are widely adopted in various applications in order to control positions in micron increments. One of them is "positioning of the printing drums of rotary press". Significant improvements in printing quality can be realized by correcting a slight deviation
  • Telescope Positioning Using Tiltmeters
    Accurately positioning large and small telescopes. has always been a difficult problem. Jewell. Instruments precision tiltmeters provide a simple. and effective solution. Tiltmeters are unlike. conventional systems that measure telescope. position using rotary encoders coupled to the. telescope
  • "Micropositioning" - Classical Precision Positioning Technologies Still Going Strong
    Traditional linear and rotary "micropositioning" stages are based on servo and stepper motor-driven leadcrews and ballscrews and mechanical bearings. They are classical components for precision motion control applications, spanning from lab-automation to industrial assembly and inspection.
  • Pros and Cons of Absolute vs. Incremental Rotary Encoders
    encoder is generally more susceptible to electrical noise. Image 1: Incremental Disc Applications with higher requirement regarding precision often rely on absolute rotary encoders. Especially when it is complicated or not possible at all to return to the reference point.
  • Positioning Stages and Gantries - New Trends in Integration Approaches
    There's demand for motion designs offering simplicity or turnkey operation, so component suppliers are now doing much more integration for OEMs and plant engineers. Nowhere is this more evident than in the way today's positioning stages, rotary tables, and gantry setups are built. These quickly
  • An Innovative Cabling Concept Improves Reliability for Multi-Axis Stage Systems (.pdf)
    Manufacturers of precision positioning systems are often faced with applications requiring multi-axis stage systems. Usually an object has to move in two, three or more degrees of freedom (DOF) including linear movements, rotary movements, tilt and/or lifting operations.
  • Actuator Tips
    Stepper motors are commonly used to translate motion from rotary to linear. Selecting the right combination of electrical and mechanical components is complicated by the various options for precision positioning systems. This brief will review key criteria for successful stepper linear actuator
  • 5-Axis Air Bearing Optical Measurement Metrology Platform
    ABTech Manufacturing creates five-axis platform for. nanometer/sub-arc second processing around its. ultra-precision air bearings and Renishaw SiGNUMTM. position encoders. When a leading manufacturer of CNC optical. manufacturing technology needed ultra-accurate and. stable positioning for a new
  • Carbon Fiber Placement Application
    systems with Zero-backlash ensure that the axes synchronize and the part is compliant. Due to the reducer pinion and rack precision, the position is controlled by an encoder on the servo-motor eliminating the need for expensive linear scales.
  • When to Use Air Bearings and Mechanical Bearings
    in these situations. An air-bearing stage is a rotary or linear positioner that floats on a cushion of air, using one of several preloaded mechanisms, nearly eliminating mechanical contact and thus wear, friction, vibration, and hysteresis effects. These are the most common indicators that an air-bearing stage
  • Air Bearings: When to Use and When to Avoid in Your Motion Application
    . An air-bearing stage is a rotary or linear positioner that fl oats on a cushion of air, using one of several preload mechanisms, nearly eliminating mechanical contact and thus wear, friction, and hysteresis effects. These are the most common indicators. that an air bearing stage might be the right choice
  • Motion Control and Encoder Technology: A Tutorial
    Sensors and encoders are used everyday in manufacturing environments and high precision equipment to monitor the proximity or presence of an object, as well as the position, distance, direction, and speed of rotating equipment. Encoders enable design engineers to control motion by providing
