Today, there are many industries that depend on linear stage devices for a wide range of programs and industrial applications. This is a device that offers unparalleled accuracy and convenience when it comes to applications belonging to nano-positioning and micro-positioning fields.
The Principle of Work
All products are constructed uniformly. They consist of two things – a base and a platform. The parts of the linear stage that include a base and a platform are linked by linear bearing or guide in such a way that the platform is restricted to any type of linear motion with regard to the base. It is always the platform the device that moves in reference to its base.
Precision linear stage only exhibits one degree of freedom, i.e., the motion in the system is restricted to only one axis by the system guide. The system allows for effective motion translation along any one axis in the overall three-dimensional space. Whether it is the X-axis, Y-axis, or the vertical Z-axis, the motion is performed in any one translation axis.
Most of the times, the sliding motion created in the system has been interchangeably referred to as a linear slide. However, in technical parlance, the linear slide is only a component of a linear stage and is usually referred to a linear motion bearing. This device is a miniature part of a large motion control system or is typically also addressed as a small component that constitutes a part of a linear-moving stage. Its main role is to perform the task of constricting a specific section of the system to one single motion axis.
Today, with increasing technologies and inventions in every field, there are hundreds to thousands of industrial applications that require motorized precision linear stage and precision control devices for fulfilling multifarious industrial and commercial needs. Therefore, these devices are mainly found in fields such as metrology, microscopy, laser, scanning, inspection, water scribing, biotechnology and many more.
Most of the times, these stages are employed in applications that amount to high speed, accuracy, acceleration, and repeated use over extensive work hours. Nonetheless, there are a few features that determine that a linear stage device is truly a state-of-the-art machine. So let us see below some of the most defining factors for the same.
True Factors that Define the Performance of a Linear Stage
- The stage should offer precise trajectory control.
- It should provide superior accuracy, performance, and repeatability.
- The stages are based on the stepper or servo motors along with linear bearings. Hence, all these components must function smoothly and flawlessly.
- For super-complex applications, some manufacturers also offer linear stages in sub-micron precision.
- In addition, the most crucial factor to consider is the amount of friction the device creates in the stage when it is put to use.
When you plan to invest in a precision linear stage device, the most important perhaps, the foremost factor you must decide upon is the distance you want to cover up or want the stage to travel during the application. Based on this note, handful of factors such as accuracy, precision, minimum rise in motion, and repeatability are equally determined.
