Multi Axis Linear Stages Are Ready for Delivery to UK

Multi-axis linear stages achieve high positioning accuracy and repeatability through a combination of design features, components, and control systems. How do multi-axis linear stages achieve high positioning accuracy and repeatability?

Here are some key factors that contribute to their precision: 1. Mechanical Design: Multi-axis stages are built with precision in mind. They incorporate high-quality materials and construction techniques to ensure rigidity, stability, and minimal play or backlash in the mechanical components. This reduces unwanted vibrations and ensures accurate positioning. 2. Linear Guides and Bearings: These stages utilize high-precision linear guides and bearings to provide smooth and precise linear motion. These components minimize friction and ensure consistent movement, contributing to accuracy and repeatability. 3. Drive Mechanisms: The choice of drive mechanism plays a crucial role in achieving accuracy. Multi-axis stages can use various drive systems such as stepper motors, servo motors, or linear motors. These drive mechanisms are selected based on the requirements of the application, with considerations for speed, torque, precision, and smoothness of motion. 4. Feedback Systems: To achieve precise positioning, multi-axis stages often incorporate feedback systems such as linear encoders or optical scales. These systems provide real-time position feedback to the control system, allowing for closed-loop control. Feedback enables the control system to correct for any errors or deviations, resulting in higher accuracy and repeatability. 5. Control Systems: Multi-axis stages are typically integrated with control systems that allow precise motion control. Advanced control algorithms, such as PID (Proportional-Integral-Derivative) control, are employed to optimize the positioning accuracy and reduce errors. The control systems can be manual, computer-based, or even programmable, depending on the complexity and requirements of the application. 6. Calibration and Compensation: Manufacturers of multi-axis stages often perform calibration procedures to ensure accurate positioning. Calibration involves mapping the actual position of the stage to the commanded position and applying compensation techniques to correct any deviations or non-linearities. This calibration process further enhances the accuracy and repeatability of the stages. 7. Environmental Considerations: Multi-axis stages are designed to minimize the impact of environmental factors on positioning accuracy. They may incorporate features such as dust seals, temperature compensation, or vibration isolation to mitigate the effects of temperature variations, contaminants, or external disturbances. By combining these design features, high-precision components, feedback systems, advanced control algorithms, and calibration procedures, multi-axis linear stages can achieve the high positioning accuracy and repeatability required for demanding applications in fields such as microscopy, metrology, semiconductor manufacturing, and precision assembly.

How to adjust the preload of ball screw nut. Ball screw nut pair is a high-precision transmission device. It uses rolling friction screw instead of sliding friction screw, which has the advantages of small wear, high transmission efficiency, stable transmission, long service life, high accuracy and low temperature rise. Select high-quality screw to identify titanium Hao. Because the ball screw nut pair has the outstanding advantages of small motion friction and easy to eliminate transmission clearance, it brings great benefits to the performance improvement of electromechanical integration system. Pre tightening is to prevent the ball from slipping. The self-locking property of the ball screw nut pair is poor, which can be said to be absent. It is easy to fall off without pre tightening. https://youtube.com/shorts/ctaMxDnmOC8?feature=share There are four common methods for ball screw preloading: - Double nut gasket type pre tightening The mechanism of this method is simple and reliable. Good rigidity and most widely used. The form of adding gasket between the double nuts can be adjusted in advance by a professional manufacturer according to the user's requirements. It is very convenient to unload when using. - Double nut threaded pre tightening Use the external thread on one nut to adjust the relative axial position of the two nuts through the round nut to achieve pre tightening. - Double nut tooth difference pre tightening On the flanges of the two nuts, cut out the gears with a tooth number difference of 1. The two gears mesh with the corresponding internal gear rings at both ends. The internal gear rings are fastened on the nut seat with screws. By rotating one of the nuts, the mutual positions of the two nuts are changed to adjust the clearance and apply the preload. - Single nut variable lead self preloading The internal thread raceway of the nut will produce a lead sudden change on the middle circle, so that the balls at the left and right ends will be axially displaced after assembly to realize pre tightening. The purpose of eliminating the axial clearance of the ball screw nut pair is to increase the preload and reduce the empty stroke in the reverse direction, so that there is no reverse dead zone, and improve the transmission rigidity and transmission accuracy. Not all ball screws(in Linear Translation Stages) are pre tightened, mainly according to the accuracy requirements. Generally, the pre tightening accuracy is high and the load capacity is large. The pre tightening is graded. The selection is based on the use requirements. You can check the samples of different brands for details. Read the full article

It is widely used in the positioning, transfer, handling, inspection, dispensing, welding, cutting, etc. of LCD panels, semiconductors, home appliances, daily chemicals, automobiles, batteries and other fields. Related Knowledge: The main features of the application of the ball screw in the module. The ball screw is the most commonly used transmission element in machine tools and precision machinery. Its main function is to convert rotary motion into linear motion, or convert torque into axial repetitive force, and it has both high precision, reversibility and high Features of efficiency. Ball screw is also called ball screw and ball screw. 1) High positioning accuracy The ball screw pair realizes rolling friction between the nut and the screw by ball rolling. The motion of the rolling linear guide is realized by rolling of the steel ball. The friction resistance of the guide pair is small, the difference between dynamic and static friction resistance is small, and no crawling occurs at low speeds. . High repeat positioning accuracy, suitable for moving parts that frequently start or change directions. 2) Less wear Due to the low frictional energy consumption of rolling contact, the friction loss of the rolling surface is also reduced correspondingly, so the rolling linear guide system can be in a high-precision state for a long time. At the same time, the use of lubricating oil is also very small, which makes it very easy to design and use and maintain the lubrication system of the machine tool. 3) Long life For the nut of the ball screw pair, the screw hardness reaches HRC58-62, and the ball hardness reaches HRC62-66, and there is rolling friction between them, so higher fatigue life and accuracy life can be achieved. 4) Adapt to high-speed movement Due to the low friction resistance of the rolling linear guide module, the required power source and power transmission mechanism can be miniaturized, and the driving torque can be greatly reduced. It can realize high-speed linear motion and improve the working efficiency of the machine tool. 5) Strong carrying capacity Rolling linear guides have good load-bearing performance and can withstand forces and moment loads in different directions, such as up, down, left, and right directions, as well as bump moments, rocking moments and swing moments. Therefore, it has good load adaptability. 6) Easy to assemble and interchangeable The ball screw and rolling guide are interchangeable. As long as the slider or the guide rail or the entire rolling guide pair is replaced, the module can regain high precision. 7) Micro and high-speed feed can be realized The ball screw pair will not produce such as sliding phenomenon, can realize the micro-feed; as long as the feed pulse is small enough, the ball screw pair can realize the micron-level feed. Because of the low heat generation of the ball screw pair and the ability to manufacture a large lead screw, high-speed feed can be achieved. Read the full article
