Kate HTPM Linear Guide Lubrication Unveiled

Today, we will introduce the lubrication device of linear guides. 1. What is the lubrication of linear guides? Lubrication of linear guides refers to the use of lubricants in linear guide systems to reduce friction, prevent wear, reduce noise, and improve the motion accuracy and service life of the guides. The lubricant forms a thin film between the guide rail and the slider, avoiding direct metal contact, thereby reducing friction and wear. 2. What are the functions of linear guide lubrication? 1. Reduce friction: The lubricant forms a protective film between the guide rail and the slider, reducing the coefficient of friction. 2. Prevent wear: Avoid direct metal contact and reduce wear. 3. Reduce noise: The lubricant can absorb vibration and reduce noise during movement. 4. Improve accuracy: Reducing friction and wear helps maintain the accuracy of the guide's movement. 5. Extend service life: Good lubrication can significantly extend the service life of the guide system. 3. What are the lubrication methods for guides? 1. Manual lubrication: Regularly apply grease or lubricating oil manually, suitable for low-speed, light-load applications. 2. Automatic lubrication: The automatic lubrication system supplies lubricant at regular intervals and quantities, suitable for high-speed, heavy-load, or continuous operation applications. 3. Oil lubrication: Use lubricating oil, suitable for high-speed, high-precision applications. 4. Grease lubrication: Use lubricating grease, suitable for low-speed, heavy-load, or applications requiring long-term lubrication. 4. How should lubricants be selected? 1. Lubricating oil: Good fluidity, suitable for high-speed, high-precision applications. Grease is generally replenished every 100 km of operation or the lubrication frequency is adjusted according to the specific situation. When there are factors such as pollution, vibration, and influence, the lubrication cycle should be shortened accordingly. 2. Lubricating grease: High viscosity, suitable for low-speed, heavy-load, or applications requiring long-term lubrication. It is recommended that customers use lubricating oil with a viscosity of ISO VG32~150. 5. What are the precautions for using lubricants? 1. Appropriate lubrication: Too much or too little will affect performance. Too much may cause leakage, while too little will increase friction and wear. 2. Cleaning: Clean the guide rail and slider before lubrication to avoid impurities affecting the lubrication effect. 3. Regular inspection: Regularly check the lubrication status and replenish or replace the lubricant in time. The small lubrication device is closely related to the service life of the guide rail. Therefore, selecting the appropriate lubricant and lubrication method and performing regular maintenance can effectively improve the operating efficiency and reliability of the guide system.

Introduction to THK linear guideway false rails

A false rail for a slide is an attachment used for linear guides, usually made of plastic or metal. It is matched to the size of the slide. The following figure shows two types of false rails. The black one is commonly used with THK linear guide slides, and the green one is used with HIWIN linear guide slides. The color matching is based on the brand's own usage. So what is the function of a false rail? Let's introduce it below. Easy Installation: When installing the slide onto the guide rail, the false rail acts as a guide to prevent the slide from deviating from the track during installation, ensuring accurate and smooth installation. As can be seen from the following figure, when installing the slide, do not remove the false rail. Instead, push the slide along the guide rail, and the false rail will slowly come out, playing a guiding and protective role at the same time. Protection of Balls: The false rail prevents the balls from falling or being damaged due to vibration or collision during transportation or storage, protecting the integrity and performance of the balls. Improved Stability: The false rail increases the contact area between the slide and the guide rail, improving the stability and load-bearing capacity of the slide, and reducing shaking and vibration during movement. Reduced Friction: The false rail forms a protective layer between the slide and the guide rail, reducing friction and wear between the slide and the guide rail, improving the service life and performance of the slide. Easy Maintenance: The false rail facilitates maintenance and upkeep of the slide, such as cleaning and lubrication, extending the service life and performance of the slide.

THK Linear Guideway Professional Terminology Introduction

Linear guides are used in many industries. Today, we will introduce some keywords about guides, taking THK guides as an example. 1. What does the accuracy of THK guides refer to? Guide accuracy refers to the precision of the motion trajectory of the moving guide along the supporting guide, specifically manifested as the linearity of the linear motion guide and the roundness of the circular motion guide. (Whether the linear motion is straight, and whether the circular motion is round) 2. What is guide preload? Guide preload refers to applying a certain force to the bearings or sliders during guide installation to generate pre-pressure between them and the guide. Appropriate preload can eliminate the clearance between the rolling elements and the guide, reduce deformation when the guide bears a load, provide more stable support for high-precision processing or equipment that bears relatively large cutting forces, and reduce processing errors. Reasonable preload can make the contact between the rolling elements and the guide more uniform, reducing local wear. However, excessive preload will increase friction and heat generation, which may reduce the service life. It can reduce the jumping and vibration of the rolling elements, making the slider move more smoothly on the guide. For high-speed motion or frequent starts and stops, the effect of improving motion accuracy is more significant. Preload is also classified into levels, such as light preload and medium preload, which can be selected according to the needs of your equipment.

Introduction to THK ball screws

When discussing lead screws, we can consider aspects from the brand (THK, HTPM), whether imported or domestic, to the specific model, size, and application. But what exactly defines a lead screw? Let's explore: Lead screws are transmission components that convert rotary motion into linear motion, or vice versa. Components of a Lead Screw: Screw: A slender shaft with helical grooves, forming the main part of the lead screw. Nut: Mates with the screw, containing corresponding helical grooves, allowing axial movement along the screw. Ball Bearings (in some lead screws): Located between the screw and nut, these reduce friction through rolling, improving transmission efficiency and precision. Other Components: Such as reverse mechanisms, dust covers, and lubrication systems, which ensure proper operation and longevity. Working Principle: A motor drives the lead screw to rotate. The nut on the screw shaft, driven by the rotating threads, achieves linear reciprocating motion, converting the motor's rotational torque into the linear driving force needed for equipment movement. Applications: Machine Tools: Used for workpiece feed, tool movement, etc. Automated Equipment: Such as robots and automated production lines, for precise positioning control. Aerospace: Used in aircraft attitude control, engine adjustment, etc. Automotive: Used in automotive steering systems, suspension systems, etc. Medical Devices: Such as CT scanners and MRI machines, for precise scanning and positioning.
