The accuracy of textile machine accessories varies depending on the type of accessory, manufacturer, manufacturing process, and application scenario. Overall, the accuracy of modern textile machine accessories is relatively high. The following is a detailed introduction:
1. Precision of key moving parts: The precision requirements for key moving parts of spinning machines such as rollers, spindles, and needle fabrics are relatively high. Taking the roller as an example, it is an important component for controlling fiber motion and stretching during the spinning process. Its cylindricity, coaxiality, and other form and position tolerances are usually controlled within a very small range. Generally, the cylindricity error can be controlled within 0.005mm to ensure that the fibers are evenly stressed during the stretching process, and the spun yarn has uniform thickness and stable quality. As the main twisting and winding component of a spinning machine, the spindle's radial runout accuracy is usually required to be within 0.01mm. The stability during high-speed operation directly affects the twist and quality of the yarn.
2. Accuracy of transmission components: The accuracy of transmission components such as gears and pulleys is crucial for the smooth operation of textile machines. The manufacturing accuracy of gears generally reaches level 7 or higher, and there are strict standards for gear profile errors, pitch deviations, etc. to ensure the correctness and stability of transmission, and reduce noise and vibration. For example, the tooth profile error of high-precision helical gears can be controlled within 0.02mm, and the accumulated tooth pitch error can be controlled within 0.05mm. The outer circular runout and end face runout of the pulley also have strict requirements. Generally, the outer circular runout is controlled within 0.1mm to ensure the smoothness and reliability of the belt transmission.
3. Precision of Needle Fabric Accessories: Needle fabric is a key component of the carding machine, and the precision of parameters such as the density, height, and angle of its needle teeth directly affects the carding effect of fibers. The height error of the needle teeth is generally controlled within 0.05mm, and the angle error is controlled within ± 1 ° to ensure effective grasping and combing of the fibers, and to improve the separation and straightness of the fibers.
4. Precision differences among different manufacturers: Internationally renowned textile machinery accessory manufacturers, such as Germany's Trutzler and Switzerland's Rieter, rely on excellent manufacturing technology and strict quality control systems to produce high-precision and high-performance textile machinery accessories, and their product accuracy is often at a good level. However, some small or relatively low tech manufacturers may produce accessories with slightly lower precision, and there may also be a certain gap in product quality and stability.
5. The influence of processing technology on accuracy: Adopting excellent processing technology, such as CNC machining, precision grinding, EDM, etc., can significantly improve the accuracy of textile machine components. For example, CNC machining centers can achieve high-precision machining of complex shaped components, with machining accuracy up to 0.01mm or even higher. Precision grinding technology can achieve a roughness of Ra0.1 μ m or less on the surface of accessories, further improving the accuracy and surface quality of accessories.
Modern textile machinery accessories are constantly pursuing higher precision to meet the textile industry's demand for efficient production. With the continuous advancement of manufacturing technology, the accuracy of textile machine accessories will continue to improve.
