What Is Grating Used For? Key Applications From A Chinese Supplier's Perspective

When it comes to precision measurement and motion control, gratings stand as unsung heroes in countless industrial and technological workflows. As a trusted Chinese supplier specializing in high-quality grating solutions, we often get asked: “What is grating used for?” The answer lies in its unique ability to convert mechanical displacement into measurable optical signals, enabling ultra-high precision in critical applications. From advanced manufacturing to cutting-edge medical equipment, gratings are integral to industries that demand accuracy, reliability, and consistency. In this post, we’ll break down the core applications of gratings, highlighting how Chinese suppliers tailor these components to meet global industry standards.

One of the most prominent uses of gratings is in industrial manufacturing, particularly in CNC machine tools. Modern manufacturing, whether for automotive parts, aerospace components, or precision machinery, relies on CNC systems to achieve tight tolerances—often within ±0.05mm or even nanometers. Gratings, especially grating scales, serve as the “precision eyes” of these machines by real-time feedback of tool and workpiece position. Chinese suppliers produce high-resolution grating scales that integrate seamlessly with CNC systems, ensuring accurate tool path adjustments. For example, in aerospace engine turbine blade manufacturing, our gratings help maintain the strict dimensional requirements of blade profiles, directly impacting engine efficiency and safety. This application not only improves product quality but also reduces scrap rates, a key advantage for manufacturers seeking cost optimization.

The semiconductor industry is another sector where gratings play a pivotal role, requiring nanoscale precision. In lithography machines, the core equipment for chip manufacturing, gratings enable ultra-precise positioning of the lithography head and wafer. As Chinese suppliers, we specialize in gratings that support 7nm and smaller chip manufacturing processes, ensuring stable and accurate exposure of circuit patterns. Our products are also used in wafer handling, cutting, and packaging equipment, where consistent positioning prevents costly chip damage. With the global semiconductor industry’s growing demand for miniaturization, Chinese grating suppliers have invested in R&D to produce gratings with lower periodic error (≤±10nm) and higher speed capabilities, meeting the sector’s most rigorous requirements.

Gratings are also indispensable in medical equipment, where precision can mean the difference between accurate diagnosis and effective treatment. In CT scanners, gratings enhance imaging precision by controlling the rotation of the scanner gantry, delivering clearer images of internal organs and tissues. Chinese suppliers have developed specialized gratings for medical applications, such as those used in radiation therapy equipment, which ensure the radiation beam is accurately targeted at tumors while minimizing damage to healthy tissue. Our medical-grade gratings comply with international safety standards, making them a reliable choice for global medical device manufacturers. Additionally, in genetic sequencing equipment, micro-positioning systems equipped with our gratings enable precise sample handling, accelerating research and diagnostic processes.

The aerospace and defense sectors also rely heavily on gratings for navigation, control, and姿态 measurement. Aircraft and spacecraft require precise positioning systems to ensure stable flight and accurate navigation, and gratings provide the high-resolution displacement data needed for these systems. Chinese suppliers produce ruggedized gratings that can withstand extreme environmental conditions—such as high temperatures, vibration, and radiation—making them suitable for aerospace applications. From missile guidance systems to satellite attitude control, our gratings contribute to the reliability and performance of critical defense and space technologies. We also collaborate with aerospace manufacturers to customize gratings for specific mission requirements, balancing precision with durability.

Beyond these core industries, gratings find applications in metrology and testing equipment, such as coordinate measuring machines (CMMs) and laser interferometers. CMMs use gratings to measure the three-dimensional dimensions of workpieces with exceptional accuracy, ensuring compliance with design specifications in industries like automotive and electronics. Laser interferometers, on the other hand, utilize gratings to measure small displacements, helping calibrate precision machinery and detect positional errors. Chinese suppliers offer gratings optimized for these testing applications, with high signal stability and low noise to ensure reliable measurement results. We also provide technical support to help customers integrate our gratings into their testing systems seamlessly.

As Chinese suppliers, we understand that the use of gratings varies by industry, which is why we focus on customization and quality control. Our production processes adhere to ISO standards, and we use advanced materials—such as high-grade glass and metal alloys—to enhance grating durability and performance.
