During the customization process of quartz plates, ensuring precision is of vital importance, especially in high-precision application fields such as optics, semiconductors, and laser technology. The high-precision requirements for quartz plates involve multiple aspects, including material selection, processing technology, equipment accuracy, detection methods, and quality control, etc. The following will explore in detail from multiple aspects how to ensure the customization accuracy of quartz plates.

The high precision of quartz plates primarily depends on the quality of the material. Quartz is a material with excellent optical, thermal and mechanical properties, but its performance is affected by the purity, uniformity and internal defects of the raw materials. Therefore, when customizing quartz plates, quartz materials with high purity and low impurity content should be selected. During the material pretreatment stage, quartz materials need to undergo strict screening and testing to ensure that there are no internal defects such as bubbles, cracks, and impurities.

The processing technology of quartz plates directly affects their precision. Common processing techniques include cutting, grinding, polishing and coating, etc. The following are the key control points of each link.

(1) Cutting

Cutting is the first step in quartz plate processing and requires the use of high-precision cutting equipment, such as diamond wire cutting machines or multi-wire cutting machines. During the cutting process, the cutting speed, pressure and the use of coolant must be strictly controlled to reduce the thermal deformation and surface damage of the material. The cut quartz plates should have uniform thickness and smooth edges.

(2) Grinding

Grinding is to remove the surface damage produced during the cutting process and further control the thickness and flatness of the quartz plate. When grinding, appropriate abrasives and grinding fluids should be selected, and the grinding pressure and speed should be strictly controlled. High-precision grinding equipment (such as double-sided grinding machines) can ensure that the parallelism and surface roughness of both sides of quartz plates meet the requirements.

(3) Polishing

Polishing is a key step in improving the surface smoothness of quartz plates. The surface roughness of optical-grade quartz plates is usually required to reach the nanometer level. During the polishing process, high-precision polishing equipment and polishing liquid must be used, and the polishing time and pressure must be strictly controlled. The polished quartz plate should have a uniform luster and a scratch-free surface.

(4) Coating

In some applications, quartz plates need to undergo coating treatment (such as anti-reflection films, reflective films, etc.). The coating process must be carried out in a high vacuum environment, and the thickness and uniformity of the film layer must be strictly controlled. The quartz plates after coating need to undergo optical performance testing to ensure they meet the design requirements.

3. High-precision processing equipment

The high-precision processing of quartz plates cannot do without high-precision processing equipment. The precision of the equipment directly affects the size, shape and surface quality of the quartz plate. For instance, the precision of high-precision CNC machine tools, laser cutting machines, polishing machines and other equipment should reach the micrometer or even nanometer level. In addition, the stability of the equipment is also of great significance. Regular calibration and maintenance are required to ensure its long-term stable operation.

4. Detection methods and quality control

Detection is a line of defense to ensure the accuracy of quartz plates. The inspection of high-precision quartz plates includes size inspection, surface quality inspection and optical performance inspection, etc. In terms of quality control, a strict quality management system needs to be established to monitor and record each process. For high-precision quartz plates, it is recommended to adopt full inspection or sampling inspection methods to ensure that each quartz plate meets the precision requirements.

5. Conclusion

Ensuring the precision of custom-made quartz plates requires comprehensive control from multiple aspects such as material selection, processing technology, equipment precision, and detection methods. Through strict process management and quality control, the performance stability and reliability of quartz plates in high-precision applications can be ensured.
