(1) With the continuous improvement of the quality requirements of Optical Table and the continuous improvement of products by many research institutes, the optical platforms currently developed have a wide variety of models and the quality is uneven. Therefore, before purchasing products, the China Linear Stage Factory must first Conduct a certain understanding, such as the nature of the enterprise, understanding of comprehensive capabilities, quality standards, process routes, after-sales service capabilities and attitudes. The second is the understanding of the product, such as its materials, processing accuracy, vibration isolation effect, the overall rationality of the product, the surface of the platform is fine, the surface treatment process, the overall aesthetics.
(2) Don't pay too much attention to one or two parameters of the product. You should understand the whole product and conduct certain tests. For example, important parameters in the optical platform such as flatness, platform irregularity, natural frequency, amplitude, working pressure and maximum load should be thoroughly understood and tested. In this way, you can choose the optical platform you want to buy based on some important parameters of the product.
(3) When the optical platform is installed and used after purchase, the installation and commissioning must be in place by the manufacturer. After installation, first check whether the support leg connection of the optical platform is fastened, whether the whole platform is shaken under normal external force, the platform level is adjusted in place, and then the factory inspection report provided by the manufacturer is checked. The qualified enterprise can request the actual on-site inspection of the manufacturer. . The natural frequency of the automatic pneumatic precision vibration isolation optical platform should be:
Vertical direction: no load: 1.2~2.0 Hz; full load: 1.0~1.8 Hz;
Horizontal direction: no load: 1.2 ~ 1.8 Hz; full load: 0.8-1.6 Hz;
Horizontal, platform table flat tolerance 0.05 ~ 0.10 mm / m2;
The surface of the platform is treated with Mildy texture, and the roughness is less than 1.6 μm;
All exposed surfaces of the platform are smooth and smooth, and the bottom surface is sprayed with rust-proof paint. The lacquer surface is bright and flat without dents; the sharp edges are chamfered; the whole exterior is neat and elegant. In addition, during the use of the platform, the surface should be free of corrosive liquids such as water stains. If it is cleaned with clean paper towels and cloth in time, the air compressor should be regularly inspected and refueled. The platform level is placed every 6 It should be re-adjusted after the month.
