What is an efficient job to make ultra clear and precise cross line alignment for all stone milling works? It might be processing at various work distances and lighting occasions, not limited by long distance or high height in various workshop environments, 445nm blue crosshair laser module makes sure of easy reaching, good direction and high precision two perpendicular blue lines generation with accurate 90 degrees. 445nm blue laser light has significantly higher penetration than red light in the high-dust environment generated by stone polishing. The 445nm blue cross laser alignment features a metal heat dissipation system and an anodized aluminum alloy shell, with a temperature resistance range of -20℃ to 60℃. Even under high-temperature vibrations from the polishing equipment, the blue crosshairs remain clear and without blurring.
Usually 445nm blue crosshair laser module applies an import 445nm blue laser diode and a qualified glass coated lens with 10, 15 and 110 degree fan angles. After its easy connects with 5V, 9V or 12V 1000mA AC/DC adapter, it enables long term lasted blue vertical and horizontal lines generation for both of long time and long distance use. Basically it is designed with a metal heat sink cooling system and APC, ACC driving circuit board, it keeps work with constant blue vertical and horizontal lines generation within 24 hours, not affected by increasing temperature and serious electric current impact as well. This blue cross laser alignment is suitable for batch stone milling scenarios conveniently.
In practical stone milling works, 445nm blue crosshair laser module maintains high straightness and high fineness cross line projection, replacing the coarse calibration of traditional measuring tapes and ink lines. This significantly reduces human visual error, keeping dimensional deviations in stone polishing to a minimum. After the selection of output power and optic lens fan angle, and properly adjusted blue cross line thickness and projecting direction, 445nm blue cross laser alignment provides a noncontact projection method, which will not leave marks on easily scratched stone surfaces such as marble and jade, avoiding additional repair procedures. Furthermore, owing to its ultra compact size tube design, it can be easily installed on angle grinders, fully automatic grinders, and other equipment, compatible with various models, and simple operation. Compared to traditional marking, it significantly reduces pre-grinding setup time and lowers construction costs.
General applications in stone milling works:
Contour Polishing Positioning: When polishing irregular contours of marble, granite, and other stones, a blue crosshair is projected to mark the contour baseline and center origin, assisting workers or automated equipment in controlling the polishing trajectory and avoiding contour deformation;
Plane Leveling Baseline: When polishing the surface of stone slabs for leveling, the blue cross lines can project a plane reference surface, visually displaying the height difference of the stone surface and guiding the polishing equipment to accurately handle protruding parts;
Joint Surface Polishing Alignment: Before splicing stone curtain walls and floor tiles, the crosshair emitted from a 445nm blue cross line laser module is used to align the splicing ends, marking the polishing thickness and flatness standards to ensure uniform gaps and a smooth surface after splicing;
Carving / Texture Polishing Calibration: When finely polishing stone reliefs and patterns, the blue alignment laser is used to calibrate the pattern proportions and depth references, avoiding over-polishing or under-polishing in certain areas and maintaining texture consistency.
