Straightedge is the length standard of optical measuring instruments, and is widely used in instruments for measuring length such as tool microscopes, length measuring instruments, and measuring machines. General rulers include plastic rulers for students, stainless steel rulers for engineering, and aluminum rulers. Today we are talking about the black effect on the ruler made of alumina, stainless steel and other materials, so it is necessary to use our MOPA laser marking machine. The principle of aluminum oxide skin laser marking machine: using computer control, using high-tech laser technology and high energy density laser to laser process the workpiece, through the evaporation of surface materials, the material reveals its true color, thus leaving a permanent mark way. Features of alumina scale laser marking machine: This equipment has the characteristics of free maintenance, no consumables, and no wearing parts! Choose the professional marking software in the industry, which has powerful functions, graphic alignment and red light preview functions. It can mark various barcodes and graphic codes, and has the function of reverse printing, which fully meets customer requirements; at the same time, it is compatible with files output by CORELDRAW, AUTOCAD, PHOTOSHOP and other software. Support PLT, PCX, DXF, BMP and other files, directly use SHX, TTF fonts, support automatic coding, serial number, batch number, date, barcode, two-dimensional code labeling. Difficulties of aluminum oxide ruler laser marking machine: Since the length of the ruler is generally 33CM or even longer, a multi-functional marking table (that is, equipped with a cross-moving platform): this table is specially designed for flat and cylindrical workpieces Designed for flexible marking. The vertical pitch angle can be adjusted by 90 degrees to achieve flexible marking of round pipes and ring workpieces. The horizontal movement distance is 1M or more. It can precisely mark various calipers and gauges. Other advantages of aluminum oxide ruler laser marking machine: Nearly perfect marking quality: the laser mode of the basic model provides excellent beam quality; vibration-type high-precision marking head, good marking effect, repeatable processing; high-precision, The meticulous light spot ensures the perfect marking result; the marking process is non-contact, and the marking effect is permanent; the maximum marking speed of 7000 mm/s improves the processing efficiency. Low operation and maintenance costs: the overscale marking machine has a long service life. The equipment has good stability and is maintenance-free for 100,000 hours; the electro-optical conversion rate is high, saving electricity; the air-cooled system is adopted, and there is no external cooling equipment; the ruler laser marking machine is easy to operate.
