Technical Parameters Dimensions: 200150mm range: 360355290mm weight: 13KG Lifting height: 15mm Marking speed: 50mm/s Marking depth: 0.05-1mm Needle hardness: 93HRA Needle distance: 0.5-1mm Voltage power: 110V 400W Working principle: After being energized, the electromagnetic coil rotates at high speed to generate suction thrust, which causes the needle to vibrate at high frequency, impact the workpiece, and hit a dot matrix. At the same time, the computer controls the needle movement, so that the dot matrix forms lines to form characters and graphics on the workpiece. Electric marking machine dedicated for marking on the nameplate and nameplate; 2. Adopt electric marking method without air compressor (air pump), easy to use; 3. Applicable to all metal or.
