What is the engraving machine?

      CNC engraving and milling machine can also be called engraving machine. It is a CNC machine tool used in optical glass, mobile phone touch screen, glass drilling, slotting, chamfering, PCB fixture, glasses engraving, small mold, copper fine carving, small parts processing, etc. The engraving machine is a machine that is driven by X, Y and Z axes and controlled by an electronic controller. It comes with a tool magazine and automatic tool changer. It is a highly automated multi-function CNC machine tool that can be used for engraving and milling. Compared with the engraving machine, the power of the spindle and the servo motor is increased, and the bearing capacity of the bed is increased, while maintaining the high speed of the spindle, and more importantly, the precision is very high. high.

       The engraving machine can process holes with a small diameter of only 0.8mm, the thickness of the glass that can be processed can reach 20mm, and a grinding head with a diameter of 50mm can be used. At present, the engraving machine is mainly used in the processing of glass panels. As far as a single equipment is concerned, the basic equipment ZDL400SKD-A produces 0.7-0.8mm thin glass. When rough machining, Φ11mm hole: about 150 holes/hour; 1.2*10.9mm groove: about 200 pieces/hour; when finishing machining, 53*107mm shape fine grinding (0.3mm allowance): about 80 pieces/hour; Φ11mm inner hole (margin 0.15mm): about 400 holes/hour; 1.2*10.9mm slot (margin 0.15mm): about 500 holes/hour. In actual production, the assembly line can split the production process, so that the production efficiency will be improved, and the yield will also be improved. Taking the data provided by the customer as an example, for glass products with a length of 107.46±0.02mm, a width of 53.06±0.02mm and a thickness of 0.8mm (including edging, drilling, slotting and other processes), 100 engraving machines can be used in 22 hours. About 250,000 pieces are produced. Overall, the dimensional accuracy of Jingdiao machined glass products can ensure ±0.01mm within 150mm and ±0.02mm within 250mm.
