Description: Pneumatic marking machine-combined with computer, electrical and precision machinery techniques. It is industrial marking equipment which can make logo (character, VIN code, serial number, date and graph) on workpiece (metal or no-metal materials) permanently. Computer controls the pin to move in X-Y plane and mark the logo on the certain location of workpiece. Main characters: Marking contents: all kinds of logos (characters, serial numbers, VIN codes, dates and metal or non-metal material (hardness under HRC60) High stability labor controls engine case Computer part adopted 15" LCD screen Streamline form cabinet designing, ultra liquid crystal display, which with fashion mode Suitable for signing on various metalloid and stone canaled spare parts Supports flat surface marking Marking contents could be saved automatically and not be destroyed due to the electric-break Supports Windows98/XP/ME Supports multi-kinds fond: MG Fond, SHX Fond in Auto CAD, CHR in Borland, TTF in Windows Supports DXF format graph from CAD, Corledraw The design of block-out controlling cabinet benefits for damp-proof, dust-proof, shake-proof, it could be used in the wicked working condition Main tech-specifications: Marking speed: 30-40mm/s Hitting frequency: 300Hz Marking depth: 0.1-1mm (according to workpiece material) Marking accuracy: 0.02mm Marking scope: 100 x 80mm (supply scope is allowed) Pinhead hardness: HRA92 Workpiece hardness allowed: ≤HRC40 Inputting air pressure: 0.3-0.6MPa Power consumption: ≤500W Voltage: AC220V10%, 50Hz Working temperature: 0°C-40°C Relative humidity: ≤90%Applications: It is adequate for marking characters, serials numbers and VIN codes on automobile or bodywork of motorcycles, car frames, automotive chassis, connecting rods, engines, cylinder various stepper motors and mechanical parts, machine tools, metal pipes, pump bodies, valves, fastening pieces and various hard plastic products.
