1. The machine is professional automatic equipment for marking and drilling of angle steel. 2. With CNC and servo motor it achieves high efficiency and stable working accuracy. 3. The main hydraulic, pneumatic and electrical elements are all imported from Germany, Japan, Italy, South Korea etc. 4. Rotation speeds of all spindles are stepless adjustable realized by frequency converter, Feeding speed is also stepless adjustable realized by flow control valves. Rapid feed, working feed and rapid back of drilling spindles can be automatically converted. 5. There is a marking unit in the drilling line. Marking stadia can be preset conveniently 6. Cooling system with automatic circling is adopted to prolong the life of drills. 7. Easy programming. The operator can use the automatic data from software directly. Friendly computer interface can show workpiece's figure, easy for operation. Machining program can be generated automatically in computer as long as operator inputs the dimensions of workpiece, which can be conveniently stored, called up, displayed and communicated according to the different workpieces. 8. Direct transfer of CAD/CAM. 9. Equipped with self-diagnostic function.Model Number APL-2532 Function Drilling & Marking Angle size 40x40x10~250x250x32mm Material Q235A or16Mn Nominal marking force 1040kN NO. of character groups 1 Dimension of character 14x10x19(According to demands of customers) NO. of drills on each side 3 Main shaft speed 180-560/(r/min)(stepless adjustable) Diameter of drilling hole Φ 17.5~Φ40(mm) Stadia adjustment 40-280(mm) NO. of CNC axis 3 Angle steel feeding speed 40m/min Overall diamensions 29x8.9x2.5(m) Net weight 16.5(t)
