DZC2525 / 2 DZC3030 / 2 DZC4040 / 2 DZC5050 / 2 DZC6060 / 2 DZC8080 / 2 CNC gantry drilling, are all mobile gantry CNC surface drilling. Mainly used in industry, flanges, plate heat exchangers and tube processing power, petroleum, chemical, boiler, etc., can save one by one crossed the line of work. Just enter the correct CAD design drawings, you can achieve continuous two-spindle automatic drilling, CNC processing, high efficiency, high precision, easy programming, simple operation. The large gantry drilling belongs mobile gantry drilling, reducing the bed length, saving floor space. Bed, beams with steel plate welded structure, by artificial aging treatment, accuracy and stability. Gantry structure optimized design make the machine stiffness is greatly improved, can guarantee a large amount of cutting. Workbench layout has several transverse T-shaped grooves for clamping fixture and workpiece.
