GD4250 Double Column Band Sawing Machine

  • Heavy Metal Material Blanking Workshops

    Specialized in high-precision cutting of large-diameter carbon steel, alloy steel, stainless steel round bars and square steels, as well as thick steel plates and seamless steel pipes. The double-column rigid structure ensures stable sawing for raw material blanking before forging, CNC machining and mechanical part production.

  • Engineering & Mining Machinery Manufacturing

    Ideal for blanking blanks of heavy equipment core parts such as excavator boom shafts, loader axle housings, mining crusher bearing seats and conveyor roller shafts. Hydraulic double-clamp prevents workpiece displacement during sawing, meeting the blanking requirements of high-strength alloy steel parts with strict verticality of cutting surfaces.

  • Steel Processing & Trading Centers

    Suitable for batch cutting of various metal profiles (round bar, square bar, angle steel, H-beam) according to customer customized specifications. The 3-speed adjustable saw blade speed adapts to sawing of different metal materials, with high cutting efficiency and smooth cutting surface, reducing subsequent processing procedures.

  • Machinery Spare Part & Repair Factories

    Used for cutting repair blanks and spare part raw materials of large industrial equipment such as reducers, machine tool spindles, hydraulic press columns and generator bases. The hydraulic automatic feeding shortens manual operation time, improving the efficiency of on-site maintenance and blanking of non-standard parts.

  • Auto & Heavy Equipment Supporting Production

    Performs blanking processing for large-diameter shaft blanks, flange rough castings and connecting rod raw materials in the production of heavy-duty auto parts, construction machinery accessories and hydraulic cylinder components. The high sawing precision ensures the dimensional accuracy of blanks, reducing material waste and processing costs of subsequent procedures.
