Condition: new, Year of construction: 2026, CORMAK G5025 Metal Band Saw The CORMAK G5025 metal band saw is a professional band sawing machine designed for precise cutting of pipes, profiles, bars, and components made from various grades of steel. Its robust construction, hydraulic control of arm descent, and two blade speeds make the machine suitable for both one-off and batch production. Key Advantages of the CORMAK G5025 Band Saw Two blade speeds – 36 and 72 m/min – allow the operating parameters to be adjusted to the type of material being processed. Hydraulic, stepless control of arm descent – enables precise control of the feed rate during cutting. Robust arm made of profiled cast iron – provides high structural rigidity and reduces vibration. Bearing and carbide blade guides – ensure stable and precise guidance of the cutting blade. Arm swivelling in both directions – allows angled cuts in the range from -45° to +60°. Cooling system – an electric pump and drain tray help effectively remove heat and contaminants from the cutting area. Automatic drive shut-off after completion of the cut – increases safety and ease of use. Guards and safety microswitches – provide increased operator protection during operation. Rigid Cast-Iron Arm The saw arm is made of profiled cast iron. The high rigidity of the construction reduces vibrations generated during machining and helps maintain accurate cutting geometry. Cutting Blade Drive The drive is transmitted from the electric motor through a worm gearbox to the drive wheel that powers the cutting blade. This solution ensures stable operation of the system and appropriate torque transmission when cutting steel components. Precise Blade Guiding and Tensioning The blade is guided by adjustable bearing and carbide guides. The mechanical manual tensioning system allows the blade to be properly prepared for operation and maintains the correct blade tension. Hydraulic Arm Descent Control The stepless hydraulic adjustment allows the arm descent speed to be precisely adapted to the type, shape, and cross-section of the material being cut. This provides smoother cutting and helps reduce excessive load on the blade. Arm Adjustment Range from -45° to +60° The arm's ability to swivel in both directions increases the versatility of the band saw. The design allows both standard straight cuts and angled cuts in the range from -45° to +60°. Standard Equipment main motor with worm gearbox, adjustable blade guides, cooling system with electric pump, stable welded base, control panel mounted on the arm. Optional Equipment roller table extension.
