Condition: new, Year of construction: 2026, For sawing, e.g., stainless steel, tool steel, hollow profiles, and solid materials. Two-pole drive motor enables saw blade speeds of 30 and 65 m/min. Monitoring of the saw blade tension electromechanically via microswitches. When the saw arm is raised, the lowering cylinder locks in the upper position via the solenoid valve – additional locking on the cylinder is therefore not required. Saw arm inclined by 25°, resulting in a longer service life of the saw blade. Precise and robust blade guides with adjustable carbide plates. After the cutting process is completed, the saw blade stops automatically in the lower end position. Lowering of the saw arm by gravity or manually. With continuously adjustable, constant saw arm lowering speed via hydraulic cylinder.
