The Karmetal KSA 300×400 is a semi-automatic pivot-type bandsaw specifically engineered for high-precision straight cutting of structural steel and solid sections. It utilizes a robust cast-iron saw bow with a hydraulic suspension cylinder to manage automated descent and return cycles. Powered by a 2.95 hp (2.2 kW) main motor, this machine offers a compact yet heavy-duty industrial solution for consistent material processing in professional workshops.

General

HYDRAULIC EFFICIENCY & RIGID DRIVE

  • High-Efficiency Drive Train: Features a PKD 1390 bevel helical gearbox that provides superior torque transmission for stable cutting in dense structural solids.
  • Variable Speed Control: An integrated inverter allows the blade speed to be adjusted between 82 – 295 ft/min (25 – 90 m/min) to suit varying material hardness.
  • Hydramechanical Tensioning: Includes a specialized hydramechanical blade tensioning system to maintain blade rigidity and prevent curved cuts in heavy structural steel.
  • Precision Guidance: Employs a bedding system with carbide plates and bearings to ensure accurate blade alignment and extended tool life.

Features

  • Full-Stroke Clamping: A full-stroke hydraulic vise provides secure workholding across the entire material range, managed directly from the manual control panel.
  • Pressure Regulation: Includes adjustable vise pressure and an integrated manometer to safely secure thin-walled structural steel without deformation.
  • Integrated Cooling: Features a high-efficiency S.A.P. (Italy) brand coolant pump to manage thermal loads during continuous production cycles.
  • Managed Chip Removal: A motorized swarf brush keeps the wheels and blade clean to extend tool life and improve cut quality.
  • Industrial Safety Suite: Standard safety sensors for the covers, blade tension, and electric cabinet trigger an automatic stop if safety conditions are breached.
