The Karmetal KSA 350×450 is a semi-automatic pivot-type bandsaw engineered for high-precision straight cutting of structural solids and profiles. Featuring a robust cast-iron saw frame, it provides the structural stability required for consistent industrial output. While material feeding is performed manually, the automated cutting cycle—including the downward descent and upward return of the saw bow—is fully managed by a hydraulic system. Powered by a high-torque 5.36 hp (4 kW) main motor, this machine represents a reliable solution for medium-to-large scale industrial workshops.

General

PRECISION POWER & HYDRAULIC CONTROL

The KSA 350x450 integrates a high-efficiency drive train with sensitive hydraulic regulation to optimize the processing of structural steel.

  • High-Efficiency Drive Train: Features a 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 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 .
