The Karmetal KSA 500×650 is a heavy-duty semi-automatic double column bandsaw specifically designed for high-precision straight cutting of heavy solids and structural steel. It features a rigid dual-column frame integrated with a linear guide system to ensure maximum stability and perpendicular accuracy for workpieces up to 19.68×25.59 in(500×650 mm). While material feeding is manual, the automated cutting cycle is managed via a digital control interface and powered by a high-torque 7.37 HP (5.5 kW) motor, making it a robust solution for demanding industrial production

General

INDUSTRIAL RIGIDITY & CONTROL

The KSA 500x650 combines a high-rigidity structural frame with precise hydraulic management for consistent performance.

  • Double Column Architecture: The saw frame travels vertically along two precision-ground columns using roller-type linear guides , which effectively dampens vibrations and prevents blade deflection.
  • Digital Control Interface: Operators manage the cutting process through a user-friendly digital control panel that provides real-time status monitoring and parameter adjustments.
  • Frequency Inverter Drive: The integrated inverter enables variable blade speed control between 82−295 ft/min(25−90 m/min) to optimize performance for various material grades.
  • High-Efficiency Gearbox: Equipped with a PKD 3390 bevel helical gearbox that ensures maximum torque transmission to the blade for stable cutting of dense structural steel.
  • Hydraulic Pressure Management: Features dedicated hydraulic regulation for both vise clamping and blade tensioning, allowing for secure material handling and optimized blade life.

Features

  • Adjustable Body Motion: The downward descent speed of the saw frame is fully adjustable and supported by a back pressure valve for fine-tuned penetration into high-resistance alloys.
  • Integrated Swarf Management: Includes an automatic pallet-type chip conveyor and a motorized swarf brush to maintain a clean workspace during continuous heavy-duty cycles.
  • Hydraulic Vise Clamping: Provides high-pressure secure clamping , with adjustable pressure settings monitored via a manometer to prevent deformation of structural profiles.
  • Precision Blade Guidance: Employs a blade yoking system with two bearings and carbide plates to maintain absolute squareness throughout the cut.
  • Industrial Safety Suite: Standard safety features include cover interlocks, blade tension sensors, and proximity switches that trigger an automatic stop in the event of faults.
