The Karmetal WOS 500×550 is a PLC-controlled automatic double column bandsaw designed for high-precision straight cutting of medium-to-large solids and material bundles. Featuring a robust dual-column frame and a precision linear guide system, the machine ensures maximum structural stability and squareness accuracy. Equipped with standard dual hydraulic top clamps, it is an ideal industrial solution for mass-producing stacks and packages with high repeatability. Controlled via an 8.4” HMI touch screen, the WOS 500×550 utilizes a servo-driven feeding system to automate production workflows and optimize cycle times.

General

PRECISION BUNDLE AUTOMATION

The WOS 500x550 combines mechanical rigidity with advanced PLC programming for high-volume output.

  • 8.4” HMI Touch Control: A user-friendly interface supporting 11 languages. It allows operators to program up to 20 different cutting dimensions and store 50 unique job lists, facilitating rapid setup for recurring production batches.
  • Dual Hydraulic Top Clamping: Specifically engineered for bundle cutting, these standard vertical clamps secure multiple workpieces from above, preventing material rotation and vibration for a cleaner cut and longer blade life.
  • Servo-Driven Feeding System: High-torque servo motors paired with a PLC system manage material indexing with sub-millimeter accuracy, automatically handling multi-stroke feeding for workpieces longer than the single stroke limit.
  • Linear Guide Architecture: The saw bow travels vertically on precision-ground linear guides. This reduces friction and eliminates the "play" found in traditional slide systems, providing a perfectly smooth descent during heavy-duty cutting.
  • Bevel Helical Gearbox: Equipped with a high-efficiency drive system that ensures maximum torque transmission from the 7.3 HP (5.5 kW) motor, maintaining consistent blade speeds even under high loads.

Features

  • Double Vise System: Features both front and rear hydraulic vises to maintain absolute control of the material on both sides of the blade throughout the entire cutting process.
  • Adjustable Vise Pressure: Hydraulic clamping pressure can be independently regulated to protect thin-walled profiles or delicate materials from deformation.
  • Integrated Chip Management: A standard pallet-type automatic chip conveyor and a motorized blade cleaning brush ensure continuous operation by effectively removing hot metal debris.
  • Comprehensive Safety Suite: The machine includes an automatic stop system triggered by blade breakage, pressure drops, blade jamming, or the opening of safety covers.
  • Variable Blade Speed: Managed via an inverter, allowing the operator to adjust the speed between 72–328 ft/min to suit different steel grades and alloys.
