The Karmetal KDG 460×800 DM is a heavy-duty double column semi-automatic bandsaw designed for high-precision straight and double miter cutting of structural solids and steel. This machine features a rotating table architecture that allows for precise miter cuts ranging from -45° to 60°. Utilizing a 7.37 hp (5.5 kW) main motor and roller-type linear guides, it handles structural steel workpieces up to 18.1 x 31.5 in (460 x 800 mm) with manual material feeding.
General
DOUBLE MITER PRECISION & STABILITY
- Double Column Architecture: Features a robust dual-column frame supported by linear guides to eliminate vibrations when processing heavy structural solids.
- Double Miter Capability: Integrated rotating table allows for miter positioning between -45° and 60° to suit complex fabrication requirements.
- Linear Guide Frame Motion: Employs roller-type linear guides for vertical frame movement to ensure long-term accuracy and smooth operation.
- Variable Frequency Drive: Includes a standard inverter to adjust blade speeds between 82 – 295 ft/min (25 – 90 m/min) based on material density.
- Hydraulic Pressure Management: Features sensitive cutting feed and pressure adjustment to optimize blade penetration through structural solids.
Features
- Miter Position Brake: Utilizes a hydraulic braking system to lock and unlock miter positioning via a button on the control panel.
- Hydraulic Top Clamping: Provides vertical hydraulic power designed for bundle cutting and stabilized workholding of structural steel.
- Triple Bearing Guidance: Guidance system utilizes carbide inserts and triple bearings on both sides to maintain blade perpendicularity.
- Motorized Swarf Removal: Equipped with an electrical motorized swarf brush and a spiral-type motorized swarf conveyor for automated debris management.
- Workplace Visibility: Includes a laser line indicator and LED workplace lighting for accurate setup on structural solids.
