miterhorizontalfor metals

Overview
The automatic mitre band saw HBE420-723GA delivers high cutting performance, precision and easy operation. It cuts profile steel, tubes and solid steel or stainless steel at almost any angle. With a precise feed gripper and fast NC-controlled angle adjustment, the machine operates fully automatically.

Features

• Downfeed control with servo drive: ball-screw feed and servo motor for short non-productive times and precise feed movement
• Precision portal-design guide system: stable, low-vibration saw frame and linear guides for best cutting results and long service life
• Micro Spray System: standard minimal quantity lubrication with two nozzles to keep the blade moist for long blade life and a clean workplace
• 3° blade inclination: improved cutting performance on hollow profiles and beams with reduced burr formation
• Customer-oriented sawing concepts: system solutions prepared for individual material handling integration
• Safe material flow: closed table support and smart connection to handling systems to prevent jamming of short cuts and gussets
• Cast iron band guiding parts: vibration damping at the cutting edge to extend tool life
• Sensitive Behringer cutting pressure control: automatically adapts saw feed to changing cross-sections for higher cutting performance
• Automatic guide arm: consistent sawing results without manual adjustment, even with frequent size changes
• Hydraulic blade tensioning: optimal band tension, automatic stop on band breakage and band relief when machine stopped
• Electrically driven chip brush with quick‑change device for tool‑free brush replacement
• Energy-efficient drives: higher output with lower energy consumption
