Key Product Features
1. Robust Portal Double-Column Structure
The main frame utilizes an oversized double-column portal design supported by chrome-plated columns and hardened guides. This massive gantry structure neutralizes heavy-duty cutting forces and dampens blade resonance, ensuring excellent flatness and perpendicularity on large steel sections.
2. Powerful 7.5 kW Main Drive & VFD Speed Control
Powered by a robust 7.5 kW main motor integrated with a variable frequency drive. It delivers high cutting torque across the entire VFD range of 15 to 90 m/min, allowing operators to match speed to high-hardness tool steels or mild alloys without motor lugging.
3. Advanced PLC HMI Touchscreen System
Features an intuitive PLC control unit where operators can easily program cutting lengths and batch sizes. Material feed positioning is monitored by a rotary encoder, guaranteeing repeatable cuts and reducing operator workload.
4. Automatic Hydraulic Dynamic Blade Tensioning
Continuously adjusts blade tension hydraulically. The system automatically compensates for thermal expansion of the 54 mm blade during long portal cuts, maintaining cut straightness and preventing premature blade fatigue.
5. Dual Full-Stroke Hydraulic Clamping Vises
Equipped with front and rear split hydraulic vises that clamp workpieces firmly on both sides of the kerf. The dual clamp setup holds heavy bars and structural profiles securely, preventing material movement and blade binding.
6. High-Flow Coolant & Chip Flushing
A high-capacity flood coolant pump delivers fluid directly to guide arms and workpiece. Combined with a powered chip brush, it flushes chips away from the cut zone to maintain surface quality and reduce blade wear.
Industrial Applications
The H2-80100S is engineered for high-throughput, heavy-capacity industrial operations:
Steel Supply & Service Centers
Efficiently slices large steel plates, heavy-walled columns, massive structural H-beams, and bundle tubes to custom commercial lengths.
Heavy Forging & Casting Foundries
Capable of cutting massive cast ingots, forged steel shafts, and large machinery parts before or after heat treatment operations.
Shipbuilding & Heavy Steel Fabrication
Enables large-capacity, long-stroke cutting of structural sections, gantry components, and heavy plates with clean, weld-ready cut faces.
Frequently Asked Questions
1. What are the benefits of the 54 mm blade on the H2-80100S?
A 54 mm wide blade has significantly higher torsional rigidity and beam strength than standard 34 mm blades. This allows the machine to handle heavy feed pressures on wide sections up to 1000mm without bowing, ensuring straight cuts on large steel blocks and plates.
2. How accurate is the encoder feed positioning system?
The NC controller utilizes precision rotary encoders coupled with the hydraulic shuttle feed carriage. This delivers repeatable indexing feed accuracy, making it ideal for preparing blank blocks for large CNC milling centers with minimal machining allowance.
3. Does it support bundle or bundle-stack cutting?
Yes. For structural steel fabrications or profile bundles, the H2-80100S can be equipped with custom vertical hydraulic nesting clamps to secure stack packs tightly for batch cutting.
4. What shipping, packaging, and commissioning support do you offer?
Due to the heavy machine weight (4,850 kg), the saw is shipped as a split unit in seaworthy export packaging. We provide shipping coordination, complete operational documentation, wiring diagrams, and remote or on-site installation support.
