Key Product Features
1. Vertical Hydraulic Nesting Clamps
Equipped with heavy-duty vertical nesting fixtures that apply downward hydraulic pressure on bundle arrays. This vertical clamping prevents the individual tubes or bars in the center of the pack from rotating or sliding during cuts, eliminating blade stripping.
2. Multi-Stroke NC Shuttle Feed Vise
Features an automated NC shuttle feeding vise mounted on precision guide rails. For cuts longer than the single 500mm carriage stroke, the PLC controller executes automatic multi-index feed cycles to reach any pre-programmed length.
3. Programmable PLC & Touchscreen HMI
An intuitive touchscreen PLC panel allows operators to store job programs with multiple cut lengths and batch quantities. The machine cycles automatically through the programs, stopping automatically when the batch is finished.
4. VFD Variable Blade Speed Regulation
The Variable Frequency Drive allows stepless adjustment of blade speed from 20 to 80 m/min via the control panel. This enables instant matching of the blade speed to the specific material hardness, optimizing tooth life.
5. Double-Column Gantry Framework
Designed with a dual-column gantry support frame that balances cutting forces evenly. This prevents frame twist and absorbs cutting vibrations, promoting clean, square, and burr-free cuts.
6. High-Flow Dual-Nozzle Flood Cooling
Delivers ample coolant fluid directly to both the entry and exit carbide guide blocks. This dissipates friction heat, flushes chips away from the teeth, and prevents work hardening on material cut faces.
Industrial Applications
The H-3542S is the preferred bundle-cutting solution for high-throughput fabrication sectors:
Construction Rebar Fabrication
Perfect for processing large bundles of steel reinforcement bars (rebars) for construction concrete, cutting dozens of bars simultaneously.
Steel Pipe & Conduit Distributors
Enables fast, square batch sawing of steel electrical conduits, black pipes, galvanized tubing, and rectangular profiles.
Structural & Fencing Manufacturers
Saves time and labor by cutting structural square tubing, channels, and angles in nested bundle arrays under automatic cycle schedules.
Frequently Asked Questions
1. Why are vertical nesting clamps necessary for bundle cutting?
If you only clamp a pack of round bars or tubes horizontally, the material in the center can rotate or shift because horizontal force doesn't distribute evenly. Dynamic vertical top-clamps secure the bundle from the top, ensuring every single piece behaves as a solid block. This is critical to prevent blade tooth breakage.
2. How many rebars can the H-3542S cut in a single cycle?
The capacity depends on the rebar diameter. With a nesting width of 420mm and height of 350mm, it can clamp up to 50 pieces of 20mm rebar or over 100 pieces of 12mm rebar in a nested pack.
3. What is the difference between H-3542S and H2-6580S?
The H-3542S is specifically equipped with nesting fixtures for bundle cutting of structural profiles and medium bars up to 350x420mm. The H2-6580S is a much heavier gear-reducer model (3,200 kg vs 1,800 kg) designed primarily for slicing large solid tool steel blocks up to 650x800mm.
4. What are the standard lead times and warranty?
Standard H-3542S models have a lead time of 30 to 45 days. The machine is backed by a 1-year comprehensive industrial warranty. We supply seaworthy packaging, detailed operating manuals, electrical diagrams, and remote video commissioning support.
