Key Product Features
1. High-Precision Servo & Ball Screw Shuttle Feed
Unlike traditional hydraulic-only feed carriages, the H-4050 features a high-performance AC servo motor combined with a precision ball screw drive. This arrangement provides lightning-fast indexing cycles and holds a repeat length positioning accuracy of ±0.1 mm, drastically reducing material trim waste.
2. Dual-Column Portal Structure with Hardened Guides
Built with a rigid double-column portal design featuring large, induction-hardened and chrome-plated guide columns. This gantry framework provides absolute rigidity and absorbs sawing harmonics, resulting in a flat, burr-free cut face and prolonged saw blade lifecycle.
3. Powerful 5.5 kW Drive & Helical Gearbox
Equipped with a heavy-duty 5.5 kW main motor paired with a high-efficiency helical gear reducer. This power transmission system delivers high torque at low blade velocities, preventing blade stalling when cutting dense structural steel shapes or solid alloy shafts.
4. Color Touchscreen PLC HMI
The intuitive HMI controller allows the operator to program and store up to 100 distinct cutting schedules (lengths and counts). The system monitors blade speed, feeds, and runs diagnostic checks automatically, supporting fully unattended operation.
5. Full-Stroke Double Hydraulic Clamping Vises
Workpieces are clamped on both sides of the blade's path by dual full-stroke hydraulic split vises. Double clamping eliminates material twisting and workpiece vibration, promoting straight cuts and preventing blade tooth damage.
6. Hydraulic Blade Tensioning & Powered Wire Brush
An automated hydraulic cylinder maintains the tension of the 41mm blade at the optimal level, compensating for thermal expansion. A powered steel wire brush continuously cleans metal chips from blade gullets to maintain cutting efficiency.
Industrial Applications
The H-4050 is designed for high-capacity, heavy-duty cutting operations:
Metal Service Centers & Steel Stockholders
Perfect for rapid volume sawing of large-diameter solid bars, heavy structural H-beams, structural channels, and thick-walled steel pipes.
Heavy Machinery & Shipbuilding
Allows continuous processing of large forged shafts, thick steel plates, casting sprues, and high-tensile structural profiles with precise dimensions.
Forge & Tool Steel Shops
Acts as the robust primary sawing stage, preparing high-weight block stocks and tool steel blanks for forging presses and large CNC mills.
Frequently Asked Questions
1. Why is a servo-driven shuttle feed superior to a hydraulic one?
Servo motor and ball screw systems provide precise speed control, fast acceleration, and deceleration. They do not suffer from hydraulic oil temperature variations, which can cause feed carriage drift. This ensures a consistent repeat feed accuracy of ±0.1 mm, saving time and money on secondary facing operations.
2. What are the advantages of the 41 mm wide blade on the H-4050?
A 41 mm wide blade is 30% wider than standard 34 mm blades, which gives it much greater beam strength. This allows for higher feed pressures and faster downfeeds without blade deflection, ensuring straight cuts on large cross-sections of tough metals.
3. Can the H-4050 handle bundle or pack cutting?
Yes. The machine can be customized with optional hydraulic overhead nesting clamps. This allows the operator to bundle round bars or rectangular tubes vertically and horizontally, securing the entire pack for high-speed multi-cut batching.
4. What shipping support and warranty are included?
The H-4050 is covered by a 1-year comprehensive B2B warranty. We provide export seaworthy packaging, shipping coordinates from our main port, operational training manuals, and remote video technical installation support.
