Key Product Features
1. High-Torque Helical Gearbox Transmission
The motor drives the main band wheel through a direct-coupled helical gear reducer. This industrial transmission delivers high torque at lower speeds, preventing drive belt slippage and ensuring smooth cutting on dense alloys and solid steel shapes.
2. Semi-Automatic Hydraulic Cutting Cycle
A single button push executes the entire cutting sequence: hydraulic vise clamping, VFD-regulated motor start, downfeed cylinder control, automatic motor shut-off upon cut completion, and automatic frame elevation back to home position.
3. Reinforced Dual-Column Gantry Portal
Engineered with a heavy portal frame and oversized vertical columns. This reinforced gantry layout absorbs cutting harmonics, prevents blade twisting, and maintains perfect cut squareness on heavy profiles and solid bars.
4. Heavy-Duty 41 mm Wide Saw Blade
Uses a wider 41 mm bimetal blade which offers 30% more beam strength than standard 34 mm blades. This additional rigidity allows for higher downfeed pressures and faster cutting speeds without sacrificing straightness.
5. Premium Dual Carbide Blade Guides
Guided by adjustable carbide blocks and pre-alignment ball bearings. This dual guide arm system stabilizes the blade close to the cut point, maximizing cutting precision and reducing thermal friction.
6. Dynamic Flood Coolant & Powered Chip Brush
A high-flow pump flood recirculates coolant to lubricate the cut zone. Paired with a powered wire wheel brush, it clears metal shavings from blade gullets to maintain tooth penetration and protect the blade.
Industrial Applications
The UP-43S is designed for high-efficiency primary metal sawing in large workshops:
Steel Stockholders & Distribution Yards
Enables semi-automatic cutting of large carbon steel bar stocks, heavy structural channels, square profiles, and thick-walled pipes to size.
Heavy Machinery & Tooling Shops
Handles blank preparation of tool steel blocks, solid alloy steel shafts, and forge blanks under multi-shift operation.
Structural Fabrication Plants
Processes massive structural H-beams, structural steel tubes, and angle frames with precise cut faces ready for welding.
Frequently Asked Questions
1. What makes the UP-43S different from the UP-33N?
The UP-43S is a larger and more heavily reinforced machine. It expands cutting capacity from 330mm to 400mm, uses a wider 41mm blade (instead of 34mm) for higher beam strength, features a direct helical gear drive (instead of VFD belt drive), and weighs 2,200kg (vs 1,650kg) for superior vibration dampening.
2. Why is the direct gear reducer drive important for solids?
Solid steel bars present constant resistance. Standard belt-driven saws can experience slippage, leading to blade deceleration and tooth glazing. The UP-43S's direct-coupled gearbox delivers consistent mechanical torque, ensuring a stable cut velocity.
3. Does it support bundle clamping?
Yes. We offer optional hydraulic vertical nesting clamps that can be integrated with the main clamping vise, allowing vertical bundle cutting of tubes or small round bars.
4. What shipping, packaging, and warranty are standard?
We ship the UP-43S in seaworthy export-compliant packaging. It is backed by a 1-year B2B industrial warranty. We provide comprehensive operational drawings, wiring manuals, and remote video technical installation support.
