ndustrial Power: The Automatic Rising Blade Saw Ø 700 mm
In the world of heavy-duty industrial fabrication, the Automatic Rising Blade Saw Ø 700 mm (also known as an Upcut Saw) represents the pinnacle of single-head cutting technology. Designed for high-volume production environments, this machine is specifically engineered to handle extra-large aluminum extrusions, thick-walled PVC, and non-ferrous metal profiles that standard saws simply cannot accommodate.
The Rising Blade Mechanism: Why It Matters
Unlike traditional “drop saws” where the blade moves downward, the rising blade mechanism operates by pushing the saw upward from beneath the worktable. This design offers several critical engineering advantages:
Superior Stability: As the blade rises, the cutting force naturally pushes the profile down against the solid machine bed. This significantly reduces vibration and prevents the material from “lifting” or shifting, resulting in a cleaner, more accurate cut.
Safety by Design: When not in use, the Ø 700 mm blade is completely retracted beneath the table. Modern models feature a pneumatically operated safety guard that fully encloses the cutting area before the blade emerges.
Variable Feed Control: These machines typically utilize hydro-pneumatic feed systems. This allows the operator to infinitely adjust the rising speed, ensuring a perfect finish whether cutting thin-walled PVC or solid aluminum bars.
Key Technical Specifications
A 700 mm blade diameter (approximately 28 inches) places this machine in the heavy-duty class. Standard specifications for 2026 models usually include
Blade Diameter: Ø 700 mm (TCT – Tungsten Carbide Tipped for longevity).
Motor Power: High-torque motors ranging from 4.0 kW to 5.5 kW (5.5 to 7.5 HP).
Cutting Range: A massive pivoting range, typically from $-75^\circ$ to $+75^\circ$, with fixed detents at common angles ($15^\circ, 22.5^\circ, 30^\circ, 45^\circ, 60^\circ, 75^\circ$).
RPM: Optimized at approximately 2,000 RPM to balance cutting speed with heat management.
Clamping: Dual horizontal and vertical pneumatic clamps ensure the profile remains immobile during the high-energy cutting cycle.
Advanced Features for 2026
Modern iterations of the Automatic Rising Blade Saw are no longer just mechanical tools; they are data-driven workstations:
LED Interior Lighting: For clear visibility of the cutting line and material positioning.
Spray Mist Lubrication: An automated system that applies a fine cooling mist to the blade, essential for preventing “chip welding” when processing aluminum.
Laser Line Indicators: Projects a precise laser line onto the profile to show exactly where the blade will emerge, reducing measurement errors.
Digital Angle Display: High-resolution screens that show the exact pivoting angle to a tenth of a degree, replacing old manual scales.
Applications: Built for the Big Jobs
The Ø 700 mm capacity makes this saw the preferred choice for specific, demanding industries:
Architectural Facades: Cutting the massive mullions and transoms used in skyscraper glass walls.
Industrial Extrusions: Processing heavy aluminum parts for the automotive and rail industries.
Structural PVC: Handling thick, multi-chambered vinyl profiles for high-performance window systems.
Bundle Cutting: The large surface area allows for cutting multiple smaller profiles simultaneously, significantly boosting output.
Conclusion
The Automatic Rising Blade Saw Ø 700 mm is the “heavy lifter” of the fabrication floor. It combines the brute force of a 7.5 HP motor with the finesse of hydro-pneumatic control. For manufacturers who have outgrown standard 450 mm or 500 mm saws, this machine provides the necessary capacity to take on larger, more complex industrial projects while maintaining a safe and efficient workspace.
