Technical SpecificationsWhile specific features vary by manufacturer (such as chamunda engg works, standard 80T/2500 models typically share these parameters: 

• Bending Force: 800 KN (80 Tons).
• Bending Length: 2500 mm (2.5 Metres).
• Distance Between Columns: Approximately 2050 mm to 2100 mm.
• Throat Depth: 250 mm to 320 mm.
• Stroke Length: 100 mm to 120 mm.
• Main Motor Power: 5.5 KW (approx. 7.5 HP).
• Speed: Fast approach at ~45–50 mm/s; bending at ~5–8 mm/s; return at ~45–60 mm/s. 

Key Features & Components

• Control Systems: manual limit switch setting on bending stroke and manual handle operate back gauge stopper.
• Synchronization: Most use a torsion bar system to maintain parallelism between the two hydraulic cylinders, ensuring consistent bends across the length of the sheet.
• Backgauge: Motorized backgauges with ball screws are common for high-precision positioning (often ±0.1mm accuracy).
• Structure: Heavy-duty welded steel frames, often stress-relieved for high rigidity and stability during high-pressure operations.

Frame Construction: Usually a monoblock welded steel frame (often using IS 2062 grade steel) for maximum rigidity and minimal deflection under load. Control System: Manual/NC: Uses basic digital readouts for stroke and backgauge positioning. CNC: Employs advanced controllers (e.g., Delem, Cybelec) to automate multiple axes (Y1, Y2, X, R, Z1, Z2) and complex bending sequences. Backgauge: Motorized or servo-driven systems that position the metal sheet with high precision (repeatability up to ± 0.1 mm). Power Requirements: Typically runs on 3-phase power (220V/440V) with motor sizes ranging from 3 HP to 50+ HP depending on tonnage. Energy Mission Energy Mission +7 Standard & Optional Accessories Tooling: Standard sets usually include a multi-V die (bottom) and a gooseneck or standard punch (top) made of hardened alloy steel like EN-8 or EN-31. Safety Features: Includes emergency stops, foot pedal controls, and often optional laser guards or light curtains to protect operators. Crowning System: An auto-compensation mechanism (manual or hydraulic) that prevents the "bowing" effect in the center of long bends, ensuring a consistent angle across the entire length.

Tonnage: Typically ranges from 30 MT to 500+ MT (Metric Tons), determining the thickness and length of material that can be bent. Bending Length: Common sizes include 1500mm, 2500mm, 3200mm, and 4000mm. CNC Control Axes: Standard models often feature 3+1 (Y1, Y2, X + crowning) or 4+1 (Y1, Y2, X, R + crowning) axes, with high-end models having 6 or 8+ axes. Backgauge Range & Speed: X-axis range is typically 500-1000mm, with high-speed servo motors for rapid positioning. Daylight/Open Height: The maximum distance between the table and ram, often 350-500mm. Throat Depth: Typically 300-400mm, allowing for deeper, non-linear bends. Approach/Working/Return Speed: E.g., Approach: 100-180 mm/s, Working: 10 mm/s, Return: 100-120 mm/s. IndiaMART IndiaMART +6 Common Features Control Unit: Delem (DA53T, DA58T, DA66T), Cybelec (CybTouch 8/12 PS), or ESA. Hydraulics & Motors: Bosch Rexroth hydraulic valves and Siemens motors are standard. Safety System: Laser safety guards (e.g., Tailift Group's laser safety device) or light curtains. Crowning: Automatic hydraulic or mechanical crowning for compensation.

Tonnage (Bending Force): Represents the maximum force the machine can exert. Standard industrial models typically range from 40 tons to 1,000+ tons. Higher tonnage is required for thicker or harder materials. Bending Length: The maximum length of the material the machine can bend at once, usually ranging from 1.2 to 6 metres (4 to 20 feet). Stroke Length: The vertical distance the ram (upper beam) travels. Common ranges are between 100 mm and 380 mm. Open Height (Daylight): The maximum distance between the bed and the ram when fully retracted, typically 250 mm to 600 mm, which determines the height of dies that can be used. Throat Depth: The distance from the center of the ram to the machine's back frame. A deeper throat (e.g., 200 mm to 500 mm) allows for bending larger or more complex "box" shapes. +6 Operational Speeds Modern machines utilize a three-stage speed system to optimize productivity: Approach Speed: High-speed descent towards the material (e.g., 50–180 mm/s). Working/Bending Speed: Controlled slow speed during the actual bend (e.g., 6–22 mm/s) to ensure accuracy. Return Speed: Fast ascent after the bend is completed (e.g., 40–200 mm/s)
