Chamunda Hydraulic C Frame press machine
C-frame hydraulic presses, also known as gap-frame presses, are primarily defined by their three-sided access and compact vertical design. While individual models vary, the following are the standard technical specifications and features for these machines: 1. Key Technical ParametersThese metrics determine the machine's capacity and operational speed: 

• Pressing Capacity (Tonnage): Ranges typically from 5 tons to 300 tons for standard models, though heavy-duty units can reach 500+ tons.
• Stroke Length: Typically between 100 mm and 500 mm, representing the distance the ram travels.
• Daylight (Open Height): The distance between the bed and the ram in its highest position, commonly 300 mm to 1400 mm.
• Throat Depth: The horizontal distance from the centre of the ram to the frame, usually 150 mm to 350 mm.
• Travel Speeds:
  • Fast Approach: 40–225 mm/sec (rapid descent to the workpiece).
  • Pressing Speed: 1–15 mm/sec (slow force application).
  • Return Speed: 10–180 mm/sec (rapid retraction).
• Table/Bed Size: Varies by capacity, common sizes include 400 x 350 mm for 20-ton units up to 900 x 600 mm for 200-ton units. 

2. Physical & Material Specifications

• Frame Construction: High-grade fabricated mild steel (IS-2062) or cast iron for maximum rigidity and minimal deflection under load.
• Cylinder & Ram: Hard chrome-plated piston rods (typically 0.200 micron plating) and honed cylinders for long seal life.
• Motor Power: Standard electric motors ranging from 2 HP to 25 HP depending on tonnage.
• Weight: Approximately 1,000 kg for 10–20 ton models, scaling up to 13,500 kg for 75-ton industrial units. 

3. Standard Features & Controls

• Operation Modes: Manual, Semi-Automatic, or Fully Automatic (often PLC or CNC controlled).
• Safety Mechanisms: Emergency stops, two-hand push-button starts, and safety light curtains (SICK or similar) to protect the operator.
• Control Panel: HMI touch screens for parameter setting (tonnage, stroke, speeds) and cycle counting.
• Hydraulic System: Compact manifolds to reduce piping and noise, with built-in pressure relief valves for overload protection.

chamunda c type hydraulic press machine
A C-type hydraulic press machine, often called a C-frame or gap-frame press, is an industrial tool shaped like the letter "C" to provide three-sided access to the workspace. It uses hydraulic fluid to generate consistent, high-pressure force for tasks like metal forming, punching, and assembly. Its compact, open-front design makes it a standard choice for both small workshops and large-scale manufacturing lines. Key Features and Specifications

• Three-Sided Access: The open "C" structure allows operators to load and unload materials from the front and both sides, facilitating the handling of wide or irregularly shaped workpieces.
• Variable Tonnage: Machines typically range from light-duty 5-ton models to heavy-duty industrial versions exceeding 500 tons.
• Precision Control: Advanced models often feature PLC (Programmable Logic Controller) systems and HMI touchscreens, allowing for precise adjustment of stroke length, pressure, and speed.
• Compact Footprint: These presses occupy significantly less floor space than H-frame or four-column presses, making them ideal for space-constrained environments.
• Safety Systems: Standard safety equipment includes emergency stop buttons, two-hand operation controls, and infrared safety light curtains to protect the operator during the pressing cycle. 

Common Industrial Applications

• Metalworking: Sheet metal bending, punching, blanking, embossing, and trimming.
• Automotive: Assembling components like gears, brackets, and housings, or straightening shafts and pressing bearings.
• Electronics: Precision pressing for connectors, terminals, and motor rotor/stator assemblies.
• General Assem

Chamunda C Frame Press Technical Parameters Key Features & Components

• Frame Construction: Typically fabricated from high-grade rolled steel plates (e.g., IS-2062) for rigidity and minimal deflection under full load.
• Hydraulic System: Includes a compact power pack, double-acting cylinders with hard chrome-plated piston rods, and pressure relief valves for overload protection.
• Control Modes: Most machines offer Manual, Semi-Automatic, and Fully Automatic modes via a PLC or HMI control panel.
• Safety Features: Standard inclusions often comprise safety light curtains, two-hand push-button controls, and emergency stop buttons.
