The Universal Press 3100 x 13 Mod. CS 20 hydraulic shear with a 550 mm throat is an extremely robust and versatile used machine, perfect for companies that work with large sheet metal. Manufactured by the renowned Universal Press, it is a model widely recognized in the machine tool industry for its reliability and cutting capacity. This specific model can cut sheet metal with a maximum thickness of 13 mm and a length of 3100 mm , making it ideal for demanding industrial applications.

The Universal Press CS 20 hydraulic shear features a solid steel body, designed to withstand prolonged use. Visually, it is a stable and well-balanced machine, with a robust design that inspires safety and reliability. The 550 mm provides ample sheet metal handling, especially for deep and precise cuts.

The machine's motorized register allows you to precisely set the desired cutting position, minimizing errors and optimizing production times. This component is essential for those who require precision during series production.

The technical specifications of the Universal Press 3100 x 13 Mod. CS 20 include a highly efficient hydraulic system, powered by a three-phase motor that provides the power needed to handle large sheet thicknesses. Some of the most important technical data include:

• Cutting length: 3100 mm
• Maximum cutting thickness: 13 mm
• Recess: 550 mm
• Motor power: typically between 15 and 22 kW (depending on configurations)
• Adjustable cutting angle to improve efficiency on different materials
• Rapid cycle capability thanks to advanced hydraulic control system

The machine is equipped with mechanical and electronic protections to ensure operator safety during operation, as required by current regulations. Although CE compliance is not always specified for used machines, it can be upgraded with the addition of updated safety devices, such as light curtains or automatic safety interlocks.

The Universal Press Mod. CS 20 shear is easy to use thanks to its intuitive control panel, which allows the operator to adjust all cutting parameters with extreme precision. After positioning the sheet metal on the workbench, the operator sets the motorized fence and adjusts the cutting angle based on the material being processed. The hydraulic system then performs the cut with quick and decisive movements, ensuring smooth, clean edges.

These shears are widely used in metal fabrication, construction component manufacturing, and sheet metal fabrication for the automotive and aerospace industries. Their ability to cut sheet metal up to 13 mm makes them perfect for heavy-duty, prolonged operations without sacrificing precision.

Optional accessories may include:

• Rear sheet metal supports , to facilitate the handling of large pieces
• Automatic loading tables , to increase productivity
• Cutting area lighting systems , useful for improving visibility during precision machining

To calculate the optimal operating parameters, it is essential to consider the type of material being worked. For example, for mild steel with a thickness of 13 mm , the force required for cutting can be approximately calculated using the formula:

$$F$$

Where:

• F is the force required (in Newtons),
• S is the thickness of the sheet metal (in mm),
• L is the cutting length (in mm),
• k is a coefficient that varies according to the material (for steel it is generally between 0.6 and 0.8).

Maintenance of the Universal Press Mod. CS 20 is relatively simple, but essential to keep the machine in perfect operating condition. It's necessary to regularly check the hydraulic oil level, lubricate moving components, and replace the blades when signs of wear appear. Hydraulic system seals should be replaced periodically to prevent leaks and ensure continued, safe operation.

Furthermore, to ensure operator safety, it is essential that the machine is equipped with adequate protections and used in compliance with current regulations. If the machine is not CE , it is recommended to upgrade it by installing additional safety devices.

Buying a used Universal Press 3100 x 13 Mod. CS 20 hydraulic shear can be a very advantageous deal. This machine, even used, is synonymous with reliability and durability. A careful inspection of the condition of the hydraulic motor, blades, and structural components is essential to determine whether it's a good deal.

Compared to purchasing a new machine, a used one offers significant cost savings while still retaining many of the original features. The build quality of the Universal Press Mod. CS 20 ensures that, with proper maintenance, this shear will last for many years to come, offering excellent production output at a reasonable cost.
