The CBC model T50/20 IS press brake is a robust and versatile industrial machine, ideal for those looking for a reliable used machine for precise machining. Designed for bending and shearing sheet metal, this press brake is equipped with an advanced Cybelec Multiprocessor 73 , which allows for precise control of operations and a user-friendly interface.

Components and dimensions

The CBC T50/20 IS has a solid structure with a total weight of 4,100 kg . The maximum bending length is 2,150 mm , with an upper beam stroke of 110 mm and a distance between the frames of 1,630 mm . The maximum clearance between the table and the beam reaches 300 mm 250 mm throat provides greater flexibility for inserting bulkier workpieces.

Mechanical characteristics

This model operates with a press force of 50 tons , sufficient to bend a wide range of sheet metal thicknesses. The back gauge has a 500 mm and can be automatically adjusted on the Z1, Z2 and X1 axes, with the possibility of future additions to increase precision. The CBC T50/20 IS is also equipped with a CNC-controlled automatic crowning system, which helps maintain precision even on long bends.

Use and operating procedures

To use the machine correctly, you begin by configuring the Cybelec CNC, entering the bending parameters such as angle, descent speed, and ascent speed. The system supports variable working speeds: 4,000 mm/s descent , 1,000 mm/s actual work, and 5,000 mm/s ascent. Once the tools are set, the material can be positioned on the worktable, and the bending process occurs with automatic precision thanks to the CNC. CNC-controlled bending machines are particularly suitable for series production, where precision and repeatability are essential.

Matching accessories

Accessories that can be combined with the CBC T50/20 IS include various bending tools, interchangeable dies, and automatic back-adjustment systems, useful for improving efficiency and adapting to different types of machining. It is compatible with Promecam attachments and manual dies, expanding its versatility.

Mathematical formulas for optimal parameters

To calculate the forces required for optimal bending, the formula can be used:

$F$

Where:

• FF $F$ is the force in tons,
• LL $L$ the bending length in mm,
• TT $T$ the thickness of the sheet metal in mm,
• VV $V$ the width of the matrix in mm.

This formula helps avoid overloads and ensure that the machine operates within safe limits.

Workable materials and sectors of use

The CBC T50/20 IS can process various types of sheet metal, such as mild steel, stainless steel, and aluminum. It is widely used in the metalworking, construction, and automotive industries, thanks to its ability to handle precision bending on metal components.

Maintenance and evaluation of used vehicles

Careful maintenance is essential to maintain the high performance of this press. Regular checks of the hydraulic oil, seals, and CNC system are recommended. When evaluating a used machine, it's important to check the structural integrity, the absence of leaks in the hydraulic system, and the functionality of the CNC control. The CBC T50/20 IS is an excellent choice for those seeking high-performance machinery at a lower price than new, offering high precision and reliability at a reasonable cost.
