Fasti 225 universal folding machine

Fasti 225 universal folding machine 

Working with the clamping beam:
The control system utilizes bilateral incremental position measurement from Heidenhain, ensuring continuous awareness of the clamping beam's precise position. Based on this data, the control system adjusts the proportional valves of the hydraulic unit, maintaining parallel accuracy for the clamping beam at all times, with deviations of less than 0.1 mm. This accuracy persists regardless of clamping pressure (up to 400 kN), variations in sheet thickness, or asymmetric loads. The hydraulic tool clamping system delivers unmatched force, while the 45° inclination of the clamping beam facilitates bending of U-shaped pieces with identical leg lengths using standard tools.

Guidance and lubrication:
Both the clamping and lower beam guides feature maintenance-free solid-lubricant slide bearings, resulting in a stick-slip behavior with minimal friction, perfectly suited to the machine's motion characteristics.

Working with the lower beam:
The box-type construction of the lower beam, with its delta-shaped cross-section, creates ample space behind the tool after the table elements have been moved, allowing for efficient folding operations.

Drive:
The robust hydraulic drive, constructed in a rugged design, boasts round cylinders equivalent to those used in crane construction, ensuring virtually zero leak rate over extended operation. The compact central manifold houses proportional valves, pressure valves, and safety elements, facilitating fast and reliable service work on the machine.

Working with the folding beam:
While crowning of the folding beam can be done manually, leaving this task to the control system (at a small additional cost) offers a simpler and safer alternative. Thanks to the special geometry of the folding beam, Z bends with leg lengths of over 30 mm can be achieved using standard tools.

Only a state-of-the-art machine will enable you to achieve the accuracy necessary for your work, a hallmark of FASTI.

Working with segmented tools offers numerous advantages, including cost-effectiveness and ergonomic efficiency. However, high machine accuracy is crucial for their use. FASTI meets this requirement through bilateral synchronization control in the clamping beam (with parallel accuracy < 0.1 mm) and CNC crowning in the folding beam. Only then can highly accurate workpiece geometry be achieved across the entire bending length of the machine.

Clamping beam tools:
1. Sharp-nose or goat's foot blades in C shape, divided across the full useful length of the machine.
2. Segmented tools tailored to match workpiece dimensions:
   - Set 1: Total length 225 mm, 6 segments in 5 mm steps, from 25 to 50 mm.
   - Set 2: One segment of 200 mm.
   - Set 3: One lateral goat's foot, right and left, each 100 mm.

Lower and folding beam tools:
Similar to clamping beam tools, with divided blades across the full useful width and segmented tools to match workpiece dimensions. Sets 1 and 2 are the same as in the clamping beam. All tools have a tensile strength of 1,000 N/mm². They are hydraulically clamped to the clamping beam, held by threaded pins on the folding beam, and loosely arranged in the lower beam.

This setup enables easy folding of reverse bends up to 40 mm width on four sides of a workpiece, as well as inner bends. Segmented series tools from FASTI allow flexibility, allowing you to start small and add to the stock as needed. "Old" and "new" tools are compatible, and if you work with multiple universal folding machines from FASTI, the same tools can be used for all. Universal use is a standard feature.

FASTI specializes in the development of multifunction tools for unique applications, leveraging their wealth of experience and know-how. With FASTI, you can be confident that nobody offers more in terms of versatility and capability.

In the control system, you have the option to choose based on a modular design. You can opt for a two-dimensional black-and-white representation in the basic version or add an additional 3D representation on a color LCD screen. No special programming knowledge is required. The interactive input is straightforward and intuitive, especially in graphic mode.

Simply input the material thickness and quality, workpiece geometry, and tools. The computer handles collision detection, ensures correct tool type and strength, and indicates process time and the effective length of the material to be bent. Clamping beam, folding beam, lower beam, and crowning values are automatically set, as well as the number and sequence of process steps and gauge positioning.

With proper preparation and machine operation, anyone can achieve excellent results.

Further optimization of daily work includes:

Network Integration: You can connect the machine control online to a PC or integrate it into an existing network.

Barcode Reader: Barcodes eliminate errors in reading and writing. You always have quick and secure access to your database and the required bending program.

Telediagnosis: Access telediagnosis by a service technician anytime via control and modem, ensuring prompt assistance when needed.

When you choose FASTI, you're not just getting a machine—you're acquiring the expertise and know-how of press braking technology and FasTrak speed folding. Even if it's not explicitly stated, seasoned professionals will recognize this in many details of the machine every day.

The following pages showcase the high flexibility and versatility of our universal folding machines. It's then that you'll realize your investment has paid off, and you've acquired a machine that's future-proof.

Here, you'll discover the machine's intrinsic value, understanding why you can rely on such high continuous accuracy for many years with a Fasti 225, even under constant use.

You have the option to select the most suitable technical and cost-effective tools from a wide range of options. As they say, the benefit lies in the tool itself.

You can also choose between two different controls, each equipped with its own accessories, ready to handle every task—whether it's working directly on the machine, preparing jobs via computer, networking, telediagnosis, and more.

Additionally, you have the flexibility to choose from four table versions, which can be retrofitted or varied later on. After all, today's needs may differ from tomorrow's bending requirements.
