- Higher throughput, less downtime
- Increased press availability
- Lower costs per part
The innovative hydraulic direct drive and radically new press design, combined with the new control platform, deliver unprecedented performance.
The FB one brings greater precision, speed and performance to fine blanking. It enables stroke rates of up to 100 per minute, shorter cycle times and outstanding repeatability – in conjunction with very high production speeds. Moreover, stainless and high-strength steels can be processed to excellent quality standards.
Welcome to the new world of fine blanking.
The FB one is based on a radically new press design.
The innovative drive cuts power consumption while raising productivity.
The press has been redesigned for far greater robustness. This has reduced springback in punch direction by more than 50 percent, and doubled the tool’s maximum tilting moment along the y axis. Traditional welded steel press frames are susceptible to cracks. These have been replaced by solid pillars with tie rods. The prestressed tie rods absorb the forces acting along the z axis, further reducing elastic springback. The more resilient design leads to longer press and tool service lives, and opens up new possibilities for improved tools.
The larger effective area of the hydraulic cylinder contributes to increased stiffness of mechanical press components. This offers greater freedom in terms of tool design and potential applications.
A further feature of the new press design is the reduced hydraulic fluid column, which results in greater stiffness and faster main-ram response time.
Timely detection of slow gas-pressure loss in the bladder accumulator minimizes production downtime.
The enlarged tool space and greater effective hydraulic area, plus the optional use of additional hydraulic forces, create new tool-design possibilities. Placing the tool-space adjustment mechanism in the top bolster (rather than the lower bolster, as in previous models) results in a larger opening for installing tools. This makes the tool space more accessible, or alternatively, allows the use of higher and stiffer tools.
The FB one is the most high-performance fine-blanking press on the market.
The FB one’s significantly more robust mechanical design makes the fine-blanking process more controllable, reliable, versatile, and cost-effective. As a result, the press can process stainless and high-strength steels to higher standards, in conjunction with less breakthrough shock and higher stroke rates.
The use of the latest components and the associated technical improvements lead to a better, more reproducible process.
Position of scrap chopper on the strip skeleton can be adjusted
This prevents the generation of loose slugs during scrap chopping, increasing process reproducibility.
Reduced impact forces prevent damage to press
The controllable, optimized stripping speed of the v-ring and ejection speed of the pressure pad lessen impact forces when the piston returns to rest position.
The adjustable pressing force of the rollers enables precise feeding of the strip, with far less risk of damage to the material.
More precise timing of valve actuation
Cutting-edge control and field-bus technology enables more precise timing of hydraulic valve actuation, in conjunction with higher stroke rates. This leads to less variation in the blanking process and greater reliability.
Enhanced process quality and technical enhancements lead to less downtime and higher system availability. This improves key technical and cost parameters:
