With thousands of HF-type press brakes installed throughout Europe, Amada is bringing higher accuracyto its mid-range line-up for the first timewith the company’s new auto-crowning device. Previously only available on high-end press brakes such as the Amada HG, the new HRB Auto Crowning mid-range model responds directly to customer demand.

The HRB Auto Crowning press brake features a new system, compensating for deflections in the upper and lower beam after the application of pressure. There is also an extended open height of 520mm and stroke of 250mm for all standard-stroke models. The new auto crowning device is CNC controlled through the AMNC 3i control in conjunction with the DigiPro digital protractor device, making it suitable even for non-skilled operators.

Amada’s auto-crowning device brings many advantages to customers who need higher accuracy, in addition to a stable and reliable bending process. Production of kitchen equipment, furniture, electronics and assembly components are just some examples of parts that can benefit from these new features.

The HRB Auto Crowning machine can also be equipped with an optional automatic sliding foot pedal. When a program has several bending stations along the beam, there is no longer any need to keep moving the foot pedal manually. It is not uncommon for some press brake operators to move the foot pedal 100 times a day, which over a year equates to a lot of wasted time. Amada’s sliding foot pedal allows automatic movement, boosting productivity.

The machine is available through a wide range of sizes, from 50 tonnes/2 m up to 220 tonnes/4 m, including the long-stroke versions, which increase the open height from 520 to 620mm.

The new LVD Dyna-Press 60/20 high-speed electric-drive press brakeprovides 2 m of working length and a five-axis back-gauge to handle a wide range of applications at bending speeds up to 25 mm/s. A 60/20 Pro model is further equipped with LVD’s Easy-Form laser system for greater control of the bending process to achieve high output at a high level of quality. The Pro model also offers an optional custom-made crowning system.

Dyna-Press press brakes consume low amounts of electricity and deliver fast cycle times to bend more parts per minute, more efficiently, at a lower cost per part. A streamlined design uses two heavy-duty ball screws to drive the force transmission from the servomotors to the pressing force of the ram. Fewer components means less maintenance.

Operators can use the machine for air bending, coining, hemming and bottoming. Furthermore, Dyna-Press 60/20 offers flexibility in tooling, accepting universal, Wila or US style-punches and universal, LVD or US style-dies. The Pro version offers pneumatic Wila clamping for the European market and hydraulic clamping for the US market.

LVD’s 60/20 Pro is available with a crowning system custom-made for each machine, distributing the appropriate force to ensure the bend angle remains consistent over the full length of the part. Like all Dyna-Press models, LVD says that the 60/20 is easy to operate with minimal training. The 15-inch Touch-B touchscreen control features an intuitive graphical display. Operators can create 2D designs and simulate in 3D on the screen, while the controller is compatible with LVD’s CAM software, CADMAN-B.

Dyna-Press press brakes are available in 24, 40 and 60 tons.
