Ease of use combined with state-of-the-art technology go hand in hand, improving productivity. The touch screen gives access to the proven Delem user-interface and enables direct navigation between programming and production. Functions are directly located where you need them, offering optimised ergonomics throughout the application. The DA-66T offers 2D programming that includes automatic bend sequence calculation and collision detection. Full 3D machine set-up with multiple tool stations giving true feedback on the product feasibility and handling. Highly effective control algorithms optimise the machine cycle and minimise set-up time. This makes using press brakes easier, more efficient and more versatile then ever. -Baykal machine frames are manufactured from hot rolled steel sheets of Fe 520. The two side frames are obtained from the same sheet to ensure the same elasticity under stress. The ram and table are also manufactured from Fe 520 steel and are designed to avoid deflection. Pedpfx Ajxl Ddhjdierd -The hydraulic cylinders are manufactured from high resistance steel chromium plated & ground to size. Cylinder pistons are lapped to ensure longevity of the hydraulic seals -The hydraulic unit consists of electronically controlled proportional valves with independent closed loop control of the two cylinders providing full synchronous control. -German manufactured Laser Safety Guard System mounted at each end of machine ensuring correct interfacing and operator safety whilst in operation. The Laser system is designed so each guard will slide up or down to allow for many different types and sizes of tooling enabling safety at the appropriate points as required by the Australian standards. Manual height adjustment with scales and lock for easy positioning. -Sliding front sheet supports enable a wide range of material sizes to be aligned and supported at the correct required width and height. The sheet supports are mounted on precision linear guides for ease of movement. This design can also be adjusted vertically to support material with return bends. -Ram positions (Left & Right) are obtained from independent linear encoders whilst monitoring and adjusting proportional valves. This produces a closed loop system, with guaranteed beam positioning of +/- 0.01mm (Y1 and Y2 Axis) -Accuracy is further ensured by mounting the linear encoders on a C-frame connected directly to the Bed, rather than the side frames. This ensures that deflection of the side frames and uneven loads have no effect on Beam position.
