Press Brakes

HPB-E Servo/Electric CNC and HPB-H Hybrid CNC Press Brakes

Huge energy consumption savings for fabricators and production floors using press brakes as compared to their hydraulic cousins.
The HPB-E and HPB-H Press Brakes offer quick setups and consistent bend angles, especially for air forming, the bending method preferred for these machines. With the precise linear bearings and the sliding front support arms which move right and left on the rail, the sheet can easily be controlled by the operator from the front. Also, the length of the parts can be measured by means of the ruler mounted on the front support arms. The sheet can be fixed from the front side with the aid of the flip stop which is mounted inside the T slot.

CNC Controlled Backgauge System

The machines begin with a steel body mono bloc welded of ST44 material, which is rigid against bending and high tension. These brakes come standard with 6 axes (Y1, Y2, X, R, Z1, Z2) with a CNC controlled backgauge system with 4 axes (X, R, Z1, Z2). Top and bottom tools are hardened and ground (835 mm length) and offer an easy clamping top tool holder system. The DELEM 66T CNC controller is run on a 3D color graphics display and offers offline software as well as programming at the machine. The electric panel and its cooling system are designed and manufactured by SIEMENS electrical and automation products in compliance with the CE regulations.

The HPB-E and HPB-H feature the new generation DA-Touch controls offering an even higher grade of efficiency in programming, operation and control of today’s press brakes. 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 optimized 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 optimize the machine cycle and minimize set-up time. This makes press brakes easier, more efficient, and more versatile than ever.

CNC Controlled Motorized Crowning System

In the HPB-E servo/electric press brakes, the CNC controlled 4 axes (X, R, Z1, Z2) backgauge system is run exclusively by AC servo motor. Crowning is no longer necessary due to the consistent pressure across the beam. There is no throat in this machine. Full length bendings are done between the feet. The beam downward movement is performed with the aid of belts, and its return is performed with the springs, producing only 63 dB of sound level and making these the quietest among the sheet metal bending machines.

Combining the Power of Electric and Hydraulic Saves

In the HPB-H hybrid press brakes, the CNC controlled 4 axes (X, R, Z1, Z2) backgauge system is run by AC servo motor paired with a highly-efficient, minimum maintenance, closed-loop HOERBIGER hydraulic system. This combines the accuracy of an electric press brake with the power of a hydraulic system. The included CNC controlled motorized crowning system saves time and material.

Small but powerful single axis press brakes

Looking for hydraulic workshop press brakes with up to 200t of pressure and a footprint of only 7 x 4’? Look no further than the HPA-P line up of manual press brakes now offered by KAAST Machine Tools. They introduced the HPA-P series to market at the Fabtech tradeshow in Atlanta in early November of 2018. As the only small hydraulic press brake at the show, the HPA-P caught the eye of operators and engineers alike. Since their debut, these small but powerful brakes have garnered a great deal of admiration from job shops, prototyping facilities, and production facilities.

These high-quality European built machines are a cost-effective solution for small bending jobs and prototyping. The HPA-P hydraulic workshop press brakes offer 100 and 200 tons or working pressure providing steady smooth operation with manual and two-handed working controls at a much lower price point than their CNC cousins. The one-step pressure adjustment and one-step stroke adjustment simplify what can be a daunting task.

The limit switches keep cycle times to a minimum while the choice of 40”, 60”, 80”, or 100” of working area, and an adjustable table height offering up to 16” of daylight, make for easy manipulation of the workpieces. There are guide columns on either side of the center hydraulic center help to ensure steady and even pressure across the table.

Model HPA-P comes with a top press brake die and holders and a standard multi-V bottom die, both of which can be replaced with any standard or custom press brake tooling. Options include segmented tooling, backgauge, bottom table with special T-slots, working with a foot pedal, and a high-speed working system.
