Hydraulic press / brake
max. 3 000 kN | PPM series
The PPM press brake line is our hydraulic conventional line, ranging from 45T to 350T with bending lengths of 1600mm up to 4300mm. These high precision machines have a mechanical depth-stop integrated in both hydraulic cylinders.
Ram parallelism is guaranteed by a sturdy solid torsion bar which connects both sides of the ram.
The bending accuracy is 0.01mm and we offer a motorized backgauge on all machines. All machines use standard European top style tooling and Haco style or European style bottom tooling.
Both mechanical depth stops are integrated inside the hydraulic cylinders. This keeps the depth stops dust free and well lubricated by the hydraulic oil. We guarantee a 0.01mm bending accuracy with this system, perfectly suited for air bending
Most competitors offer systems which shut down the oil flow to the piston when a micro switch is reached. These systems are very sensitive to the temperature and viscosity of the hydraulic fluid and will mostly only guarantee a 0.025mm bending precision. Not accurate enough for air-bending.
The stroke length and speed change point can be set very easy with an adjustable cam system on the side of the ram. The machines can be purchased with a motorized backgauge.
