Precision pressbrake offers faster bending

Precision 350kN press brake features a reluctance hydraulic motor that achieves higher bending speeds - of up to 25mm per second - than most conventional hydraulic machines.

LVD introduces the PPRM precision press brake featuring a reluctance hydraulic motor that achieves higher bending speeds than most conventional hydraulic machines.

The PPRM delivers working speeds of up to 25mm per second at reduced load, depending on application and safety requirements.

The press brake is ideal for bending small- to medium-sized high precision parts.

The PPRM is a 350kN machine with a working length of 1250mm.

The machine's high production capacity is attributed to a simple working principle.

The press brake ram is supported by springs and uses two single-acting hydraulic cylinders.

Each hydraulic cylinder is directly connected with a hydraulic pump driven by a servomotor.

There are no switching valves in the hydraulic circuit and no lapsed time in the cycle ram because of mechanical movement of the valves.

The result is higher production rates and greater machine reliability.

The PPRM is designed for efficiency and long production life.

The press brake consumes on average 30 percent less energy than conventional hydraulic press brakes.

There are no mechanical components such as ball screws or gearboxes to wear, and no friction in gearboxes or balls screws which can reduce accuracy.

The PPRM's bending force is proportional with the torque of the servomotor, which can easily be controlled for the application.

The bending force can be reduced to 5% of the maximum load, allowing the user to work with small tools without risk of damage.

The machine features a 100mm throat allowing access to both ends of the ram and bed for tool loading.

The machine provides an open height of 385mm, ram stroke of 185mm, back gauge X-axis travel of 500mm and R-axis of 200mm.

The press brake is equipped with LVD's easy-to-use CADMAN Express CNC control, a Windows based system with a user-friendly interface for all levels of programming experience.

The control features an Intel Pentium microprocessor, 20GB hard disk drive, CD ROM and 12in TFT screen.

CADMAN Express provides a number of automatic features, including automatic calculation of bend allowance, automatic selection of tools based only on material thickness, and automatic calculation of lower dead point (Y-stroke).

It features graphical representation of tools, program overview in editor mode and in production mode, graphical representation of tools and backgauge in production mode, and an easy method for adjusting correction angle and correction of bend allowance.

The PPRM requires minimal floor space and enables ergonomic operation from a sitting position.

Compact and portable, the PPRM can be easily relocated using a forklift, making it ideal for cell manufacturing.

The machine is supported on three rubber mounting pads that facilitate easy installation and relocation.

LVD is a leading manufacturer of metalforming equipment/sheetmetal working machine tools, including turret punch presses, laser cutting machines, press brakes, guillotine shears, press brake tooling, and programming software.
