Press Brakes

The Press Brakes, HPB780 series of ATM are fast and exceptionally accurate bending brakes for precise sheet metal forming through defined bending and edging. The presses open all possibilities to their users – in compliance with currently binding safety regulations. Serial equipment allows achieving such productivity and precision.

Our Hydraulic Press Brakes were designed by latest tehnology`s latest developments and in according to customer needs with in mind working easily, security, safety and large bending capacity.
Frames and rams are steel – welded construction and were manufactured to be rigidity most durable on stroke workings. The walls were manufactured by double plate boxing to increase the resistance except under the 250 tons capacities.

General Properties

  • Hydraulic cylinders are designed and manufactured from solid steel billet and honed precisely.
  • Pistons are steel forgings, hardened, chrome plated, precision ground and micro polished for years of trouble-free service.
  • Compact hydraulic block with pressure relief valves for safety.
  • The torsion bar and stopper system inside cylinders enable parallel move of top beam and accurate bend angle at both ends of the work piece.
  • Pre-fill valves enable top beam to approach the work piece rapidly and return rapidly after bending.
  • Tilting of upper beam for conical bending.
  • Bending is performed at slow speed according to CE norms.
  • Hardened ram slide ways working with low friction and wear resistant material and optimum lubricant material and optimum lubrication grooves.
  • Pressure switch limits bending force during bending and active automatic return of top beam to top dead centre.
  • Top quality Busak Shamban seals and o-rings for long duration problem free operation.
  • High quality hydraulic fitting High pressure and silent Rexroth hydraulic pumps.
  • PLC based compact and reliable electrical system with ventilating electrical cabinet.
