Features

Maximum tool life time:

  • Ram guides in the strip level to avoid displacements of the punch when entering the bottom die in case of off-centre load
  • Thermally neutral ram guides for the compensation of horizontal expansion
  • Automatic ram height adjustment during operation for the compensation of displacements of the ram in BDC due to speed and thermal influences
  • Closest tolerances in the whole drive to reduce vibration and breakthrough of the ram in BDC

 

 

High performance:

  • Multi-row cylindrical roller bearings with minimal bearing play
  • Mass counterbalancing system in vertical and horizontal direction with automatic adjustment after a stroke change
  • Short, torsion-resistant main shaft  in transverse design
  • Pressurised central lubrication system for less wear

 

 

High accuracy:

  • Lever system to divide the actual punching force
  • Ram height adjustment during operation
  • Main and connecting rod bearings with little clearance
  • Pressurised central lubrication with high volume for thermal stability of the machine

 

 

 

Reliability:

  • Lever system to divide the actual punching force
  • Pressurised central lubrication with high volume
  • Main and connecting rod bearings with little clearance
  • Short breaking angle for a safe process 

 

 

 

Long machine life time:

  • Lever system to divide the actual punching force
  • Pressurised central lubrication with high volume
  • Adjustment spindles of the ram height adjustment arranged outside of the power flow

 

 

 

 

Versatility for many applications:

  • Stroke adjustment
  • Small and big strokes to select for every application
  • Wide speed range
