Broaching machines

  • Internal broaching machines
  • Surface broaching machines
  • Special broaching machines: pot broaching, broaching machines for turbine discs and broaching machines for blind holes
  • Vertical and horizontal execution
  • Electromechanical drive or hydraulic drive
  • 40 kN to 2.000 kN pulling force
  • 800 mm up to 5.750 mm stroke
  • 0,5 up to 60 m / min. broaching speed
  • 250 / 320 / 400 / 500 / 630 / 800 / 1.000 mm tablewidth

 

Electro-mechanical drives are increasingly replacing the hydraulic ones considering the better overall equipment efficiency and the improvement of quality results achievable. In addition, a plurality of advantages such as:

 

  • No hydraulic oil or aggregates
  • No cooling systems for hydraulic oil
  • Noise protection only for the machine
  • Electro-mechanical drives provide constant broaching speed regardless the broaching effort
  • Hydraulic is compressible, broaching quality is not as good in comparison width electro-mechanical drives
  • No danger because no high pressures by hydraulic oil
  • High live time in comparison width hydraulic main drive
  • Less repair and maintanane efforts
  • Better energy balance (energy is only requested when broaching, hydraulic is every time in function)
  • Lower insurance costs and no pollution because no hydraulic oil
