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
