HRB-4 series
- Accurate, ease of operate, fastest roll bendings
- Flat zone of the sheet edges is minimised
- Pre-bending, conical bending and ellipse bending can be done easily
- Double pre-bends (both ends) in one pass
- Hydraulic and electrical systems have been safeguarded from overloads and require minimum maintenance. Hydraulic and electrical components are modular and designed according to world standards.
- The sheet is controlled by tightening of top and bottom rolls
- Most suitable bending operation for CNC applications. More efficient for cycle times
- User friendly operations without dependence to operator competence.
