Who is the ERB 20 electric bender for?
The ERB 20 electric bender is recommended for the following professional profiles:
-
Metalworking shops and workshops: bending sheet metal for the manufacture of cabinets, profiles, and casings.
-
Machine and metal container construction: making 90° bends and various angles on standard sheet metal.
Not suitable for: bending pipes or hollow profiles (machine dedicated to flat sheet metal: specific pipe bending machines are needed for pipes).

Frequently Asked Questions
What sheet metal thickness can it bend?
See "Bending capacity" in the technical table: typically up to 3-6 mm on mild steel.
The capacity refers to nominal S235 steel. For stainless steel or high-strength steel, the actual capacity may drop to 60-70% of the declared value.
What is the useful length?
The bending length is indicated in the technical table (typically 1,000-3,000 mm).
The useful length determines the maximum size of the piece that can be bent in a single pass. For longer pieces, larger machines are needed.
What bending angles are possible?
Typically from 0° to 135° with a standard V punch. Check the technical data sheet.
For 90° bends or specific angles, dedicated punches and dies can be used. Krollit supplies original Bernardo bending tools.
Does the machine have CNC control?
Professional models offer CNC control for automatic angle and backgauge positioning.
CNCs reduce setup times in series production and offer repeatability in the finished product.
What power supply does it require?
Hydraulic bending machines require a 400 V three-phase power supply; see "Motor power" for the precise data.
Check for an adequate three-phase line and size the cables according to the nominal power of the hydraulic unit's motor.
