Frequently asked Questions

Q: How do you use the machine?
A: You put your sheet metal piece in under the clamp bar, switch on clamping, then pull the main handle (s) to bend the piece
Q: How is the clamp bar attached?
A: In use, it is held down by a very powerful electromagnet. It is not permanently attached, but it is located in its correct position by a spring-loaded ball at each end.  This arrangement lets you to form closed sheet metal shapes, and also to swap to other clamp bars quickly.
Q: What is the maximum thickness sheet it will bend?
A: It will bend 1.6 mm mild steel sheet in the full length of the machine.  It can bend thicker in shorter lengths.
Q: What about aluminum and stainless steel?
A: Yes, the Magnabend will bend them.  The magnetism passes through them and pulls down the clamp bar onto the sheet.
It will bend 1.6 mm aluminum in full length, and 1.0 mm stainless steel in full length.
Q: How do you make it clamp?
A: You press and temporarily hold the green "Start" button.  This causes light magnetic clamping.  When you pull the main handle it automatically switches to full power clamping.
Q: How does it actually bend?
A: You form the bend manually by pulling the main handle (s).  This bends the sheet metal around the front edge of the clamp bar which is held in place magnetically.  The convenient angle scale on the handle tells you the angle of the bending beam at all times.
Q: How do you release the piece?
A: As you return the main handle  the magnet automatically switches off, and the clamp bar pops up on its spring-loaded locating balls,  releasing the piece.
Q: Won't there be residual magnetism left in the piece?
A: Every time the machine switches off, a short reverse pulse of current is sent through the electromagnet to de-magnetize both it and the piece.
Q: How do you adjust for metal thickness?
A: By altering the adjusters at each end of the main clamp bar.  This alters the bending clearance between the front of the clamp bar and the working surface of the bending beam when the beam is up at the 90° position.
Q: How do you form a rolled edge?
A: By using the Magnabend to wrap the sheet metal progressively around a length of ordinary steel pipe or round bar.  Because the machine works magnetically it can clamp these items.
Q: Does it have pan-brake clamping fingers?
A: It has a set of short clamp bar segments which can be plugged together for forming boxes.
Q: What locates the short segments?
A: The plugged together segments of clamp bar must be located manually on the piece.  But unlike other pan brakes,  the sides of your boxes can be of unlimited height.
Q: What's the slotted clamp bar for?
A: It is for forming shallow trays and boxes less than 40 mm deep.  It is available as an optional extra and is quicker to use than the standard short segments.
Q: What lengths of tray can the slotted clamp bar fold?
A: It can form any length of tray within the length of the clamp bar.  Each pair of slots provides for a variation of sizes over a 10 mm range, and the positions of the slots have been carefully worked out to provide all possible sizes.
Q: How strong is the magnet?
A: The electromagnet can clamp with 1 ton of force for every 200 mm of length.  For instance, the 1250E clamps up to 6 tons over its full length.
Q: Will the magnetism wear out?
A: No, unlike permanent magnets, the electromagnet cannot age or weaken due to use.  It is made of plain high-carbon steel that depends solely on an electric current in a coil for its magnetization.
Q: What mains supply is needed?
A: 240 volts ac.  The smaller models (up to the Model 1250E) run from an ordinary 10 Amp outlet.  Models 2000E and up need a 15 Amp outlet.
Q: What accessories come as standard with the Magnabend?
A: The stand, backstops, full-length clamp bar, a set of short clamp bars, and a manual are all included.
