FAQ

MAGNABEND™ frequently asked questions

QHow do you use the machine?
AYou put your sheetmetal workpiece in under the clampbar, switch on clamping, then pull the main handle (s) to bend the workpiece

QHow is the clampbar attached?
AIn 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 form closed sheetmetal shapes, and also to swap to other clampbars quickly.

QWhat is the maximum thickness sheet it will bend?
AIt will bend 1.6 mm mild steel sheet in the full length of the machine. It can bend thicker in shorter lengths.

QWhat about aluminium and stainless steel?
Aes, the Magnabend will bend them. The magnetism passes through them and pulls down the clampbar onto the sheet.It will bend 1.6 mm aluminium in full length, and 1.0 mm stainless steel in full length.

QHow do you make it clamp?
AYou 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.

QHow does it actually bend?
AYou form the bend manually by pulling the main handle (s). This bends the sheetmetal around the front edge of the clampbar which is held in place magnetically. The convenient angle scale on the handle tells you the angle of the bending beam at all times.

QHow do you release the workpiece?
AAs you return the main handle the magnet automatically switches off, and the clampbar pops up on its spring-loaded locating balls, releasing the workpiece.

QWon't there be residual magnetism left in the workpiece?
AEvery time the machine switches off, a short reverse pulse of current is sent through the electromagnet to de-magnetise both it and the workpiece.

QHow do you adjust for metal thickness?
ABy altering the adjusters at each end of the main clampbar. This alters the bending clearance between the front of the clampbar and the working surface of the bending beam when the beam is up at the 90° position.

QHow do you form a rolled edge?
ABy using the Magnabend to wrap the sheetmetal progressively around a length of ordinary steel pipe or round bar. Because the machine works magnetically it can clamp these items.

QDoes it have pan-brake clamping fingers?
AIt has a set of short clampbar segments which can be plugged together for forming boxes.

QWhat locates the short segments?
AThe plugged together segments of clampbar must be located manually on the workpiece. But unlike other pan brakes, the sides of your boxes can be of unlimited height.

QWhat's the slotted clampbar for?
AIt 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.

QWhat lengths of tray can the slotted clampbar fold?
AIt can form any length of tray within the length of the clampbar. 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.

QHow strong is the magnet?
AThe electromagnet can clamp with 1 tonne of force for every 200 mm of length. For instance, the 1250E clamps up to 6 tonnes over its full length.

QWill the magnetism wear out?
ANo, 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 magnetisation.

QWhat mains supply is needed?
A240 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.

QWhat accessories come as standard with the Magnabend?
AThe stand, backstops, full-length clampbar, a set of short clampbars, and a manual are all supplied.
