Hard to manipulate and hold a complicated shape like the body of an electric motor?


When the body of an electric motor has been cast and leaves the mould, it still needs to be machined for the holes and flanges. So there is an immediate need to manipulate and position the body.

Did you know that the “Diaphragm technique” is an easy and cost effective way to do just that?

It uses plates that have been (laser-) cut to fit the profile of the motor body, but their profile has been adapted to only touch the places where one wants it. These plates are placed in opposition to form pairs that clamp the body from opposite sides. Finally these pairs of plates are stacked to obtain a tool with a strong holding force allowing an easy and save manipulation of the body and a solid and precise holding during the machining.

Example of the firm and precise holding of the body of an electric motor
by means of a tool consisting of “Diaphragm” plates.
– Pairs of opposite plates are stacked and assembled with bolts to form a tool
– Left shows the open position, and right the closed position, both assured with bolts
