Your Steam Turbine should be able to output only 1 packet at 32 GEU/p per tick, and insulated copper cable has a loss of 2 GEU/cable. (GEU being GregTech EU) I can't find the power requirement for the Bending Machine, but if it requires 30 GEU/t to operate, you can only afford to have 1 cable between your turbine and the machine. If it requires 32 GEU/t, you'll either need to hope that placing the machine adjacent to the turbine works, or you'll need 2 turbines to produce enough power. At which point, you'll probably need to do something to prevent overpowering the machine and having it explode.
At least, that's what I can make of your situation, based on the documentation. Hope I've helped.
