Motor selection for metal cutting job

[Abrabaracurxis]

Hi,

i need to select a motor to cut small diameter pipes (less than 5mm) 1 mm thickness. i have to do around 400-500 cuts per hour what parameters do i need to consider in the selection? or better by what criteria should i google... dont really know what to look for ...

... and i dont have much experience in this kinds of jobs so this probably sounds stupid but if i fix several pipes togther can i cut several at once? (im thinking to use some kind of coolant)

thanks

juan

Yep! What jraef dug up was what I expected. Essentially a mechanized pipe cutter. (external cutter)

The shear in the 2nd post does 40-70 parts per minute (ppm). You said 2-3 pipes in 9 second cycles, thats 20 ppm.

Good point; if he needs a cutter that fast just to whittle down his scrap pile, it must be an enormous pile already, and presumably growing at some substantial fraction of 20 ppm.

It seems to me that the first thing to be settled is the cutting tool. The manufacturer of the tool will spec the speed, tool pressure, or shaft torque. From that, the speed and torque and then hp will naturally follow.

In fact, the choice of cutting tool will define whether multiple tubes can be gang cut or not.

well thanks DickDV im getting in touch with the manufacturers...
it happens that i was mistaken there were no problem with the burr because there is no burr. So, i double checked and that is because they cut with abrasive disc... the local providers recomended to use a friction cutter or and abrasive disc to avoid the burr... i dont know how much will the shear afect the roundness and how much the proces can tolerate (im working on that)

the good thing is i got a lot better idea how to deal with the motor now... and ideas in general.
