    Torque on lead screw based on psi

    Oh heck! I didn't factor that in! It'll just be silicone on polyethylene.. sound be easy to find.. :confused:

    Torque on lead screw based on psi

    Thanks billy for the link! I think I have it solved! I used the square lead screw because it seems the most efficient.. The axial torque seems to be .184 kg*cm.. Seems low but math doesn't lie! Hopefully it works..

    Torque on lead screw based on psi

    So in a cnc machine, the screw that drives the x,y,z axiis are called "lead screws". I am constructing a machine that displences fluid at percise volumes. It will be essencially a seringe with one way valves coming in and going out. To open the "check valve" it requires at least 1.5 psi. If I am...
