Stainless Lead Screw with Nut ( 8mm x 450mm) Pitch 4 (mm) IRF640 9-1ms pulses = fast oneLead screw is a linear motion mechanism that is used to transform stepper motor rotary motion into quick and accurate and precise linear motion positioning so you can move your CNC axis into the XYZ position required. Lead screws are self locking (they stay where they are with no need for braking mechanism). In addition to low cost, this make them better solution for vertical motion (Z direction) This is stainless steel precision trapezoidal (metric)
