171 The service life of the screw and drive nut combination can be calculated based on the thrust load and drive speeds The maximum travelling speed of the spindle units depends on the length of the spindle (see adjacent diagram). Calculating the feed rate of the carriage based on the drive speed at the input of the KGT: v = ​  n ∙p  _____  60000 ​ v ​ [ ​  m __ s  ​ ] ​= Feed rate n ​ [ ​  1 ___  min ​ ] ​= Drive speed p [mm] = Spindle lead Calculating the feed force of the carriage based on the drive torque at the input of the KGT: F = ​  M ∙ π ∙ η  _____ p  ​ ∙ 2000 F [N] = Feed force M [Nm] = Drive torque η [ ] = Efficiency (KGT 20x5: 0.8; KGT 20x20: 0.85; KGT 6 60 P20: 0.9) p [mm] = Spindle lead Linear Unit Art.
