1. Positioning accuracy
In terms of accuracy, the identification of linear guide drive mechanism reduces the problem of interpolation lag. The positioning accuracy, reproduction accuracy and feedback control through position detection are easier to achieve than rotary motor+ball screw
2. Repetitive precision comparison
The transmission mechanism is simple, reducing the problem of interpolation lag. On the contrary, the clearance of the lead screw is easy to affect, so the linear guide rail is easier to realize.
3. Speed comparison
Generally, because of the centrifugal force, the servo motor will be subject to greater stress during high-speed operation, so the speed and output power are limited. Relatively speaking, the linear guide has no restrictions and no mechanical loss, thus improving the transmission speed.
