Short description
The machine includes the complete mechanics for three-dimensional movement. The linear
carriage-movement takes place via threaded spindles, powered by step motors. Two drives are used
on the x-axis. The activation of the step motors, in order to operate every single axis, is done by
using further interfaces. This operating description will show you how to install, operate and service
a CNC- portal system.
