Longitudinal rail
The longitudinal rail is the main part which can ensure stable running of the machine. It consists of two parallel high precision linear rail. High precision racks are inlaid in-between the two linear rails. The rack is measured by parameter-CP (bottom clearance between gear and rack) which can reduce accumulated error caused by transmission of gear and rack, ensuring the running stability and transmission precision of the cutting machine. The working precision meets the standard DIN8523.
CP 10 rack: processing precision: level 7; processing error: 0.06mm/1000mm.

Longitudinal drive
The drive is combination of high rigidity precise gear reducer from NEUGART, Germany and FAGOR AC servo motor. It can realize longitudinal machine movement by flexible meshing of gear and rack.
Horizontal drive
There are two sets of horizontal drive units. The main drive and auxiliary drive carries out movement in the same direction according to a certain proportion, so that the optical path will form constant optical system. The drive is combination of high rigidity precise gear reducer from NEUGART, Germany and FAGOR AC servo motor. It can realize horizontal machine movement by flexible meshing of gear and rack.
Aplantic compensation device
The horizontal optical path is in motion during cutting. So the focusing of optical system will be unstable caused by the constant change of the horizontal optical path, thus affecting the cutting quality of the workpiece. This cutting machine adopts aplantic control technique. A group of aplantic compensation units are added on the horizontal moving direction, keeping the optical path length during horizontal movement, thus ensuring the cutting quality.
Cutting torch lifting unit
The cutting torch lifting unit adopts double linear rail guide and precise ball screw as the transmission method, so that the torch lifting is quite stable. It also has dual protection of mechanical position limitation and soft limit to ensure cutting quality and lifting safety of laser cutting torch.
Longitudinal drag chain unit
There is many service cables and air sources which should be lead into the cutting machine along its longitudinal and horizontal moving direction. Because there are more longitudinal cables and gas pipes, the longitudinal movement has quite large moving load which will reduce the running stability and reliability of the machine. So, the longitudinal drive system adopts drag chain servo unit to ensure the longitudinal and horizontal running stability.
