Why choose SNR heavy gantry machine?


1.The whole gantry frame is made by annealing treatment, not deformed.
2.New type THC, Build-in TBI high precision imported Ball Screw.
3.The structure of motor install adjust seat is the same with that of Messer.
4.Use 38 KGS steel rail.
5.Add guide rail brush, extended service life.
6.Before install the rails and racks, we firstly milled the slots by milling machine, not install directly, thus the accuracy would be highly improved.
