Gantry structures, Y axis use simultaneous dual motor and drive, X, Y, Z axis with circular rail (formula type linear guide can be chose), steady transmission, high precision.

By way of motion accuracy experiment of rolling linear guide pairs and combining with theoretical analysis this paper carried out a deep study on the motion accuracy of guide pairs.

X-shaft guide rail applies the support structure of two guide rails, selects imported heavy-duty roller straight-line guide rail, and has various heavy load-bearing sliding blocks.
