Why are the large guide rails on the machines Y axis exposed?
That is a question we are often asked, mainly because our competitor’s like to hide their small rail and drive systems from plain view. First of all, we use very large 45 mm THK precision ground rails that are specially treated to prevent corrosion (AP-C), even if moisture is directly applied to them. Secondly, the machines include splash shields that prevent water and other residues from being splashed into the rail areas as a result of machining operations. It should be noted that even bellow covers do not prevent water from coming in contact with the guide rails since the bellows themselves do not form a tight seal. We do use bellows on the X axis strictly for cosmetic purposes, since the guide rails on the X axis are also specially treated to prevent corrosion!
