CNC 4 Guide way Giant Lathe

4 Guide-way CNC Giant Lathe is a special type of flat bed lathe. It has one wide bed and 2 pairs of guide ways. Its tailstock and steady rests are placed on the pair of guide ways at the rear side. Thus, we would build the carriage across the 4 guide ways (called full length cross slide) as standard model; this model could stand for very heavy duty machining and has full cross slide travel.
Besides, we could build its carriage on one pair of guide way at the front side (called half length cross slide). In this option, the carriage wouldn’t interfere with steady rests and its tailstock; it’s very good at outer diameter machining at one time without removing steady rests.
