CNC-2000/2500/3000 adopts a CNC system, Four-Axis linkage, which can process the circular stone slab, roman column, numeral, letter, Chinese characters, and other designed shapes. 1. It has a heavy load-bearing structure, four orbits on each upright column, adjusted the balance by the rollers, with less friction and higher precision. 2. The left and right frames achieve synchronized lifting by steering equipment on the upper frame. The lifting accuracy increased by the combination of the lead screw and double nuts. 3. Cantilever part, firstly the lead screw and pole adjust the distance of guide wheel, guide wheel is controlled by CNC. Secondly, in order to make the diamond wire rope cutting direction coincidentally, the reducer controls the guide wheel rotating angle. 4. Worktable is running by lead screw and railway. 5. There has an automatic alarm if the wire breaks. 6. Aluminum wheel diameter is 1600mm. One flywheel slide through sheave, oil pump control rope tension.
