| Detailed functions of the electrical software control system in the control cabinet | The powerful hardware system is compatible with mainstream control systems on the market, without the need for additional servo cards and expansion cards. The factory comes standard with computer graphics based automatic programming Windows XPcad software, which can perform pitch compensation and reverse clearance compensation on X, Y, U, and V axes, solving the problem of low precision for large taper angles and achieving precise cutting of upper and lower irregular shapes. And it can display the coordinates of X, Y, and U.V4 axis movements in real time. 5-axis CNC with advanced tool repair function, capable of cutting one, repairing three, repairing seven, and achieving high smoothness. More advanced PCI interface, high compatibility, four axis linkage machining, upper and lower irregular shapes, making taper machining fast and easy. Capable of processing straight lines, arcs, non-circular curves, gap compensation, reversing, scaling, rotation, symmetry, and automatic centering. The system has functions such as power-off protection, wire breakage shutdown, and end shutdown. | ||
| Main outstanding performance indicators | X,Y,U,V,Z， 5-axis CNC, slow wire machine tool main structure and casting process, using high rigidity HT300 resin sand casting casting, the machine tool has high rigidity and low vibration. The highest cutting efficiency is greater than 200mm2/min, and the optimal surface roughness is less than Ra ≤ 0.8. The X, Y, U, V, and Z axes all use Taiwan Shangyin linear guides and high-precision double nut ball screws, with high-precision cutting of less than ± 0.003mm and continuous cutting of 100000 mm2 molybdenum wire loss of less than 0.005mm. The whole machine adopts Japanese advanced NSK bearings, with high precision and long service life. The electronic components of the whole machine are all from Germany, Switzerland, Japan and other leading brands. Yunsi has eliminated the old-fashioned induction switch control and adopted encoder direct control, achieving precise positioning. The software can perform pitch compensation and reverse clearance compensation on X, Y, U, and V axes, solving the problem of low accuracy due to large taper angles and displaying the coordinates of X, Y, U, and V4 axis motion in real time. Adopting a slow walking servo automatic wire tensioning structure, the tensioning force can be automatically adjusted according to different processing states | ||
