Main specification

1. Automatic recognition of power in machine and work piece, the processing is both quick and good
2. Slow returning core, boosted by barrow, imporving the apprearance of the angle.
3. The whole operation is in the computer, simple, quick and correct
4. Picturized programming system: draw and modify on the stereo pipe image on the screen, makes the operation simple, quick and correct
5. Rebound test: comparison test on the features of lots of pipe materials
6. Single-step debugging function- a careful observe on the deformation of the pipe material during the trail manufacture of dies.
7. Automatic drawing of the graphics of dies-clear help to develop new products
8. Over-all inspection: hydraulic/electrical circuit/ driving systems, adsence of phase in motors/inversion, voltage, temperature, oil pressure, and automatically diagnose the troubles
9. Passwords, keys, working hours/ recordings of quantities, are applied to management of production
