1. The CNC cylindrical grinding machine is suitable for batch production of cylindrical parts grinding with high performance-to-price ratio.
2. The electrical system is controlled by SIEMENS 808D CNC control system and is driven by the CNC servo driver and servo motor. Worktable longitudinal travel and wheel head cross traverse which with the high infeed accuracy are realized by the servo motors via the ball screw transmission. With the touch screen and human-machine interface, the machine is easy to operate.
3. Configured online automatic measuring instrument .
4. The machine is simple and easy to operate. After simple training, it can be operated easily. By setting the parameter of longitudinal grinding or plunge grinding via the touch screen, an auto-grinding for the different workpiece is realized. With the function of worktable trip-stop, the machine can grind more than one journals of one workpiece automatically. The process parameter of more than one journals can be set discretionary for long grinding of plunge grinding.
5. With the function of wheel dressing and compensation automatically.
6. Wheelhead spindle is supported by three bushing hydro-dynamic bearing, and high precision hydro-hynamic static bearing is also available for the user.
7.Timing provision of lubrication for machine moving parts according to program designing. Automatic lubrication of all moving parts. Tailstock has two ways: hydraulic and manunal.
