Numerical-control file grinding machine

The invention discloses a numerical-control file grinding machine. The numerical-control file grinding machine comprises a lathe bed, a working table, a grinding head device, a grinding head repairing device and a clamp device. The clamp device is arranged on the working table; the working table is arranged on the lathe bed in a sliding mode; the grinding head repairing device is arranged on the grinding head device. The numerical-control file grinding machine has the advantages and the beneficial effects that a grinding head feeding device can achieve rapid feeding and automatic control and has a certain elastic buffering effect, and the safety performance is improved; the clamp device can achieve rapid overturning of a file and pressing of the file through a panel turnover mechanism; the grinding head repairing device is convenient to adjust and wide in range, and automatic control is conveniently achieved; a warped plate type mechanism is wholly adopted in a grinding wheel dressing device; the structural design is reasonable, the interference of the grinding wheel dressing device in other parts of the grinding machine in the motion process can be effectively avoided; a diamond wheel is arranged in a sliding mode through a sliding plate frame; compared with axial motion of a grinding head, the diamond wheel is wide in range and is driven through a hydraulic motor, adaptability is good, and in the grinding process, the diamond wheel is not prone to breaking down.
