High-precision grinding machine with double grinding heads

The invention discloses a high-precision grinding machine with double grinding heads. A working head part and two grinding head parts are arranged on a base. The two grinding head parts are symmetrically mounted on two sides of the working head part. The working head part and the grinding head parts are controlled by a control box to operate. A double-head chuck seat is arranged on a working head base. A double-head chuck is mounted in the double-head chuck seat. The double-head chuck is driven by a working head servo motor through a conveyor belt. A dressing seat is arranged on one side of the double-head chuck seat. After a workpiece is mounted on the double-head chuck seat, two ends of the workpiece are exposed, grinding wheels are driven by electric spindles of the grinding head parts on two sides of the working head part so as to grind the workpiece respectively. The processing paths of the two grinding wheels are controlled individually by an NC program in the control box, and therefore, different grinding operations can be conducted on the two ends of the workpiece, grinding of the two ends can be completed through one-time clamping, the processing efficiency is relatively high, and the grinding precision is relatively high.
