The invention discloses a double-side grinding machine with an upper disc and a lower disc provided with turning tool rests. The machine is mainly used for automatic accurate grinding of various high-precision crystal planes in the electronic optical industry. According to the main technical scheme, a lower disc turning tool rest part is fixedly connected to a spindle box of an upper disc part; the upper disc part is fixedly connected with a base of a rack part; an upper disc turning tool rest part is fixedly connected to a base of a lower disc part; the lower disc part is fixedly connected with the base of the rack part. As is proved by tests, the grinding machine fundamentally eliminates the phenomena that time and labor are wasted and quality cannot be guaranteed when an upper disc and a lower disc of an original double-side grinding machine conduct turning, and quality can not be guaranteed; production efficiency is effectively improved, cost is reduced, and the requirement for large-scale production is met.
