The invention relates to rubber bar batch cutting machining device and cutting machining process. The cutting machining device comprises a fixed base, a working frame, an equidistant propelling device, a storage box and a cutting device, the working frame is installed in the middle of the upper end of the fixed base, the equidistant propelling device is arranged in the working frame, the storage box is installed at the upper end of the working frame, a cutting device is arranged at the right side of the working frame and installed at the right side of the upper end of the fixed base. The device can solve the problems that according to a traditional rubber bar cutting machining treatment method, rubber bars are stacked on cutting equipment in a unified manner manually and then cut, due to the fact that manual stacking wastes time and labor, the efficiency of the method is low, the cutting machining progress is affected, when the rubber bars are cut and processed, uniform length processing of the rubber bars is generally lacked, and the cut and processed rubber bars are often different in length and are not easy to package, transport and use.
