The utility model discloses an oil pressure system of a cut-off machine. The oil pressure system includes a switch control module, a decline control module, a rising control module, an oil return control module and an oil cylinder. There are an main oil circuit and a control oil circuit. The oil pressure system has a quick response, a high precision, a stable working and a low noise because most of the valves in the system adopts electromagnetic control, thus, the requirement of the mechanical automation control can be satisfied primely; the consumption of the energy and the circuit connection management are reduced because of the simple design of the oil circuit system; otherwise, the part lifetime is increased greatly and the internal drainage of the system is greatly reduced because of using a plug-in valve and a logical valve which has a big flow capacity, thus, the flow resistance of the hydraulic oil and the energy consumption are all reduced and the efficiency is improved.
