The invention relates to the technical field of wire cutting, in particular to an oil-gas lubrication control method and system, a medium, a control device and a wire cutting machine. The invention aims to solve the problems of low automation degree, difficulty in adhesion of a lubricant, high cost and low cleanliness of a bearing box lubricating mode. In order to achieve the purpose, the oil-gas lubrication control method is used for the oil-gas lubrication system and comprises the steps that when the oil-gas lubrication interval duration of a to-be-lubricated part reaches the preset interval duration, the oil-gas lubrication system is controlled to inject oil gas into the to-be-lubricated part; and when the oil-gas lubrication duration reaches the first preset duration, the oil-gas lubrication system is controlled to stop injecting oil gas into the to-be-lubricated component. Oil gas can be intermittently and automatically supplied to the to-be-lubricated component, the lubrication automation ...

The invention relates to the technical field of wire cutting, in particular to a grease lubrication control method and system, a medium, a control device and a wire cutting machine. The invention aims to solve the problems of high cost and low cleanliness of a current manual lubrication mode. In order to achieve the purpose, the grease lubrication control method comprises the steps that when it is detected that a first lubrication interval duration reaches a first preset interval duration, a first inlet of a switching valve is controlled to communicate with a first outlet, and a grease supply assembly is controlled to inject lubricating grease into a first to-be-lubricated component; and when it is detected that the first lubricating duration reaches the first preset duration, the grease supply assembly is controlled to stop injecting the lubricating grease into the first to-be-lubricated component. According to the method, the first to-be-lubricated component can be automatically oiled ...

The invention relates to the technical field of wire cutting, in particular to a control method of a wire cutting machine, a medium, a control device and the wire cutting machine. The wire cutting machine aims to solve the problem of wire jumping or wire breaking caused by diameter change of a wire roller in the cutting process of an existing wire cutting machine. The control method comprises the steps that whether a preset shaft diameter change condition is met or not is judged; if the preset shaft diameter change condition is met, the target rotating speed of the wire roller is calculated; and the current rotating speed of the wire roller is controlled to be the target rotating speed, so that the linear speed difference value of the linear speed of the cutting wire on the wire roller and the linear speed of the cutting wire on the main roller is within the set difference value. By means of the arrangement, the consistency of the linear speed of the cutting line on the line roller and ...
