An intelligent switching system for switching internal cooling and external cooling and a method are provided. The system includes a vision system, a cooling system and a control system. The vision system monitors a real-time milling state of a cutter, collects a real-time milling depth image that the cutter mills a workpiece, and transmits the collected real-time milling depth image to the control system. The control system includes a lubrication mode control center, and a motor control center. The lubrication mode control center receives the real-time image transmitted by the image collection control center; analyzes and processes the real-time image to obtain real-time milling depth data of the cutter. The motor control center receives a signal sent by the lubrication mode control center; analyzes and processes the signal, and transmits a control instruction to the cooling system. The cooling system executes a switching command issued by the control system.

A method of priming a minimum quantity lubrication (MQL) tool includes determining a category of the tool, supplying a short-prime MQL dosage if the tool is a first category or if both a second category and lubricated within a first predetermined timeframe, and supplying a long-prime MQL dosage if the tool is the second category and has not been lubricated within the predetermined timeframe. The category is based on internal passage complexity of the tool.

There is provided a bearing lubrication application control system which comprises a digital controller device operably coupled to a lubrication meter and a computer readable medium reader.

A system includes a machine tool that includes a cutting tool, a fluid subsystem that provides fluid to the cutting tool, and at least one processor that executes instructions that cause the at least one processor to: obtain a signal indicative of a load on the cutting tool, establish a first value of at least one parameter of the fluid based on the signal, obtain a second value of the at least one parameter that is based on a simulation, determine a difference between the first value and the second value, and adjust a state of a device of the fluid subsystem based on the determined difference.

A method of priming a minimum quantity lubrication (MQL) tool includes determining a category of the tool, supplying a short-prime MQL dosage if the tool is a first category or if both a second category and lubricated within a first predetermined timeframe, and supplying a long-prime MQL dosage if the tool is the second category and has not been lubricated within the predetermined timeframe. The category is based on internal passage complexity of the tool.

In a method for operating a machine tool, a machine-specific flow resistance and a respective tool-specific flow resistance are ascertained for various tools. Tool-specific regulator parameters for regulating a pump of a coolant lubricant device are computed on the basis of the machine-specific flow resistance and the tool-specific flow resistance of the tool chucked in a tool spindle. Subsequently, the machine tool is operated using the tool-specific regulator parameters. In this way, a rapid and exact feed of coolant lubricant to the machining point of the respective chucked tool is enabled in a simple and flexible manner.

A separative high-pressure cooling and lubrication method is provided. The method includes: S1: apply ultrasonic vibration on the cutting tool on a machine tool; S2: deliver high-pressure cutting fluid to a jet nozzle so as to spray the high-pressure cutting fluid to the cutting zone of the ongoing process. The method also includes: S3: set cutting parameters and ultrasonic vibration parameters to adjust the separation amount between the cutting tool and workpiece, and adjust the pressure of the high-pressure cutting fluid; S4: when the cutting tool and the workpiece separate completely with each other periodically, the high-pressure cutting fluid enters and flows through the interior of cutting zone, forming liquid film on the surfaces of the cutting tool and the workpiece. In step S4, the cutting tool and the workpiece and cooled, and liquid film is formed on the surfaces of the cutting tool and the workpiece.
