This application relates to the technical field of machine tool electric spindles, and discloses a milling machine tool electric spindle, a fault detection system, and a method. The milling machine tool electric spindle includes a stator, inside which a rotor is housed. Cooling chambers are provided at both ends of the stator, and flywheels are installed at both ends of the rotor, located inside the cooling chambers. The cooling chambers are connected by a connecting pipe, on which a circulation pump is installed. The rotor includes a central shaft and an armature winding mounted on the central shaft. A central coolant channel is provided within the central shaft, and coolant inlet and outlet channels are provided on the flywheels, communicating with the central coolant channel. A coolant branch channel is provided within the armature winding, communicating with the central coolant channel. A partition is provided in the middle of the central coolant channel. A speed sensor and a temperature sensor are installed inside the cooling chambers, and a vibration sensor is installed on the stator. This application has the effect of monitoring the working status of the electric spindle and preventing spindle damage.

The utility model relates to the technical field of drilling tool devices, in particular to an assembled deep hole steel plate drill which comprises a tool handle, a tool bar and a tool bit, the tool bar is connected with the tool handle and the tool bit in a threaded fit mode, the tool handle serves as a component connected with drilling machine equipment and is connected to the rear end of the tool bar, and the tool bit serves as an operation component and is connected to the front end of the tool bar. A spiral chip groove is formed in the outer wall of the tool bit. Due to the adoption of an assembled structure, when the steel plate drill fails, only the tool bit needs to be replaced, the whole steel plate drill does not need to be replaced, the cost can be effectively reduced after the steel plate drill is used for a long time, and an efficient and reliable solution is provided for various engineering operations related to extra-long and extra-large steel plate drilling. The specially-designed spiral chip removal grooves greatly enhance the chip removal capacity, it is guaranteed that the drilling process is smooth and free of hindrance, the drilling efficiency is greatly improved, and the machining quality is effectively improved. Due to the comprehensive application of the multi-blade tooth cutting structure and the wear-resistant coating, the steel plate drill can bear larger cutting force, the durability is remarkably improved, and the service life is prolonged.
