In recent years, due to the continuous improvement of workers' wages, many enterprises have difficulty in recruiting workers, which forces enterprises to update and transform equipment, improve the automation degree of equipment, and thus reduce the labor cost. The new generation of oil bath feeder has further improved its practicability, safety and reliability, carried out a series of technical improvements, and optimized the material selection, connecting structure, exhaust device, filtering device and push rod rotating device of the fuselage. Thus, various common problems of the oil bath feeder are solved, such as vibration, leakage, oil circuit blockage caused by the feeding of the machine body, and the contact end between the feeder and the processed material is easy to deform and jump due to the long-term rotation of the processed material. Therefore, the oil bath feeder can be widely used in various CNC lathes and has a good development prospect.
