Common laser cutting machine spindle lubrication

Common spindle lubrication method are two kinds of laser cutting machine, and oil and gas lubrication method similar to the oil mist lubrication method, but the oil mist lubrication is a continuous supply of oil mist, and oil and gas lubrication is regularly sends oil mist to bearing gap quantitatively, such already realized the oil mist lubrication, and avoids the oil mist too much and contaminated the surrounding air. Injection lubrication method is to use a larger flow of constant temperature oil ( Each bearing 3 ~ 4 l/min) Injection to the main shaft bearing, in order to achieve the purpose of lubrication, cooling. Larger flow injection oil must be here by the drainage pump oil discharge, rather than natural backflow. At the same time, also USES the large capacity and high precision of constant temperature tank, control the oil temperature change + 0. 5℃。
