Electric control is the ideal way to control the development of goals, while addressing the basic control and fine control problems Raymond. Electric mill demand will gradually increase. In recent years, at home and abroad have been successfully developed a new type of electric adjustable rolling mill distance. Was equipped with a stepper motor and chain drive mechanism consisting of either using the original hand wheel adjustment Raymond 3r, can also be controlled by setting the requirements for remote computer operation. Stepping in intermittent or continuous rotation of the way quickly rolled away from the fine and quick adjustment Raymond 6r, it could go to the control panel, press the setpoint for closed loop automatic control. Raymond mill bearings are divided into two categories: the one is the Rolling Raymond, one is sliding bearings, roller bearings are divided into four parts: the balls and cage, inner, outer, and some also with the side bearing cover. Their principle is the same: the sliding friction in the form of limited position of the workpiece in the radial direction. Various properties of hydrostatic bearing is better than the dynamic pressure bearing, but the low cost dynamic pressure bearing.
