The mill is powered by a standard motor via a vertical gearbox . Segment thrust bearings in the gearbox absorb the roller forces. The grinding rollers are raised hydraulically from the grinding table prior to commencing grinding. This is realised by reversing the oil pressure exerted on the spring assembly cylinders.

• Most milling machines are equipped with power feed for one or more axes. Power feed is smoother than manual feed and, therefore, can produce a better surface finish. Power feed also reduces operator fatigue on long cuts. On some machines, the power feed is controlled by a forward reverse lever and a speed control knob.
