Trunnion Bearings of Grinding Mill The trunnions are an integral part of the steel heads and are turned true with the axis of the mill. After machining, the trunnions are given a polished surface to minimize friction. The mill trunnions are carried on heavy babbitt bearings which provide ample surface to insure low bearing pressure.

In machining, several operations occur in a planned sequence to achieve the best results. We cover three of the most common operations including turning, drilling, and milling. Machining is a very common and versatile manufacturing process. Thus, it's possible to machine various types of material using these three methods.

Face mills are tools with a large diameter that are used to cut a wide shallow path for facing operations. Facing is used for machining a large flat area, typically the top of the part in preparation for other milling operations. A face mill is a solid body that holds multiple carbide inserts that can be replaced as they wear out.

The limitations of machining process are as follows. The accuracy of the components produce is dependent on the efficiency of the operator. Consistency in manufacturing is not present. Hence 100% inspection of the component is required. The personal needs of the operator are reducing the production rates.
