Marine Diesel Engines (2 - Stroke)
Two methods are used, a geared drive and a chain drive. Chain drives are relatively light, narrow in width and flexible; however they elongate in service due to wear, which will affect the camshaft timing, and they have a limited life - 15 years. Gear drives should last the life of the engine; However, a gear train is heavier, and more expensive.

How to Use a Surface Grinder Machine
A surface grinding machine is used to produce a smooth accurate finish on either metallic or nonmetallic materials. It uses a round rotating abrasive grinding wheel that remains stationary (but rotating) while the feed table (with work attached) is run in a reciprocating motion (left and right) under the grinding wheel.

The stress intensity and the number of stress events determine the specific energy to achieve a certain product fineness. The number of stress events is a function of mill operating parameters such as grind time, stirrer speed, percent solids and media size. The relationship between stress intensity and specific energy was shown by Kwade as indicated in Figure 10.10.
