What is the purpose of a grease gun in machine tools?

The purpose of a grease gun in machine tools is to insert grease into zerk fittings. Zerk fittings, also known as grease fittings, are small fittings used to supply grease to the bearings and other moving parts of machinery. This lubrication is essential for reducing friction, preventing wear, and prolonging the life of the components in the machine. Using a grease gun ensures that the right amount of grease is applied to specific areas without over-lubricating, which can lead to issues like grease leaking out or attracting dirt and grime.

In contrast, applying cutting fluid involves a different method and equipment; cutting fluid usually requires delivery systems integrated into the machine to help with cooling and lubrication during machining operations. Cleaning machines typically involves the use of rags, brushes, or other cleaning agents instead of a grease gun. Adjusting machine parts often requires tools like wrenches or alignment devices, not a grease gun, which is specifically designed for lubrication purposes. Thus, the function of a grease gun is distinctly focused on maintaining the lubrication and operational efficiency of equipment via zerk fittings.
