Lubricant

Differences between coolant and lubricant

During conventional machining or metal cutting, excess material is gradually removed from the workpiece in the form of chips using a wedge shaped cutting tool. Primarily due to continuous rubbing between moving chips and rake surface of cutting tool, intense heat is generated at the cutting zone. In continuous machining, this cutting heat leads to increase in temperature at the cutting zone. Excessive cutting temperature has several detrimental effects on

Differences between dry machining and wet machining

Machining is one secondary manufacturing process that is performed to impart desired shape, size and surface finish by removing unwanted material from a solid 3-D blank. In conventional machining operations, the cutting tool compresses a thin layer of workpiece material to gradually shear it off in the form of chips. The primary shear zone exists surrounding the concentrated shear plane along which work material undergoes shearing to become chip. Initially

Differences between flood cooling and MQL

In conventional machining operations, the cutting tool comes in physical contact with the workpiece to remove material in the form of chips. This chips flow over the rake surface of the tool before leaving the cutting zone. Presence of relative velocity under high contact pressure between the flowing chips and rake surface of the tool leads to excessive rubbing and heat generation. Excessive cutting heat or temperature has several detrimental
