Abstract

<p>Lubricants for plastic working of metals are materials is the chemical substances which penetrates to the interface between a tool and a workpiece, then controls friction and prevent seizure. These lubricants are classified into liquid, semisolid (grease) and solid according to their appearance. Liquid- and semisolid-type lubricants are mainly used in cold-working region, and solid-type ones are often applied to hot-working region. Liquid-type lubricants are the most commonly-used lubricant in the field of metal forming because it's easy to handle from their liquidity (hereinafter referred to as lubricating oils). Such the lubricating oils used in plastic working of metal materials are called by names of forming processes like rolling oil, drawing oil, forging oil, press oil, punching oil and so on. Among those, press oils and punching oils, which are used in processing sheet-metal into final parts, have high complication in application and wide variety in type. For example, based on material and dimension of processed parts, forming difficulty, and suitability on subsequent processes to final parts, the required functions as appropriate lubricants vary in detail. Focusing on press oils and punching oils, their required functions, activities for its advancing and the future outlook are outlined.</p>
