Abstract

<p>Outline of the cutting lubricants and the press working lubricants was described, and a lubrication mechanism of the cutting lubricants and the press working lubricants was explained on this paper. As for the cutting lubricants and the press working lubricants, the extreme pressure agent without chlorine was developed for an improvement of the working environment. In the press working lubricants, it was found that taking a sulfide type extreme pressure agent with a metal type detergent showed same level performance as chlorine type extreme pressure agents. However, it is thought that the regulation of chemical ingredient becomes more severe in the future. In recently, polymer type agent which consists of hydrogen, carbon, oxygen was developed. In this paper, press working properties of this polymer was expounded. Meanwhile, in development of the press working lubricants, the simulator which can evaluate processing properties of lubricants is necessary for a laboratory level. Therefore, the tester which was developed for adhesion simulation of drawing and ironing process was evaluated in this paper.</p>
