LUBRICANT FOR METALLIC MATERIAL WORKING AND A METHOD OF PRESS WORKING A METALLIC MATERIAL |
摘要 |
[Object] To provide a lubricant for metallic material working and a method of press working a metallic material that makes it possible to improve the working accuracy of a press worked product and prolong the life of the die assembly beyond prior levels of life. [Solution] A lubricant for metallic material working comprises a mixture of a sulfur-based extreme pressure agent, an organic zinc compound, a calcium-based additive, and an ester compound, with lubricant base oil. The sulfur-based extreme pressure agent has a sulfur content of 5% by weight or higher based on the total weight of the lubricant. The organic zinc compound has a zinc content of 0.5% by weight or higher based on the total weight of the lubricant. The calcium-based additive has a calcium content of 0.5% by weight or higher based on the total weight of the lubricant. And the ester compound occupies a content of 1.0% by weight or higher based on the total weight of the lubricant. Additionally, the solution includes a method of press working a metallic material that employs such a lubricant. |
