20160107291 | CONTINUOUS-GENERATION GEAR-WHEEL GRINDING METHOD - A continuous-generation gear grinding method of conducting a gear grinding process such that while a thread-shaped grinding wheel is rotated around an axial center thereof and fed in an axial center direction, a position coming into contact with abrasive grains is constantly changed in the presence of a water-soluble grinding fluid by performing a grinding feed in a direction parallel to an axial center of a gear blank and by serially rotating the gear blank around the axial center, the grinding wheel being a vitrified grinding wheel having abrasive grains bonded by a vitrified bond with pores formed among the abrasive grains, and the abrasive grains having a grain size of F120 to F180. | 04-21-2016 |
20120101016 | METAL ROLLING OIL COMPOSITION - The present invention provides a metal rolling oil composition excellent in both an emulsion stability and a plating-out property, wherein the metal rolling oil composition comprises: at least one base oil selected from the group consisting of a mineral oil, animal and vegetable fat and oil, and synthetic ester; a surfactant; and an elastomer. | 04-26-2012 |
20100093868 | WATER-SOLUBLE METAL-PROCESSING AGENT, COOLANT, METHOD FOR PREPARATION OF THE COOLANT, METHOD FOR PREVENTION OF MICROBIAL DETERIORATION OF WATER-SOLUBLE METAL-PROCESSING AGENT, AND METAL PROCESSING - Disclosed are a water-soluble metal-processing agent and a coolant both of which have excellent microbial deterioration resistance and are less likely to go rotten, a method for preparing the agent or the coolant, and a metal processing method. The water-soluble metal-processing agent or the coolant comprises an N,N,N′,N′-tetraalkyldiamine compound. The metal processing method is characterized by processing a metal of interest by using the water-soluble metal-processing agent or the coolant. | 04-15-2010 |
