Abstract: The present disclosure relates to a grinding method for grinding of non-circular workpieces with an improved productivity and quality of the resulting workpiece. The method comprises a first and a second stage. The rotational speed profile of the workpiece in the first stage is controlled with the purpose of maintaining a pre-selected maximum surface temperature of the workpiece during said first stage, and grinding of the workpiece in said second stage is performed while controlling an aggressiveness number of said second stage so as to achieve an intended final surface quality. The present disclosure also relates to a method for determining the processing parameters of such a grinding method wherein the first and the second stage of the grinding method are iterated to thereby determine the processing parameters leading to a high productivity and desired quality of the workpiece after grinding.

Abstract: The disclosure relates to a lubrication and cooling device (1), comprising; a cooling fluid device (3), which comprises a first channel (5), which is connected to a first inlet port (7), and a lubricant fluid device (9), which comprises a second channel (11), which is connected to a second inlet port (13). The lubrication and cooling device (1) further comprises a heat exchanger (15), which comprises a cooling circuit (17) and a lubricant delivery circuit (19). The heat exchanger (15) is arranged to cool the lubricant fluid (24) by means of the cooling fluid (22), wherein the cooling fluid is a cryogenic fluid. The disclosure further relates to a method for lubricating and cooling a workpiece or a process by using a lubrication and cooling device (1), wherein the method comprises the steps of: a) cooling the lubricant fluid (24 by means of the cooling fluid (22) using the heat exchanger (15), and b) providing the cooled lubricant fluid (24) to the workpiece or process being lubricated and cooled.
