A PROCESS AND AN APPARATUS FOR SUPPLYING THE INTERFACE BETWEEN AN ABRASIVE TOOL AND A WORKPIECE WITH COOLING LUBRICANT

摘要

The present invention relates to a process to supply the interface zone between an abrasive tool and a work piece with cooling lubricant. This process incorporates the following steps: a) provision of an annular gap (4) around the outside contour (5) of the abrasive tool (1), said annular gap (4) extending around the major portion of the periphery of the abrasive tool (1); b) interruption of the annular gap (4) in a first area (6) in which the interface zone (3) between the abrasive tool (1) and the work piece (2) is located; c) interruption of the annular gap (4) in a second area (7) that is located in an area of the periphery of the abrasive tool (1) that is spaced apart from the first area (6); d) delivery of cooling lubricant to the second area (7). This means that the cushion of air that forms around the rotating abrasive tool is broken down, so that even a small flow of oil will be sufficient to cool and lubricate the interface between the tool and the workpiece effectively.
