Abstract
The invention relates to a method and to a device for regrinding tools having straight or helical grooves with the help of a positioning head, which is provided with a feeler pin, which engages a groove and which, in the direction of advance, is disposed in front of the grinding disk. In order to make it possible to regrind the tool over the whole of its length, it is proposed pursuant to the invention that a positioning head with two feeler pins be used, the first feeler pin, which leads the grinding disk, being retracted from the groove before entry into the groove outlet or, if this groove runs out into the open, before leaving this groove and the second feeler pin, which is rigidly connected with the positioning head, trailing the grinding disk and, after removal of the first feeler pin from the groove, taking over the guidance of the spindle sleeve of the spindle head of the workpiece.
