Claims (1)

Формула изобретенияClaim Способ двухцилиндричёской Заточки сверла при его возвратно-поступательном движении относительно двух (Q шлифовальных кругов, установленных на параллельных осях, отличающийся тем, что, с целью.формирования на каждом зубе сверла минимум двух цилиндрических поверхностей , _ и одной поверхности вращения, ему э во время заточки сообщают дополнительный поворот вокруг собственной оси, при этом шаг. поворота выбирают минимально возможным.The method of two-cylindrical Sharpening of a drill during its reciprocating motion with respect to two (Q grinding wheels mounted on parallel axes, characterized in that, for the purpose of forming at least two cylindrical surfaces on each tooth of the drill, _ and one surface of rotation, he e during sharpening reports an additional rotation around its own axis, while the step of rotation is chosen as low as possible.
