Abstract

FIELD: manufacture of screw taps. SUBSTANCE: sides of teeth of roll-threading lip are relieved separately by single-rib grinding wheel set for the angle of thread profile. Grinding wheel is moved along the teeth of roll-threading lip when relieving the left side of thread profile with value of axial feed less and the right side of thread profile with value of axial feed less and the right side of thread profile with value of axial feed more than thread pitch. Relationships for determination of indicated axial feed values depending on thread pitch, angle of thread profile and angle of teeth of roll-threading lip are offered. EFFECT: higher productivity and quality of relieving of upper parts of sides of teeth of roll-threading lip.

Изобретение позволяет повысить производительность и качество затылования (З) верхних частей боковых сторон зубьев заборного конуса (ЗК) метчика. З боковых сторон зубьев 3К производят раздельно однониточным шлифовальным кругом, заправленным на угол профиля резьбы. Круг перемещают вдоль ЗК при З левой стороны профиля резьбы с величиной осевой подачи (П) меньше, а правой стороны профия - с величиной П большей шага резьбы. Приведены зависимости для определения указанных П от шага резьбы, угла ее профиля и угла 3К метчика.The invention improves the productivity and quality of backing (Z) of the upper parts of the lateral sides of the teeth of the intake cone (ZK) of the tap. From the lateral sides of the teeth 3K, they are produced separately by a single-thread grinding wheel tucked at the angle of the thread profile. The circle is moved along the ЗК with З on the left side of the thread profile with the axial feed (П) value less, and on the right side of the profile - with П value greater than the thread pitch. Dependences are given for determining the indicated P from the thread pitch, the angle of its profile and the angle 3K of the tap.
