DRILLING HEAD WITH VIBRATION EFFECT Russian patent published in 2003 - IPC

FIELD: processes and equipment for mechanically working parts, drilling them by small depth. SUBSTANCE: head is designed for mounting in machine tool having axis for mechanically working by means of penetrating tool such as drill and it includes: body having members for joining it with machine tool; holder of cutting tool having members for mounting in it respective cutting tool; guide acting along working axis and designed for guiding holder of cutting tool relative to body of head. In order to simplify design of head the last includes elastically deformed member whose size parameters provide auto-sustaining of reciprocation movements or vibrations of cutting tool holder at process of controlled translatory feed of body relative to worked part. Guide has two plates elastically deformed in axial direction. Each plate includes inner and outer portions joined or fixed respectively to body and to cutting tool holder in order to construct means for suspending cutting tool holder on body of head. EFFECT: improved design of drilling head. 12 cl, 7 dwg
