A machining device (1) comprising a housing (2), a spindle (4) comprising at least one bearing, a pulse shaft (11), an amplitude disc (8) coupled to the pulse shaft (11) and arranged concentric to it, the pulse shaft (11) defining an axial direction (AD), the amplitude disc (8) further comprising at least one recess (20), in which a sled (24) is arranged. The sled (24) has an irregularity (28), which comprises a concave part as seen in a plane defined by the amplitude disc (8). The machining device (1) further comprising at least one first elastic element (12a), a first motion link (14a) and a first embedding disc (10a) comprising at least one contact element (26), the first embedding disc (10a) being arranged concentric to the amplitude disc (8) and the spindle (4) being coupled to the first embedding disc (10a), the first motion link (14a) being connected to the housing (2) and the first embedding disc (10a). The at least one first elastic element (12a) abutting the housing (2) with one end and the first embedding disc (10a) and/or the first motion link (14a) with the other end for pre-tensioning the first embedding disc (10a) towards the amplitude disc (8), whereby the contact element (26) of the first embedding disc (10a) is abutting the amplitude disc (8) and the irregularity (28) at least once per turn when the machining device is in use, so that a relative rotation between the amplitude disc (8) and the first embedding disc (10a) results in vibration in the spindle (4).
A machining device comprising a housing, a spindle comprising at least one bearing and adapted to hold a component, a pulse shaft, an amplitude disc coupled to the pulse shaft and arranged concentric to it, the pulse shaft defining an axial direction, the amplitude disc further comprising at least one recess, in which a sled is arranged, the sled having an irregularity, which comprises a concave part with regard to a plane defined by the amplitude disc, the machining device further comprising at least one first elastic element, a first motion link and a first embedding disc comprising at least one contact element, the first embedding disc being arranged concentric to the amplitude disc, the spindle being coupled to the first embedding disc, the first motion link being connected to the housing and the first embedding disc, the at least one first elastic element abutting the housing with one end and the first embedding disc and/or the first motion link with the other end for pre-tensioning the first embedding disc towards the amplitude disc, wherein the contact element of the first embedding disc is abutting the amplitude disc and the irregularity at least once per turn when the machining device is in use, so that a relative rotation between the amplitude disc and the first embedding disc results in vibration in the spindle.
