Abstract:
1. Production machine for non-circular work pieces, comprising a tool and a tool carrier ( 2 ) that can move in an oscillating manner and a compensation body ( 3 ) that can move in an opposite direction relative to the tool that is used for impulse decoupling, movement of the tool is triggered or realized by a drive ( 4 ) acting between the tool carrier ( 2 ) and the compensation body ( 3 ), the drive ( 4 ) is a linear motor ( 11 ) or a plunger-type armature, the tool carrier ( 2 ) is supported by rolling bodies ( 5 ), the compensation body ( 3 ) is suspended by guide elements ( 6 ) on a housing part ( 7 ) of the production machine ( 1 ), and the compensation body ( 3 ) has a mass that is a multiple of a mass of the tool carrier ( 2 ) carrying the tool such that compensation strokes of the compensation body ( 3 ) corresponding to the oscillating movements of the tool carrier ( 2 ) lie in a range of an elastic deformation of the guide elements ( 6 ), a slide ( 14 ) that carries permanent magnets ( 15 ) of the linear motor ( 11 ) is mounted on the tool carrier ( 2 ), and the permanent magnets ( 15 ) are at least one of covered or connected with a material bond on both sides facing the stator ( 12 ) of the linear motor ( 11 ) with a cover ( 16 ), and an intermediate space ( 17 ) holding the permanent magnets ( 15 ) between the covers ( 16 ) is plugged with a sealing compound.
