    摘要: Safe and structurally simple design for a finebore machine with a turning tool (3) mounted on a boring bar (2), whereby the excursion of the turning tool is produced by a piezoelectric servomotor without any magnetic actuation. This is achieved in the following manner: (a) the turning tool (3) is lodged in a spring-mounted tool holder (4) which is made to deflect by a translatory driving servomotor (6); (b) the driving direction of the servomotor (6) is perpendicular to the operating direction of the turning tool (3); (c) the driving strength of the servomotor (6) acts on the one end of a connecting rod (8) which is lodged separately from the servomotor (6); (d) the other end of the connecting rod (8) abuts on the free mobile end of the tool holder (4) in a fixed position relative to the latter. The shape of the bore to be produced can be preset as an electronic image.
