摘要： The present disclosure generally relates to a drilling tool having one or more locating brackets. The locating brackets include contacts that when engaged by a workpiece or a component adjacent to a workpiece, complete a pneumatic circuits of a pneumatic switch. Completion of the pneumatic circuits facilities operation of a drill of the drilling tool, thus allowing operation of the drilling tool and/or engagement of the drill with a workpiece. The locator brackets are sized and positioned such that engagement of the contacts occurs when the drilling tool is located in a predetermined position, thereby ensuring that drilling of a hole occurs in a desired location.

摘要： Disclosed is a clamping device of a balancing machine for coaxially clamping a toolholder on a spindle rotary about an axis of rotation (3), in which the coupling shank (8) is supported in the receiving socket only on discrete supports (11-15) which are spaced from each other circumferentially and lie in three relatively spaced engagement planes (E1, E2, E3) intersecting the axis of rotation (3). Four rigid discrete supports (11-14) are arranged in pairs in the first (E1) and the second (E2) engagement plane and combine to form a rigid support in a first radial direction. Formed in the third engagement plane (E3) lying between the first and the second engagement plane is a fifth discrete support (15) which effects a supporting function in a second radial direction opposite the first radial direction.

摘要： The invention relates to a centering bushing for centering a material bar which is supplied to a chuck of a lathe. An outer construction and an inner construction arranged therein are rotatably arranged about the longitudinal axis of a material bar. The inner construction is arranged to be rotatable with respect to the outer construction. The outer construction has means to fix the inner construction with respect to the chuck. The outer construction has a centrifugal force device which produces a force corresponding to the rotational speed. The inner construction has a centering device which leads to a centering of the material bar due to a force exerted on the centering device. A force transmission unit is arranged between the outer construction and the inner construction and ensures that the inner construction can rotate, with respect to the outer construction, and transfers the force produced by the centrifugal force device to the centering device.
